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-30-48P be used to power 48 V embedded computing modules or communication cards inside high-voltage power systems?

Yes. The PCB mounting format and 150–1500 VDC input make the DDRH-30-48P suitable for integration inside high-voltage converters or energy storage systems where a 48 V / 0.625 A (30 W) embedded auxiliary supply is needed for DSP boards, communication interfaces, or gate driver logic.

Is this unit appropriate for powering 48 V sensing or data acquisition modules in industrial automation equipment?

Yes. The DDRH-30-48P provides 48 V at 0.625 A (30 W) for sensors, data acquisition modules, or analog input cards that operate at 48 V. Its compact PCB footprint of 89.0 × 63.5 × 25.0 mm allows it to be mounted close to the load within the same enclosure.

Will the DDRH-30-48P operate in equipment that sees temperature extremes, such as outdoor metering units?

Yes, within its rating. The DDRH-30-48P is rated –40°C to +80°C (with load derating at higher ambient temperatures per the derating curve), so it can serve outdoor metering or monitoring units where temperatures swing widely, provided the enclosure protects it from moisture (20–90% RH non-condensing) and dust.

Can the DDRH-30-48P supply 48 V to VoIP gateways or networked automation controllers in a high-voltage DC panel?

It can provide up to 30 W at 48 V to a VoIP gateway or automation controller, provided the device's power draw does not exceed 0.625 A. The 150–1500 VDC input supports deriving this from a high-voltage DC distribution rail within that range.

How does the PCB-mount version compare to the DIN rail and screw terminal variants in the DDRH-30-48 family?

All three output 30 W at 48 V / 0.625 A from 150–1500 VDC with –40°C to +80°C range. The DDRH-30-48P (PCB) measures 89.0 × 63.5 × 25.0 mm and weighs 0.24 kg; the DDRH-30-48DR (DIN rail) is 135.0 × 70.0 × 43.5 mm at 0.31 kg; the DDRH-30-48ST (screw terminal) is 135.0 × 70.0 × 32.0 mm at 0.305 kg.

What certifications does the DDRH-30-48P carry?

The DDRH-30-48P is approved to UL1741, CSA C22.2 No.107.1-16, IEC62109-1 (LVD) and EAC TP TC 004.
