Key Takeaways
- The TPS100–320W Peak DR+ series is a compact DIN-rail power supply family from 100 W to 320 W, designed for industrial automation, LED, and telecom/IT infrastructure applications (depending on model and approvals).
- With efficiency of up to 93% (typ., depending on model and operating point), the series helps reduce cabinet heat. Convection cooling enables quiet, low-maintenance operation without fans.
- A wide input range of 85–264 VAC and 120–370 VDC, combined with adjustable outputs (12–15 VDC or 24–28 VDC, variant-dependent), supports flexible system design across multiple supply concepts.
- Integrated protection functions—such as overcurrent/overload protection (OCP/OLP), overvoltage protection (OVP), and overtemperature protection (OTP)—support robust operation in industrial environments (model-specific).
- Reliability data such as MTBF > 350,000 h is specified according to datasheet test conditions (e.g., at 25 °C). MTBF values are statistical estimates and must be interpreted in context.
The series is designed for engineers who need a dependable DIN-rail PSU platform that is easy to integrate and suited for demanding loads, including control cabinets, automation subsystems, and peak-load applications.

Overview of the TPS100-320W Peak DR+ Series
The TPS100–320W Peak DR+ series covers four power levels: 100 W, 150 W, 240 W, and 320 W. Each power level is available in variants with adjustable output ranges of 12–15 VDC or 24–28 VDC. Across the platform, the design focus is a compact footprint, high efficiency, robust protection features, and support for internationally used standards and approvals (as specified per model).
The input stage supports a wide operating range of 85–264 VAC and 120–370 VDC. This can simplify system design where equipment may be supplied from different mains voltages or DC bus levels, without changing the downstream 12 V or 24 V distribution concept—provided correct wiring and system-level design are applied.
High Efficiency and Thermal Performance
Efficiency is critical in enclosed control cabinets. Peak DR+ models achieve up to 93% efficiency at full load (depending on model and operating point), helping reduce heat dissipation and energy losses.
The series uses fanless convection cooling. With no moving parts, there is reduced wear and no fan-induced dust or acoustic noise, supporting long service intervals and clean cabinet environments.
The operating temperature range is specified as 0–70 °C, with linear derating above 50 °C (per datasheet). This allows reliable operation in warm cabinets, provided spacing, airflow, and derating recommendations are observed.

170% power boost for dynamic loads (10 seconds)
Automation, LED, and communication systems can create short-term peak demands, such as inrush currents or transient overloads. To address this, Peak DR+ models provide a 170% power boost for up to 10 seconds, according to datasheet conditions.
This additional headroom can support motor starts, actuator peaks, or capacitive loads while maintaining system stability when properly engineered. After a peak event, the power supply returns to normal operation based on its defined protection and recovery behavior.
Adjustable output for flexible system design
Depending on the variant, the series offers adjustable output ranges:
- 12–15 VDC variants for 12 V loads or lower-voltage electronics
- 24–28 VDC variants for standard industrial control, PLCs, relays, and field devices
Output adjustment allows compensation for cable voltage drops and fine-tuning of the DC bus voltage, within the specified adjustment range and system requirements.

Protection, Reliability and MTBF
Industrial environments demand predictable behavior under fault conditions. The TPS100–320W Peak DR+ series integrates protection mechanisms such as OCP/OLP, OVP, and OTP. Protection functions and thresholds are model-specific and defined in the datasheet.
Reliability metrics are specified as MTBF > 350,000 hours under defined test conditions (commonly at 25 °C and a specified load profile). MTBF is a statistical measure and not a guaranteed service life; it should be evaluated alongside thermal design, derating, and environmental factors.

Safety and EMC compliance (variant-dependent)
For international projects, safety and EMC compliance are essential. Peak DR+ models are designed to support compliance with common requirements; however, approvals and applicable standards are variant-dependent and must be verified in the datasheet and certificates for the exact model.
Appropriate compliant wording includes:
- “Approvals and compliance according to datasheet and model variant (e.g., CE and relevant safety and EMC standards).”
- “Designed for use in industrial control panels and related equipment, subject to the applicable standard set for the selected model.”
System-level CE marking must be performed for the final product. The power supply’s compliance documentation supports, but does not replace, the overall conformity assessment.
Typical Applications
Depending on variant and approvals, the TPS100–320W Peak DR+ series can be used in:
- Industrial automation: PLCs, distributed I/O, sensors, valves, motion controllers
- LED and building subsystems: 24 VDC distribution for lighting, signage, and building automation
- Telecom/IT infrastructure: network devices, routers, switches, gateways, and VoIP systems
- Machine building: decentralized control cabinets, safety subsystems, material handling, and machine tools
Model Selection Guide
Core models are available at 100 W (TPS100), 150 W (TPS150), 240 W (TPS240), and 320 W (TPS320), each with 12–15 VDC or 24–28 VDC variants. Typical front-panel elements include a status indicator (e.g., DC OK LED) and a front-access output adjustment (variant-dependent).
When selecting a model:
- Size for continuous load plus short-term peaks to utilize the 170% / 10 s power boost, where applicable
- Check ambient temperature, cabinet airflow, and derating above 50 °C
- Verify required approvals and standards for the target market and end equipment
- Confirm hold-up time, ripple/noise, inrush current, and EMC environment against system requirements
Conclusion
The TPS100-320W Peak DR+ series combines a wide input range, adjustable DC outputs, protection features, and high efficiency in a compact DIN-rail form factor. For new control panels or system upgrades, it provides a practical platform for industrial automation, LED distribution, and telecom/IT subsystems—particularly where short-term peak loads benefit from the specified 170% power boost for 10 seconds. Final selection should always be based on the datasheet for the exact model variant.
