Power Adapter MEAN WELL DDR-120C-12 120W 12V Input 33.6-67.2V

The MEAN WELL DDR-120C-12 is an ultra-slim industrial DC-DC DIN-rail converter delivering a single 12Vdc output at 10A (120W) from a wide input range of 33.6–67.2Vdc. Designed for cabinet and control-panel installations, the unit is RoHS compliant and features compact dimensions (32 mm W × 102 mm D × 125.2 mm H) to save space in industrial environments.

Advantages

The DDR-120C-12 provides stable 12V output with 120W power in an ultra-compact housing suitable for DIN-rail mounting. Its wide input voltage range allows use with different battery or intermediate-voltage systems. Compliance with RoHS supports installations that require restricted-hazardous-substance components. The slim profile and standardized rail mounting simplify integration into control cabinets and automation racks.

Suitable for

• Industrial control cabinets and automation panels
• Telecommunications power distribution with intermediate DC bus
• Battery-backed or vehicle-mounted DC systems within input range
• Embedded equipment requiring 12V/10A supply on a DIN rail

How to use

Mount the converter on a standard DIN rail inside the control cabinet and make sure the unit is secured. Connect the DC input within the specified 33.6–67.2Vdc range, observing correct polarity and adequate wiring for the expected current. Connect the 12Vdc output to the load using cables sized for 10A. Verify connections before powering up and monitor output voltage at initial switch-on to confirm proper operation.

Recommendations

Install the device in a ventilated enclosure and avoid mounting near heat sources. Use appropriate fusing on the input and output lines, and follow local electrical codes. For installations in electrically noisy environments, consider additional filtering or transient protection upstream.
