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-15-05ST supply 5V to low-power control electronics from a 1000V solar DC bus?

Yes. The DDRH-15-05ST accepts 150–1500VDC and provides 5V at 2A (10W), making it suitable for supplying control electronics, sensors, or small communication devices from a 1000V solar DC string or similar high-voltage bus.

Is the DDRH-15-05ST a good fit for panel builders who need screw terminal connections in a compact form?

Yes. The DDRH-15-05ST uses a screw terminal interface and measures 122.3 × 57.3 × 32.0 mm at 0.21 kg. It provides 5V/2A from 150–1500VDC input, suitable for panel builders who require direct screw termination rather than DIN rail clips or PCB mounting.

Can the DDRH-15-05ST power a 5V Modbus RTU module or serial communication adapter in an industrial panel?

The DDRH-15-05ST provides up to 2A at 5V, which is sufficient for Modbus RTU modules, RS-232/RS-485 serial adapters, and similar low-power industrial communication devices commonly requiring 5V supply rails.

Does the DDRH-15-05ST require a fan, and can it operate in dusty or sealed enclosures?

The DDRH-15-05ST uses a fanless design, making it well suited for sealed enclosures or dusty industrial environments where fan blockage or contamination would be a concern. It operates across -40°C to +80°C, with load derating at high ambient temperatures per the derating curve.

How does the DDRH-15-05ST differ from the DIN rail and PCB versions of the same model?

All three DDRH-15 5V variants output 5V at 2A (10W) from 150–1500VDC input. The DDRH-15-05ST is screw terminal-mount (122.3 × 57.3 × 32.0 mm, 0.21 kg), the DDRH-15-05DR is DIN rail-mount (122.3 × 57.3 × 43.5 mm, 0.215 kg), and the DDRH-15-05P is PCB-mount (76.2 × 50.8 × 25.0 mm, 0.17 kg). Choose based on preferred termination and mounting method.
