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-15-24DR power a 24V industrial sensor or proximity switch mounted in a DIN rail panel fed from a high-voltage DC bus?

Yes. The DDRH-15-24DR provides a regulated 24V/0.625A (15W) output from a 150–1500VDC input. DIN rail mounting allows it to be installed alongside PLCs and I/O modules, and it can power low-current 24V sensors, proximity switches, or encoder interfaces within the same panel.

Is the DDRH-15-24DR suitable for supplying 24V logic power to a field bus gateway or industrial Ethernet interface in a high-voltage DC cabinet?

The DDRH-15-24DR can supply 24V/0.625A to field bus gateways, industrial Ethernet interfaces, or HMI panel power inputs that require 24VDC at low current. Its DIN rail form factor integrates directly with standard control panel layouts, and the 150–1500VDC input range accommodates high-voltage DC distribution buses.

Can this DIN rail converter provide 24V auxiliary power in a battery management system or energy storage application?

Yes. With an input range extending to 1500VDC, the DDRH-15-24DR is compatible with the high-voltage bus voltages present in battery energy storage systems and EV battery management modules. It delivers 24V/0.625A for powering BMS control electronics, isolated communication interfaces, or safety relay coils.

What is the operating temperature range of the DDRH-15-24DR, and is it suitable for use in cold industrial environments?

The DDRH-15-24DR operates from -40°C to +80°C (with load derating at high ambient per the derating curve) and uses a fanless design, providing reliable cold-start operation in unheated industrial buildings or outdoor control cabinets. A protective enclosure is required for outdoor use since no IP rating is specified for the converter.

How does the DDRH-15-24DR compare to the DDRH-15-24P and DDRH-15-24ST variants?

All three 15W 24V variants deliver 24V/0.625A from a 150–1500VDC input. The DDRH-15-24DR (DIN rail, 122.3 × 57.3 × 43.5 mm, 0.215 kg) mounts on standard DIN rail; the DDRH-15-24P (PCB mount, 76.2 × 50.8 × 25.0 mm, 0.17 kg) is the smallest and mounts on a circuit board; the DDRH-15-24ST (screw terminal, 122.3 × 57.3 × 32.0 mm, 0.21 kg) connects via screw terminals for direct wiring. Selection depends on the mechanical integration required.

Is the 0.625A output current of the DDRH-15-24DR sufficient for common 24V control devices?

At 0.625A (15W), the DDRH-15-24DR can power 24V devices with modest current demands such as individual sensors, relays, signal isolators, or communication modules. Loads above 0.625A at 24V require a higher-power converter.
