Frequently Asked Questions
Can the DDRH-30-12P be used to power a 12V embedded PCB or microcontroller-based industrial board?
Yes. The DDRH-30-12P is a PCB-mount DC-DC converter providing 30W at 12V and 2.5A, designed for direct board-level integration. Its compact profile (89.0 × 63.5 × 25.0 mm) makes it suited for embedding within industrial control boards, gateway devices, or custom automation hardware operating from a high-voltage DC bus.
Is the DDRH-30-12P appropriate for powering 12V communication modules on an automation PCB?
Yes. At 30W and 2.5A, the DDRH-30-12P can supply 12V RS-232, RS-485, CAN, or Ethernet communication modules integrated on a PCB. The 10:1 input range (150–1500VDC) allows the board to draw from a wide-range DC bus without an additional front-end converter stage.
Can this converter be used in industrial measurement or data acquisition systems?
Yes. The DDRH-30-12P's 30W output and PCB-mount form factor suit data acquisition systems, signal conditioning boards, and industrial measurement platforms that require a regulated 12V supply derived from a high-voltage DC bus. Its fanless design eliminates noise and vibration concerns in sensitive measurement environments.
What are the environmental operating limits for the DDRH-30-12P?
The DDRH-30-12P operates from -40°C to +80°C, making it suitable for cold-climate installations and high-ambient industrial environments. As a PCB-mount component, it relies on the host board or enclosure for environmental protection against moisture, dust, and vibration.
How does the DDRH-30-12P compare to the DIN rail and screw terminal variants for the same power level?
The DDRH-30-12P (PCB mount, 89.0 × 63.5 × 25.0 mm, 0.24 kg), DDRH-30-12DR (DIN rail, 135.0 × 70.0 × 43.5 mm, 0.31 kg), and DDRH-30-12ST (screw terminal, 135.0 × 70.0 × 32.0 mm, 0.305 kg) all provide 30W, 12V, and 2.5A with a 150–1500VDC input. The PCB variant is the most compact and lightest, suited for board-level integration rather than panel mounting.
