Overview

What it is

The MEAN WELL DDR-120C-48 is a 120 W DIN rail DC-DC converter from the DDR-120 series (120 W DIN Rail Type DC-DC Converter). It provides a 48 V DC output with up to 2.5 A of rated current.

What it is used for

DIN rail DC-DC converters convert one DC rail to another inside control panels.

Key Specifications

Output: 48 V, 2.5 A rated current, 120 W rated power.
Output voltage adjustable over 48 to 56 V.
Typical efficiency: 92%.
Operating temperature: -40 to +70 °C (see derating curve in datasheet).
Dimensions: 32 x 125.2 x 102 mm (W x H x D).

Buying considerations

Choose a rated current with headroom above the total load of the connected devices, and check the derating curve in the datasheet if the supply will run hot or at low input voltage. Other output voltages and power ratings in the same series are listed on this page.

Installation considerations

MEAN WELL treats this unit as a component to be installed inside final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring, safety and EMC details are in the official datasheet linked below.
