Overview
What it is
The MEAN WELL EDR-120-48 is a 120 W DIN rail power supply from the EDR-120 series (120 W Single Output Industrial DIN RAIL). It provides a 48 V DC output with up to 2.5 A of rated current.
What it is used for
DIN rail supplies clip onto a standard TS-35 rail inside control panels and electrical cabinets, a common way to power access controllers, PLCs, relays and sensors.
Key Specifications
- Output: 48 V, 2.5 A rated current, 120 W rated power.
- Output voltage adjustable over 48 to 55 V.
- Typical efficiency: 88.5%.
- Operating temperature: -20 to +60 °C (see derating curve in datasheet).
- Dimensions: 40 x 125.2 x 113.5 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.
