TPS150-DR1S24A 150W 24V DIN Rail Power Supply with 170% Power Boost for Industrial Control Systems

Where the TPS150-DR1S24A fits in a 24 VDC control system

The TPS150-DR1S24A is positioned for industrial automation, LED lighting, and telecommunications equipment that needs a compact, enclosed DIN rail AC/DC supply. Its nominal 150 W output and 6.3 A current rating align with PLC racks, industrial controllers, sensors, relays, HMIs, communications devices, and other 24 VDC loads. The adjustable 24–28 VDC range is useful when the designer needs to compensate for cable voltage drop or align the bus with an approved load window.

The buying decision should start with the continuous load, not the headline wattage. Add the steady-state current of all loads, apply realistic simultaneity, include future expansion, and confirm the worst operating temperature. Loads with solenoids, motors, capacitive input stages, or other start-up peaks also require a time-current review. The unit’s temporary boost can help, but it is not a substitute for checking peak amplitude, duration, repetition rate, wiring drop, and protective-device coordination.

For procurement, the exact ordering reference matters: TPS150-DR1S24A, article number 901004402. TPS can support the product itself as well as equivalent DIN rail power supply selection, engineering consultation, integration questions, and project-level supply for global B2B customers.

Key electrical and environmental specifications

These values are strong screening inputs, but they do not replace a project-specific review. Dimensions, terminal torque, spacing, inrush current, short-circuit behavior, exact protection curves, parallel/series operation, and current certificate files are not fully established by the supplied summary datasheet. Include them in the RFQ when they affect design release.

How to evaluate the 170% power boost

At rated output, 170% corresponds to a temporary theoretical power level of about 255 W. For a 24 V bus, that is roughly 10.6 A; however, this arithmetic is only a screening aid. The actual available voltage and current during a transient depend on the operating point and protection behavior. Ask TPS to confirm the intended load profile rather than designing solely from the percentage.

Four boost checks before approval

1. Amplitude: measure or obtain the maximum start current at the lowest expected bus voltage.
2. Duration: ensure the event stays inside the specified 10-second boost window.
3. Repetition: disclose the duty cycle; repeated starts can create a different thermal condition from a single event.
4. Downstream behavior: confirm cable drop, branch protection, load undervoltage thresholds, and controller reset tolerance.

If the load has a short, high peak, the boost may reduce the need to oversize the supply. If the overload is sustained, frequent, uncertain, or occurs above 50°C, selecting a higher continuous rating is usually the more robust engineering path. TPS can compare this 150 W model with the broader TPS100–320W Peak DR+ power-boost range.

DIN rail integration, wiring, and thermal design

The datasheet specifies vertical installation on 35 mm DIN rail, either TS 35/7.5 or TS 35/15. Preserve the orientation because convection cooling relies on the expected air path. Do not treat a nominal 0–70°C rating as permission to deliver full power across that entire range: output derating begins at 50°C. The relevant temperature is the local ambient around the supply inside the energized enclosure, not the room temperature outside it.

Thermal review

At the stated 93% efficiency and 150 W output, a first-pass loss estimate is approximately 11.3 W. This is an engineering estimate derived from the datasheet efficiency, not an additional guaranteed specification. Add losses from neighboring devices, consider solar gain and enclosure sealing, and verify the final design under worst-case line, load, and ambient conditions. Keep ventilation paths clear and request required clearance information from TPS.

Wiring and voltage setting

The terminal range is AWG 26–14 (0.15–2.5 mm²). Conductor selection must still account for current, length, temperature, grouping, voltage drop, protective-device coordination, and applicable installation rules. Use suitable ferrules where required, follow the confirmed tightening torque, and document the output-voltage setting during panel test. Raising the output toward 28 V may improve remote voltage, but only if every connected load is approved for that voltage.

Panel builders should also define the upstream disconnect and protective device, PE and grounding concept, separation from noisy conductors, and branch protection on the DC side. For broader system architecture, TPS can combine DIN rail selection with enclosure and power-integration expertise such as the Sentinel-Y 42U power cabinet approach.

Reliability, protection, safety, and EMC review

The datasheet lists convection cooling, overtemperature protection, overvoltage protection, overload protection, automatic recovery, a five-year warranty, and demonstrated MTBF above 350,000 hours at full load and 25°C ambient. MTBF is a statistical reliability indicator under stated conditions; it is not a service-life guarantee. Procurement should consider warranty terms, operating stress, replacement strategy, and supply continuity alongside the numerical MTBF.

The supplied document states CE compliance with the Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU, and lists UL 508, UL 60950-1, and EN 60950-1. Because standards, editions, transition rules, product categories, and certificate scopes change, the project team should request current declarations and applicable certificates for the exact article number and target market. This is particularly important where a component approval must support a panel or machine certification. Treat datasheet markings as screening information, not a substitute for the controlled compliance file.

The document also states electromagnetic susceptibility testing to IEC 801 parts 2–6, Level 3. For an RFQ, specify the actual equipment environment, required immunity/emissions standards, cable lengths, grounding, enclosure type, and any sector-specific requirements. TPS can then confirm available evidence or recommend an equivalent solution whose documentation better fits the project.

Selection logic: when this 150 W model is the right choice

Select TPS150-DR1S24A when

• the system uses a 24 VDC bus and continuous demand remains within 150 W and 6.3 A after derating;
• temporary start-up peaks can be validated against the 170%/10-second boost;
• wide-range AC input, or the documented high-voltage DC input range, suits the architecture;
• vertical DIN rail mounting and convection cooling fit the enclosure;
• the project can validate current compliance documents and detailed integration data before release.

Consider another rating or architecture when

Continuous load, ambient temperature, expansion margin, or repeated peaks exceed the available envelope. A lower-power control panel may be better served by the TPS030–130W Pro Series, while larger or more dynamic loads can be assessed against the 100–320 W Peak DR+ family. Bench validation and programmable test sequences may instead call for a programmable desktop DC supply. TPS can help define the correct product class instead of forcing an unsuitable component into the design.

Frequently asked questions

What is the rated output of the TPS150-DR1S24A?

The datasheet specifies 150 W, 6.3 A, and an adjustable 24–28 VDC output. Confirm the selected setpoint and total load against both current and power limits.

Can the 170% boost be used continuously?

No. It is specified for up to 10 seconds with automatic recovery. Sustained or frequently repeated overloads require a load-profile and thermal review and may justify a larger supply.

Does the supply deliver full power at 70°C?

The operating range is stated as 0–70°C, but derating applies from 50–70°C. Request the derating curve and calculate available output at the actual internal cabinet temperature.

Which compliance documents should procurement request?

Request current declarations and applicable certificate files for article 901004402 and the destination market. Confirm the standard edition, product category, conditions of acceptability, and whether additional equipment-level testing is required.

Can TPS support an equivalent or integrated solution?

Yes. TPS can support selection, equivalent DIN rail products, customization or integration consultation, and project-level supply. Provide the complete operating and commercial requirements in the RFQ.
