Frequently Asked Questions
Can I use the DDRH-30-15P to power sensors or control boards in high-voltage DC bus systems?
Yes. The DDRH-30-15P accepts 150–1500 VDC input, making it suitable for powering 15 V control electronics directly from high-voltage DC buses found in industrial automation, traction, and renewable energy systems. It delivers up to 2 A at 15 V, providing 30 W of isolated output for PLCs, sensors, or interface cards.
Is the DDRH-30-15P suitable for embedded systems that require PCB-mounted DC-DC conversion?
Yes. The DDRH-30-15P uses a PCB mounting type and measures 89.0 × 63.5 × 25.0 mm, making it appropriate for integration directly onto a PCB or within compact enclosures. Its fanless design eliminates moving parts, which is favorable for embedded or sealed assemblies.
Can this converter operate in cold-climate outdoor equipment or unheated enclosures?
The DDRH-30-15P is rated for –40°C to +80°C operating temperature, so it can function in unheated outdoor or industrial enclosures in cold climates. The fanless design also reduces the risk of mechanical failure in dusty or harsh environments.
Is the DDRH-30-15P appropriate for IT or telecom equipment drawing 15 V from a centralized high-voltage DC distribution rail?
It can be used in this context when the source bus voltage falls within the 150–1500 VDC input range and the load does not exceed 2 A (30 W). In IT rack or telecom applications with a centralized high-voltage DC rail, this converter provides a locally regulated 15 V supply for interface cards or ancillary circuits.
What mounting options are available in the DDRH-30-15 family for the same 30 W, 15 V output?
The 30 W 15 V variants are the DDRH-30-15P (PCB mounting, 89.0 × 63.5 × 25.0 mm, 0.24 kg), DDRH-30-15DR (DIN rail mounting), and DDRH-30-15ST (screw terminal, 135.0 × 70.0 × 32.0 mm, 0.305 kg). All three share the same 150–1500 VDC ultra-wide input range, 15 V / 2 A output, and –40°C to +80°C operating temperature.
Does the DDRH-30-15P carry CE certification?
Yes, the DDRH-30-15P holds CE and EAC certifications. It comes with a 3-year warranty.
