Frequently Asked Questions
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. The operating temperature range of –40°C to +80°C covers extreme winter and summer conditions. The fanless design means no ventilation openings are required on the enclosure, supporting sealed or IP-rated cabinet installations.
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 wide temperature range and fanless construction are advantages in these environments.
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 carries CE and EAC certifications and is backed by a 3-year warranty.
