The TPS-BM75053KTIF-S is a 53 kW, three-phase bidirectional AC/DC power module designed for high-voltage battery formation, battery pack aging, and regenerative power testing. With a rated DC voltage of 750 V, high-frequency isolation, CAN/RS485 communication, and a scalable architecture, it is intended for integration into industrial battery test and energy-recycling systems.
For electrical engineers, system integrators, panel builders, and procurement teams, selecting a bidirectional power module requires more than comparing rated power and efficiency. The module must be compatible with the battery voltage range, facility power supply, control architecture, installation environment, and intended operating conditions.
This article examines the electrical specifications, integration requirements, application suitability, and technical considerations associated with the TPS-BM75053KTIF-S. It also outlines the information engineering and procurement teams should establish before requesting a quotation or finalizing a system design.
Why the TPS-BM75053KTIF-S Matters During Technical Evaluation
In high-power battery testing and formation systems, the power conversion stage must accommodate both energy delivery to the battery and energy recovery during discharge.
A bidirectional AC/DC module supports this operating principle by allowing power to flow in both directions between the AC and DC sides. Depending on the system architecture, recovered energy can be returned to the AC-side electrical system rather than dissipated entirely as heat.
The TPS-BM75053KTIF-S combines several characteristics relevant to these applications:
- 53 kW rated power for high-power battery formation and aging equipment.
- 750 VDC rated voltage for high-voltage DC system architectures.
- Three-phase 380/400/415 VAC input for industrial electrical installations.
- Bidirectional AC/DC conversion for charging and regenerative discharge operation.
- Peak conversion efficiency of up to 96% in AC-to-DC operation and 95% in DC-to-AC operation, under the specified conditions.
- High-frequency isolation between the AC and DC power conversion stages.
- CAN and RS485 communication interfaces for integration into supervisory and industrial control systems.
- Expandable architecture for applications requiring multiple power modules.
These characteristics influence equipment sizing, thermal management, grid-interface design, control integration, and the overall system configuration.
For example, conversion efficiency affects both electrical losses and the amount of heat that the cooling system must remove. Power factor and harmonic distortion influence the AC-side electrical design, while communication interfaces determine how the module can be monitored and controlled.
The module should therefore be evaluated as part of the complete power conversion system rather than as an isolated component.
Further product information is available on the TPS-BM75053KTIF-S product page. Related configurations can be explored through the TPS bidirectional power module portfolio.
Selection Criteria Before Requesting a Quotation
The first step is to establish the DC-side operating requirements.
Although the TPS-BM75053KTIF-S has a rated DC voltage of 750 V, the complete battery operating voltage range must be checked against the module’s permitted DC voltage range. Nominal voltage alone is insufficient to establish compatibility with a particular battery stack.
The next consideration is the AC supply.
The module is specified for three-phase 380/400/415 VAC operation with a 3Ph+PE connection. Full-load operation is specified over an AC voltage range of 342–460 VAC, with derating below this range.
For international installations, engineers should consider the actual supply voltage, frequency, voltage variation, and site-specific electrical conditions rather than relying solely on nominal utility ratings.
The operating duty cycle is equally important. Battery formation and aging processes may involve repeated charging and discharging, extended operation, and changing power demands. The selected module and its cooling arrangement must be evaluated against these conditions.
Finally, engineers should determine whether bidirectional operation is required. Regenerative energy recovery is particularly relevant to battery cycling applications, whereas charging-only systems may not require the additional functionality of a bidirectional power stage.
Key Specifications for Module Selection
The following specifications provide a starting point for evaluating the TPS-BM75053KTIF-S in industrial battery formation and energy-recycling systems.
| Parameter | Specification |
|---|---|
| Model | TPS-BM75053KTIF-S |
| Rated power | 53 kW |
| AC connection | Three-phase, 3Ph+PE |
| Rated AC voltage | 380/400/415 VAC |
| Full-load AC voltage range | 342–460 VAC |
| AC frequency | 50/60 Hz ±5 Hz |
| Rated DC voltage | 750 VDC |
| Rated DC current | 70.7 A |
| Peak efficiency, AC to DC | Up to 96% at 400 VAC |
| Peak efficiency, DC to AC | Up to 95% at 400 VAC |

| Isolation | High-frequency isolation |
| Communication | CAN, RS485 |
| Cooling | Intelligent forced-air cooling |
| Expansion | Up to 20 units, subject to configuration |
The specification also lists a concatenation value of 2. Its meaning and application should be clarified when defining the final multi-module configuration.
Rated Power and DC-Side Compatibility
The rated power of 53 kW and rated DC current of 70.7 A establish the module’s nominal operating point at 750 VDC.
For battery formation and aging equipment, however, the complete voltage and current operating envelope must be considered.
Engineers should verify whether the required charging and discharging profiles remain within the module’s permissible operating limits across the battery voltage range.
This is particularly relevant where battery voltage changes substantially with state of charge or where test procedures require different current and power levels.
Efficiency and Thermal Design
The specified peak efficiency reaches 96% during AC-to-DC conversion and 95% during DC-to-AC conversion at 400 VAC.
These values are relevant to energy consumption and cooling-system design, particularly in installations where multiple modules operate for extended periods.
Peak efficiency should not be interpreted as constant efficiency across the complete operating range. Actual losses depend on operating conditions, including power level and conversion direction.
For system-level energy calculations, engineers should request the applicable efficiency characteristics across the intended operating range.
Power Factor and Harmonic Distortion
The specification lists a power factor of 0.99 and THDi below 5% at 400 VAC and full load, under the stated supply conditions.
These parameters are important when evaluating the module’s interaction with the facility electrical network.
Power factor influences the relationship between active and apparent power, while current harmonic distortion affects power quality and may influence upstream electrical equipment and installation requirements.
The specified values provide a basis for engineering evaluation but do not, by themselves, demonstrate compliance with all grid connection requirements applicable to a particular installation.
Isolation, Communication, and Scalability
High-frequency isolation is a relevant architectural characteristic when evaluating the electrical separation between the AC and DC sides of the conversion system.
Its implementation should be considered alongside the overall insulation concept, protection requirements, and applicable safety standards.
The CAN and RS485 interfaces provide communication options for industrial control integration. Before selecting the module, engineers should confirm the available protocol documentation, supported commands, operating parameters, and fault-reporting functions.
The specification indicates expansion capability of up to 20 units. For multi-module systems, the permitted configuration, control arrangement, current sharing, and operating limitations should be clarified with TPS.
Related Power Supplies for Supporting Equipment
A high-power bidirectional module is only one part of a battery test or formation installation. Control circuits, communication equipment, sensors, and other auxiliary devices may require separate power supplies.
Depending on the auxiliary power requirements, relevant product ranges include:
- TPS010-100W GP Series — compact DIN rail power supplies for auxiliary circuits.
- TPS030-130W PRO Series — DIN rail power supplies for industrial control applications.
- TPS100-320W Peak DR+ Series — DIN rail power supplies with Power Boost functionality.
For development and bench-level validation tasks, programmable DC power supplies such as the EA-PS 3200-02 C and EA-PSI 9000 DT may also be relevant, depending on the test requirements.
These products serve different functions and should be selected independently of the main bidirectional power stage.
Integration and Installation Considerations
Electrical compatibility is only one part of integrating a high-power module into an industrial cabinet or rack.
Mechanical dimensions, cooling airflow, installation clearances, environmental conditions, and communication access must also be considered during system design.
Mechanical Dimensions and Mounting
The TPS-BM75053KTIF-S specification provides the following dimensions:
| Configuration | Dimensions (W × H × D) |
|---|---|
| Without handle | 435 × 86 × 600 mm |
| With handle | 489 × 86 × 647.5 mm |
| Weight | Below 23 kg |
These dimensions should be checked against the intended enclosure or mounting arrangement, including the space required for power cables, communication connections, and maintenance access.
The installation documentation identifies reserved mounting holes and specifies that mounting screws must not exceed the available hole depth.
Panel builders should review the installation drawings and mounting requirements before finalizing the mechanical design.
Cooling and Airflow
The module uses intelligent forced-air cooling, with airflow directed from the front fan side toward the rear terminal side.
This airflow arrangement affects enclosure layout, ventilation openings, cable routing, and the placement of adjacent components.
In multi-module installations, the combined heat output must be considered when sizing cabinet ventilation or cooling equipment.
Airflow should not be restricted by nearby equipment, cable bundles, or enclosure structures. Required installation clearances should be confirmed using the manufacturer’s documentation.
The specified conversion efficiency can provide an initial basis for estimating thermal losses, but detailed cabinet thermal calculations should reflect the expected operating profile rather than peak-efficiency figures alone.
Ambient Temperature and Power Derating
The specification defines the following temperature conditions:
- −10°C to 45°C: Full-load operation.
- Above 45°C to 60°C: Output power derating to 80% capacity.
These limits are relevant to equipment installed in electrical rooms, production environments, and partially conditioned industrial spaces.
The temperature inside an enclosure may exceed the surrounding room temperature, particularly where several high-power modules operate simultaneously.
Engineers should therefore evaluate the expected internal cabinet temperature under the intended duty cycle.
Altitude and Humidity
Full-load operation is specified below 2,000 m altitude.
Between 2,000 m and 3,000 m, output power is derated by 1% for every additional 100 m of altitude.
The permitted relative humidity is 5% to 95%, non-condensing.
These limits should be included in the installation assessment, especially for equipment intended for international deployment or operation in environments with variable temperature and humidity.
Communication and System Control
CAN and RS485 communication support provides options for connecting the module to a supervisory controller or industrial automation system.
The appropriate interface depends on the system architecture and the available communication protocol.
During integration, engineers should clarify:
- Supported communication protocols and interface settings.
- Available operating commands and monitoring parameters.
- Fault detection, reporting, and reset functions.
- Communication behavior during abnormal operating conditions.
- Requirements for coordinating multiple modules.
- Data acquisition and logging requirements during commissioning and operation.
These details are important for integrating the power module into automated battery formation and aging processes.
Safety, Standards, and Documentation
The specification references IEC 62477-1 and EN 55032 as intended design compliance standards. It also mentions readiness for UL, CE, and TÜV certification.
These statements should not be interpreted as confirmation that the exact module configuration has obtained certification or that the complete installation complies with the relevant regulations.
Before procurement, engineering teams should request the applicable declarations, certificates, test documentation, and installation instructions for the specific product configuration.
The safety documentation should also be reviewed for operating restrictions, including maximum permitted AC and DC voltages, insulation requirements, and environmental limitations.
The specification identifies unsuitable environmental conditions such as corrosive gases, abnormal vibration, and salt spray exposure.
These restrictions should be incorporated into the installation assessment and commissioning documentation.
For higher-power or multi-module configurations, the complete system protection concept, including isolation, grounding, protective devices, and fault handling, requires separate engineering evaluation.
Applications in Battery Formation and Energy-Recycling Systems
The TPS-BM75053KTIF-S specification identifies battery pack aging, series cell formation, and energy-recycling power aging as intended applications.
These processes can require repeated charging and discharging over extended operating periods, making bidirectional power conversion relevant to the overall equipment architecture.
Battery Formation Systems
Battery formation involves controlled electrical charging and discharging processes.
For systems using series-connected cells or higher-voltage battery arrangements, the power conversion equipment must be compatible with the required voltage, current, and operating profiles.
The TPS-BM75053KTIF-S provides a 750 VDC rated bidirectional power stage that may be suitable for integration into such systems, subject to confirmation of the full electrical operating range and process requirements.
System designers should also evaluate how the power module interacts with the formation controller, measurement equipment, and battery monitoring and protection systems.
Battery Pack Aging and Cycling
Battery aging and cycling equipment may operate through repeated charge and discharge sequences.
In these applications, bidirectional power conversion allows the system to deliver energy to the battery during charging and recover energy during discharge.
Compared with architectures that dissipate discharged energy through resistive loads, regenerative systems can reduce the amount of energy converted directly into heat, depending on the operating conditions and overall system configuration.
For continuous or repetitive testing, the electrical duty cycle, cooling requirements, and control interfaces are therefore central selection criteria.
Energy-Recycling Power Test Systems
Energy-recycling test equipment uses bidirectional conversion to manage power flow between the equipment under test and the electrical supply or another connected energy system.
The TPS-BM75053KTIF-S may be considered for such applications where its voltage, current, power, and interface characteristics match the test architecture.
For grid-connected regenerative installations, engineers must also assess site-specific power quality, protection, and grid connection requirements.
The module’s specified power factor and harmonic distortion are relevant to this assessment, although system-level compliance must be evaluated separately.
Multi-Module Test Platforms
The specified expansion capability of up to 20 units makes multi-module configurations a relevant consideration for larger test installations.
Such architectures may be used where a single module does not provide the required power capacity or where the equipment design calls for several coordinated power stages.
However, the final topology must be confirmed with the supplier, including permitted module combinations, supervisory control, current sharing, protection, and derating behavior.
For applications requiring different voltage or power characteristics, TPS also provides information on AC/DC bidirectional power modules for cell formation and its wider bidirectional power module portfolio.

Engineering Review
Electrical engineers should first establish the compatibility of the DC operating range, AC supply, and required charging and discharging profiles.
The protection concept and communication architecture should then be assessed against the requirements of the complete test system.
For projects requiring several modules, the engineering review should include the permitted topology and coordination method.
Mechanical and Installation Review
Panel builders should confirm that the module can be installed with the necessary mounting, ventilation, electrical connections, and maintenance access.
Particular attention should be given to the front-to-rear airflow path and the availability of space around rear-mounted terminals.
Thermal evaluation should reflect the expected cabinet operating temperature and any applicable derating.
Procurement and Documentation Review
Procurement teams should request the documentation needed for internal technical approval and supplier qualification.
Where certification or conformity documentation is required, the available evidence should be confirmed for the exact product version rather than inferred from general product-family descriptions.
Quotation comparisons should also use consistent assumptions regarding configuration, accessories, quantities, delivery conditions, and required technical support.
