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 the DDRH-15-24P power a 24V embedded system or single-board computer in a high-voltage DC power electronics design?

Yes. The DDRH-15-24P is a PCB-mount DC-DC converter with a 150–1500VDC input and 24V/0.625A (15W) output. Its compact 76.2 × 50.8 × 25.0 mm footprint enables direct board-level integration in power electronics designs where 24V logic power needs to be derived from a high-voltage DC bus.

Is the DDRH-15-24P appropriate for generating a 24V supply rail for isolated communication circuits in solar inverters?

Yes. The DDRH-15-24P accepts up to 1500VDC at its input, covering the string voltages present in utility-scale solar inverters, and is approved to IEC62109-1. It can supply 24V/0.625A for isolated Modbus, CANopen, or other serial communication interfaces mounted on the control board of the inverter.

Can this PCB-mount converter supply 24V to a valve driver or actuator controller in a compact automation module?

The DDRH-15-24P provides 24V at up to 0.625A, which can power low-current 24V actuator controllers, solenoid driver ICs, or valve interface boards integrated onto a PCB. Loads drawing more than 0.625A at 24V need a higher-power converter.

What thermal environment can the DDRH-15-24P tolerate in a sealed electronics enclosure?

The DDRH-15-24P operates from -40°C to +80°C without forced air cooling, owing to its fanless design; at higher ambient temperatures the output load must be derated per the derating curve. This makes it suitable for sealed enclosures where no ventilation is available, as long as the ambient temperature inside the enclosure stays within that range. No IP rating is specified, so it relies on the external enclosure for environmental protection.

How does the DDRH-15-24P differ from the DIN rail and screw terminal 15W 24V options?

The DDRH-15-24P (PCB mount, 76.2 × 50.8 × 25.0 mm, 0.17 kg) is the most compact form factor in the 15W 24V group. The DDRH-15-24DR (DIN rail, 122.3 × 57.3 × 43.5 mm, 0.215 kg) and DDRH-15-24ST (screw terminal, 122.3 × 57.3 × 32.0 mm, 0.21 kg) are physically larger and suited to panel wiring applications. All three share 24V/0.625A output and 150–1500VDC input.

Does the DDRH-15-24P carry certifications needed for international industrial deployments?

The DDRH-15-24P is approved to UL1741, CSA C22.2 No.107.1-16, 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 for EMC.
