Frequently Asked Questions
Can the DDRH-15-12DR power 12V sensors or transmitters from a high-voltage DC bus in a process control system?
Yes. The DDRH-15-12DR delivers 12V at 1.25A (15W) from a 150–1500VDC input, making it appropriate for supplying 12V loop-powered sensors, 4-20mA transmitters, or small instruments in process control panels connected to high-voltage DC buses.
Is the DDRH-15-12DR suitable for providing isolated 12V power to intrinsically safe barriers or Zener barriers?
The DDRH-15-12DR provides 15W at 12V/1.25A from a 150–1500VDC input and mounts on a DIN rail, which is a common configuration for IS barrier power feeds. Verify isolated output characteristics and relevant certifications for the specific IS application requirements.
Can I use the DDRH-15-12DR in a renewable energy cabinet where the input bus is 400–800VDC?
Yes. The 10:1 ultra-wide input range of 150–1500VDC makes the DDRH-15-12DR compatible with 400–800VDC input from solar or wind energy DC buses, supplying a regulated 12V/1.25A output for instrumentation or control circuits.
What is the operating temperature range of the DDRH-15-12DR?
The DDRH-15-12DR operates from -40°C to +80°C with a fanless design. This wide temperature range makes it suitable for outdoor equipment, cold-climate deployments, and high-ambient industrial enclosures.
How does the DDRH-15-12DR differ from the DDRH-15-12P and DDRH-15-12ST models?
All three deliver 15W at 12V/1.25A from 150–1500VDC input. The DDRH-15-12DR is DIN rail-mount (122.3 × 57.3 × 43.5 mm, 0.215 kg), while the DDRH-15-12P is PCB-mount and the DDRH-15-12ST uses screw terminals. Select the variant that matches your panel's mounting and wiring requirements.
