Frequently Asked Questions
Can the DDRH-15-15P supply 15V power to an embedded DSP or FPGA board operating in a high-voltage DC power system?
Yes. The DDRH-15-15P is a PCB-mount DC-DC converter with a 150–1500VDC ultra-wide input and a regulated 15V/1A (15W) output. Its compact form factor (76.2 × 50.8 × 25.0 mm) allows it to be integrated directly onto a PCB within a power electronics or embedded control system that rides on a high-voltage DC bus.
Is the DDRH-15-15P appropriate for generating 15V bias rails in a grid-tied inverter or UPS system?
Yes. The DDRH-15-15P accepts inputs from 150V to 1500VDC and can generate a stable 15V/1A auxiliary rail for gate drive bias circuits, cooling fan controllers, or monitoring electronics inside grid-tied inverters and UPS systems. Its fanless operation is advantageous in sealed power converter housings.
Can this PCB-mount converter power a 15V industrial field bus interface card or I/O module?
The DDRH-15-15P can provide 15V supply power to low-current field bus interface cards or digital I/O modules requiring up to 1A at 15V. Its PCB mounting makes it convenient to co-locate with the interface circuitry inside the same enclosure or board assembly.
What is the operating temperature range of the DDRH-15-15P, and is it suitable for use in an unheated industrial enclosure?
The DDRH-15-15P operates from -40°C to +80°C, which covers unheated industrial enclosures in cold climates. The fanless design eliminates concerns about fan failure in low-temperature environments. The unit should be housed inside a rated protective enclosure rather than exposed directly to outdoor elements.
How does the PCB-mount DDRH-15-15P compare to the DIN rail and screw terminal variants at 15W 15V?
The DDRH-15-15P (PCB mount) is the most compact option at 76.2 × 50.8 × 25.0 mm and 0.17 kg. The DDRH-15-15DR (DIN rail) and DDRH-15-15ST (screw terminal) are both larger at 122.3 × 57.3 mm footprint and approximately 0.21–0.215 kg. All three deliver identical 15V/1A/15W output from a 150–1500VDC input. PCB mounting is preferred for board-level integration, while DIN rail and screw terminal versions suit panel-level wiring.
Can the DDRH-15-15P be used in automation equipment rated for use in harsh industrial environments?
The DDRH-15-15P holds CE and EAC certification and operates across a -40°C to +80°C range, supporting use in harsh industrial environments. Its fanless design reduces maintenance requirements in dusty or vibration-heavy automation applications. Integration within a sealed or filtered enclosure is recommended for protection against contaminants.
