Product information

Description

The MEAN WELL DDR-120B-48 is an ultra-slim industrial DC-DC DIN-rail converter designed for applications requiring a regulated 48 Vdc output from a wide input range of 16.8–33.6 Vdc. With a rated output of 48 V at 2.5 A (120 W) in a compact module, it fits standard DIN-rail installations and complies with RoHS requirements.

Advantages

Compact DIN-rail housing with a slim 32 mm width conserves panel space while delivering up to 120 W output. The converter accepts a wide input voltage range, allowing compatibility with various battery and intermediate bus systems. Its industrial design supports reliable performance in control cabinets and automation equipment.

How to use

Mount the DDR-120B-48 on a standard DIN rail inside the control cabinet.
