Frequently Asked Questions
Can the DDRH-15-24P power a 24V embedded system or single-board computer in a high-voltage DC power electronics design?
Yes. The DDRH-15-24P is a PCB-mount DC-DC converter with a 150–1500VDC input and 24V/0.62A (15W) output. Its compact 76.2 × 50.8 × 25.0 mm footprint enables direct board-level integration in power electronics designs where 24V logic power needs to be derived from a high-voltage DC bus.
Is the DDRH-15-24P appropriate for generating a 24V supply rail for isolated communication circuits in solar inverters?
Yes. The DDRH-15-24P accepts up to 1500VDC at its input, covering the string voltages present in utility-scale solar inverters. It can supply 24V/0.62A for isolated Modbus, CANopen, or other serial communication interfaces mounted on the control board of the inverter.
Can this PCB-mount converter supply 24V to a valve driver or actuator controller in a compact automation module?
The DDRH-15-24P provides 24V at up to 0.62A, which can power low-current 24V actuator controllers, solenoid driver ICs, or valve interface boards integrated onto a PCB. For higher current actuator loads, larger siblings in the series such as the DDRH-30-24P (1.25A) or DDRH-45-24P (1.87A) provide more headroom.
What thermal environment can the DDRH-15-24P tolerate in a sealed electronics enclosure?
The DDRH-15-24P operates from -40°C to +80°C without forced air cooling, owing to its fanless design. This makes it suitable for sealed enclosures where no ventilation is available, as long as the ambient temperature inside the enclosure stays within that range. The unit itself has no IP rating and relies on the external enclosure for environmental protection.
How does the DDRH-15-24P differ from the DIN rail and screw terminal 15W 24V options?
The DDRH-15-24P (PCB mount, 76.2 × 50.8 × 25.0 mm, 0.17 kg) is the most compact form factor in the 15W 24V group. The DDRH-15-24DR (DIN rail, 122.3 × 57.3 × 43.5 mm, 0.215 kg) and DDRH-15-24ST (screw terminal, 122.3 × 57.3 × 32.0 mm, 0.21 kg) are physically larger and suited to panel wiring applications. All three share 24V/0.62A output and 150–1500VDC input.
Does the DDRH-15-24P carry certifications needed for international industrial deployments?
Yes. The DDRH-15-24P holds CE and EAC certifications, covering European and Eurasian conformity requirements for industrial equipment. It is backed by a 3-year manufacturer warranty.
