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-30-24DR power 24 V PLCs or I/O modules from a high-voltage DC bus in an industrial panel?

Yes. The DDRH-30-24DR mounts on a DIN rail and accepts 150–1500 VDC input, allowing it to step down a high-voltage DC bus to 24 V for PLCs, I/O modules, or relay coils. It delivers up to 1.25 A at 24 V (30 W total), which covers many single-channel 24 V control loads.

Is this converter a good fit for solar or energy storage systems that use a high-voltage DC intermediate bus?

The DDRH-30-24DR's 150–1500 VDC 10:1 ultra-wide input is well suited to the variable high-voltage DC buses found in solar string inverters and battery energy storage systems where bus voltage fluctuates widely. It provides a stable 24 V / 1.25 A auxiliary supply for control electronics, communication boards, or monitoring equipment.

Can the DDRH-30-24DR be installed in outdoor switchgear enclosures or in environments with wide temperature swings?

Yes, inside a suitable enclosure. The operating temperature range of –40°C to +80°C (with load derating at higher ambient temperatures per the derating curve) covers wide winter and summer swings. No IP rating is given and humidity must stay within 20–90% RH non-condensing, so the switchgear enclosure must provide environmental protection.

Is the DDRH-30-24DR suitable for powering 24 V instrumentation in oil-and-gas or heavy industrial plants?

It can supply 24 V / 1.25 A (30 W) to field instruments, signal conditioners, or loop-powered devices in plants where a high-voltage DC distribution rail is present and falls within 150–1500 VDC. The –40°C to +80°C operating range and vibration rating per MIL-STD-810F are advantages in these environments; the sheet lists no hazardous-location approvals.

How does the DIN rail version compare to the PCB and screw terminal variants of the DDRH-30-24?

All three deliver 30 W at 24 V / 1.25 A with 150–1500 VDC input and –40°C to +80°C range. The DDRH-30-24DR (DIN rail) measures 135.0 × 70.0 × 43.5 mm and weighs 0.31 kg; the DDRH-30-24P (PCB mount) is 89.0 × 63.5 × 25.0 mm and 0.24 kg; the DDRH-30-24ST (screw terminal) is 135.0 × 70.0 × 32.0 mm and 0.305 kg.

What certifications does the DDRH-30-24DR carry and what is the warranty period?

The DDRH-30-24DR is approved to UL1741, CSA C22.2 No.107.1-16, IEC62109-1 (LVD) and EAC TP TC 004. The spec sheet does not state a warranty period.
