Frequently Asked Questions
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 / 0.62 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 0.62 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. The DDRH-30-48P is rated –40°C to +80°C and uses a fanless design, making it appropriate for sealed outdoor metering or monitoring enclosures where no ventilation is available and temperatures can swing widely.
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 0.62 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 / 0.62 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 holds CE and EAC certifications and comes with a 3-year warranty.
