Frequently Asked Questions
Can the DDRH-30-24P supply 24 V power to embedded control boards inside high-voltage power conversion equipment?
Yes. The PCB mounting form factor and 150–1500 VDC ultra-wide input make the DDRH-30-24P well suited for integration inside high-voltage converters or inverters where a compact, board-mounted 24 V auxiliary supply is needed. It provides up to 1.25 A at 24 V (30 W) for gate driver boards, DSP controllers, or communication interfaces.
Is this converter appropriate for use in compact automation or robotics controllers that require a 24 V PCB-mounted supply?
The DDRH-30-24P's 89.0 × 63.5 × 25.0 mm footprint and PCB mounting type allow it to be integrated directly into automation or robotics controller assemblies. At 30 W it can power microcontrollers, CAN or EtherCAT interface chips, and sensor circuitry from a high-voltage input.
Can the DDRH-30-24P operate in unheated enclosures or equipment exposed to outdoor ambient temperatures?
Yes, with an operating range of –40°C to +80°C, the DDRH-30-24P handles cold-start conditions as low as –40°C. The fanless design prevents dust ingress issues associated with cooling fans, making it suitable for sealed enclosures in outdoor or semi-outdoor environments.
Is the DDRH-30-24P suitable for IT or telecom equipment that uses a 48 V or higher DC power shelf and needs a 24 V sub-rail?
If the DC shelf voltage falls within the 150–1500 VDC input range of the DDRH-30-24P, it can create a 24 V / 1.25 A sub-rail for auxiliary boards. For lower source voltages such as 48 V bus systems, this unit is not applicable since its minimum input is 150 VDC.
How does the PCB-mount variant compare with the DIN rail and screw terminal versions of the DDRH-30-24?
All three output 24 V / 1.25 A (30 W) from a 150–1500 VDC input with the same –40°C to +80°C range. The DDRH-30-24P (PCB) measures 89.0 × 63.5 × 25.0 mm and weighs 0.24 kg; the DDRH-30-24DR (DIN rail) is 135.0 × 70.0 × 43.5 mm at 0.31 kg; the DDRH-30-24ST (screw terminal) is 135.0 × 70.0 × 32.0 mm at 0.305 kg.
What certifications does the DDRH-30-24P hold?
The DDRH-30-24P is CE and EAC certified, and comes with a 3-year warranty.
