Frequently Asked Questions
Can the DDRH-15-05DR power a 5V embedded controller or Raspberry Pi from a high-voltage DC bus?
The DDRH-15-05DR provides 5V at up to 2A (15W) and accepts 150–1500VDC input, making it suitable for supplying 5V embedded controllers, single-board computers, or logic boards in systems connected to medium- or high-voltage DC buses.
Is the DDRH-15-05DR suitable for use in DIN rail automation panels that require a 5V auxiliary supply?
Yes. The DDRH-15-05DR is a DIN rail-mount unit that provides a 5V/2A output for low-power auxiliary loads such as sensors, indicators, or communication modules within automation panels. Its 122.3 × 57.3 × 43.5 mm footprint fits standard DIN rail enclosures.
Can I use the DDRH-15-05DR in a traction or railway application powered by a 750V DC bus?
Yes. The DDRH-15-05DR accepts 150–1500VDC input with a 10:1 ultra-wide range, covering 750V DC traction bus voltages. It supplies 5V/2A for onboard electronics or communication equipment powered from traction bus rails.
Does the DDRH-15-05DR operate in cold outdoor environments or extreme temperatures?
Yes. The DDRH-15-05DR is rated for -40°C to +80°C and uses a fanless design, making it appropriate for outdoor enclosures, cold-climate installations, and environments where fan maintenance is impractical.
What is the difference between the DDRH-15-05DR, DDRH-15-05P, and DDRH-15-05ST?
All three models provide 15W at 5V/2A with the same 150–1500VDC input range. The DDRH-15-05DR is DIN rail-mount (122.3 × 57.3 × 43.5 mm, 0.215 kg), the DDRH-15-05P is PCB-mount (76.2 × 50.8 × 25.0 mm, 0.17 kg), and the DDRH-15-05ST is screw terminal-mount (122.3 × 57.3 × 32.0 mm, 0.21 kg). Choose based on the required mounting method.
