Test conditions and notes4
- 1. All parameters NOT specially mentioned are measured at 800Vdc input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor.
- 3. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
- 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)

FAQ
Can the DDRH-30-12DR power small 12V PLCs or HMI panels mounted on a DIN rail?
Yes. The DDRH-30-12DR provides 30W at 12V and 2.5A in a DIN rail-mount package, making it suitable for powering compact 12V PLCs, HMI displays, or relay modules in a control cabinet. Its 10:1 ultra-wide input (150–1500VDC) allows operation from a wide variety of DC bus sources.
Is the DDRH-30-12DR suitable for 12V embedded control boards or single-board computers in industrial enclosures?
Yes. At 30W and 2.5A, the DDRH-30-12DR can power embedded control boards, single-board computers, or lightweight industrial computing platforms that operate at 12V. The DIN rail mount and -40°C to +80°C operating range (with derating per the derating curve) suit enclosed cabinet deployments where space is a constraint.
Can this unit supply 12V sensors, encoders, or proximity switches in an automation system?
Yes. The DDRH-30-12DR's 30W and 2.5A output is appropriate for a cluster of 12V sensors, encoders, or proximity switches in machine automation. Its 10:1 input ratio (150–1500VDC) handles diverse DC bus voltages found in automation backbones.
What temperature range does the DDRH-30-12DR support for use in cold or high-heat environments?
The DDRH-30-12DR is rated for -40°C to +80°C operation (with load derating at higher ambient temperatures per the derating curve), covering cold storage, outdoor installations in cold climates, and high-ambient industrial settings. No IP rating is listed, so it should be installed in a suitable protective enclosure for environments with moisture or dust.
How does the DDRH-30-12DR differ from the DDRH-30-12P and DDRH-30-12ST variants?
All three variants share identical electrical specs: 30W, 12V, 2.5A, and a 150–1500VDC input range. The DDRH-30-12DR is DIN rail-mount (135.0 × 70.0 × 43.5 mm, 0.31 kg), the DDRH-30-12P is PCB-mount (89.0 × 63.5 × 25.0 mm, 0.24 kg), and the DDRH-30-12ST uses screw terminal mounting (135.0 × 70.0 × 32.0 mm, 0.305 kg). Choose based on your mounting requirement.
