Nätaggregat MEAN WELL DDR-30L-12

The MEAN WELL DDR-30L-12 is an ultra-slim DIN-rail DC-DC converter designed for industrial and automation applications. It accepts a wide input range of 18–75 Vdc and provides a single regulated 12 Vdc output capable of supplying up to 2.5 A (30 W). The compact housing (35 mm x 54.5 mm x 90 mm) and RoHS compliance make it suitable where space and environmental standards matter.

Advantages

The DDR-30L-12 offers a wide input voltage range for flexibility in different DC supply environments and a slim DIN-rail form factor for space-saving installation. Its regulated 12 V output ensures a stable power source for downstream devices while the compact dimensions allow integration into crowded control panels. Compliance with RoHS supports installations with material-restriction requirements.

Suitable for

• Industrial control cabinets and automation systems
• Rail-mounted power distribution in machinery
• Signal conditioning modules and small PLCs
• Applications requiring a compact 12 Vdc supply from varied DC sources

How to use

Mount the converter on a standard DIN rail inside the control panel, ensuring adequate ventilation and clearance from heat sources. Connect the DC input within the specified 18–75 Vdc range to the input terminals, observing correct polarity. Connect the 12 Vdc output to the load, verifying that the combined current draw does not exceed 2.5 A. Follow standard wiring practices and secure all terminal connections. Perform initial power-up checks to confirm stable output voltage before connecting sensitive equipment.

Recommendations

For reliable operation, avoid operating continuously at the maximum rated output in high ambient temperatures; allow some margin between expected load and the 2.5 A rating. Ensure proper fuse protection on the input side and observe EMC/grounding practices appropriate for industrial environments.
