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-45-24P power a 24V embedded controller inside a motor drive assembly?

Yes. The PCB-mount format makes the DDRH-45-24P easy to integrate directly into a drive assembly or custom controller board. It supplies 24V at 1.87A (45W) from a 150–1500VDC input, covering the high bus voltages typical of variable-frequency drives.

Is the DDRH-45-24P suitable for supplying 24V to an industrial wireless gateway in a smart factory application?

Yes. Industrial wireless gateways and IIoT edge devices commonly run on 24VDC and draw well under 45W. The PCB-mount module can be integrated into a custom gateway board or mounted inside an enclosure fed from any bus voltage in the 150–1500VDC range.

Can this module be used in a mining or heavy-industry application with high DC bus voltages above 800VDC?

The DDRH-45-24P accepts up to 1500VDC, making it compatible with the elevated bus voltages found in mining conveyor drives, longwall equipment, and heavy-industry automation. At 45W it serves auxiliary control and instrumentation loads.

How does the DDRH-45-24P PCB module compare to the other 45W 24V variants in the DDRH series?

All three 45W 24V models output 24V at 1.87A with a 150–1500VDC input. The DDRH-45-24P is the smallest at 89×63.5×25 mm (0.24 kg) and mounts on a PCB. The DDRH-45-24DR (135×70×43.5 mm, 0.31 kg) clips to a DIN rail. The DDRH-45-24ST (135×70×32 mm, 0.305 kg) uses screw terminals.

Does the DDRH-45-24P need any thermal management when embedded in a sealed device?

The sheet does not specify a cooling method, and output must be derated at higher ambient temperatures per the derating curve. In a sealed housing, ensure the enclosure provides sufficient thermal mass or surface area to keep the ambient around the converter within its –40°C to +80°C range.

Can the DDRH-45-24P handle the cold temperatures experienced in arctic or high-altitude outdoor equipment?

The –40°C lower temperature limit covers arctic and high-altitude cold-start conditions. Because the unit has no IP rating, it must be housed in an appropriately sealed enclosure to protect against condensation and precipitation in outdoor installations.
