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.

FAQ

Can I use the DDRH-15-12P to power a 12V embedded controller board in a high-voltage DC bus system?

Yes. The DDRH-15-12P accepts a 150–1500VDC ultra-wide input range, making it suitable for powering 12V embedded controllers or microcontroller boards directly off high-voltage DC distribution buses found in industrial and renewable energy systems. It delivers up to 1.25A at 12V for a maximum of 15W.

Is the DDRH-15-12P suitable for powering a 12V PLC or industrial sensor in a DIN rail cabinet that uses a high-voltage DC bus?

The DDRH-15-12P can power low-wattage 12V industrial devices such as sensors, signal isolators, or small PLCs. Its 10:1 ultra-wide input range (150–1500VDC) makes it appropriate for cabinets supplied from high-voltage DC buses, and its PCB mounting form factor fits compactly onto circuit boards within the enclosure.

Can this converter supply 12V bias power to a gate driver or auxiliary circuit in a power electronics system?

Yes. The DDRH-15-12P can supply 12V auxiliary or bias power in power electronics, motor drives, and inverter systems where a high-voltage DC bus (up to 1500VDC) is present. At 15W and 1.25A output, it is well-suited for logic-level bias circuits rather than high-current loads.

What temperature range does the DDRH-15-12P support for outdoor or harsh-environment deployments?

The DDRH-15-12P is rated for an operating temperature range of -40°C to +80°C, with load derating at high ambient temperatures per the derating curve. Its fanless design allows it to operate passively without airflow, making it suitable for sealed enclosures or locations with wide ambient temperature variation. No IP rating is specified, so it should be mounted inside a suitable protective enclosure for outdoor use.

How does the PCB-mount DDRH-15-12P differ from the DIN rail and screw terminal variants in the same 15W 12V family?

All three 15W 12V variants — DDRH-15-12P (PCB mount, 76.2 × 50.8 × 25.0 mm, 0.17 kg), DDRH-15-12DR (DIN rail, 122.3 × 57.3 × 43.5 mm, 0.215 kg), and DDRH-15-12ST (screw terminal, 122.3 × 57.3 × 32.0 mm, 0.21 kg) — share the same 15W output, 12V/1.25A rating, and 150–1500VDC input range. The difference is the mechanical mounting style: PCB mounting for board-level integration, DIN rail for panel mounting, and screw terminals for direct wire termination in enclosures.

Does the DDRH-15-12P carry CE certification, and is it suitable for use in European industrial equipment?

The DDRH-15-12P 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 equipment must be re-confirmed to meet EMC directives.
