Test conditions and notes4

1. All parameters NOT specially mentioned are measured at 800Vdc input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor.
3. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)

FAQ

Can the DDRH-15-15DR power a 15V analog signal conditioner or isolated amplifier in a DIN rail panel with a high-voltage DC bus?

Yes. The DDRH-15-15DR is a DIN rail-mounted DC-DC converter accepting 150–1500VDC input and delivering a regulated 15V/1A output (15W). It is appropriate for 15V analog instrumentation, signal conditioners, or isolated measurement modules mounted alongside other DIN rail components in industrial control cabinets.

Is the DDRH-15-15DR suitable for providing 15V excitation to strain gauge bridges or transducers in process control systems?

The DDRH-15-15DR provides a constant voltage 15V output at up to 1A, which can supply excitation to low-current transducers, strain gauges, or pressure sensors in process automation. Its wide input range (150–1500VDC) allows it to operate from high-voltage DC process bus supplies.

Can this DIN rail converter power a 15V DC relay coil array or solenoid valve driver in an automation panel?

The DDRH-15-15DR can drive 15V relay coils or solenoid valve circuitry within its 15W/1A capacity. Care should be taken to ensure the total inrush and steady-state current of the connected coils remains within 1A, and that output capacitance does not exceed 1000μF.

How does the DDRH-15-15DR perform in cold-start or outdoor-adjacent applications with extreme ambient temperatures?

The DDRH-15-15DR is specified for operation from -40°C to +80°C (with load derating at high ambient per the derating curve), enabling cold-start capability in sub-zero environments such as outdoor control cabinets or northern industrial facilities. Its fanless construction ensures no fan wear at temperature extremes. For outdoor installation, a rated enclosure is required since no IP rating is specified for the unit.

What is the difference between the DDRH-15-15DR, DDRH-15-15P, and DDRH-15-15ST?

All three share the same electrical specs: 15W output, 15V/1A, and 150–1500VDC input. The DDRH-15-15DR (DIN rail, 122.3 × 57.3 × 43.5 mm, 0.215 kg) mounts on a standard DIN rail; the DDRH-15-15P (PCB mount, 76.2 × 50.8 × 25.0 mm, 0.17 kg) mounts onto a PCB; and the DDRH-15-15ST (screw terminal, 122.3 × 57.3 × 32.0 mm, 0.21 kg) provides screw terminal wiring. The choice depends on mechanical integration requirements.

Does the DDRH-15-15DR carry relevant certifications for use in European industrial machinery?

The DDRH-15-15DR is approved to IEC62109-1 (LVD) and EAC TP TC 004, and meets BS EN/EN55032 Class A emissions (with external components) and BS EN/EN55035 immunity. As a component, the final machine must be re-confirmed to meet EMC directives.
