Overview

What it is

The MEAN WELL EPS-45-7.5 is a 40.5 W PCB mount power supply from the EPS-45 series (45 W Single Output Switching Power Supply). It provides a 7.5 V DC output with up to 5.4 A of rated current.

What it is used for

PCB mount modules are soldered onto a circuit board to give the board its own isolated low voltage supply.

Key Specifications

Input range: 90 to 264 V AC, 127 to 370 V DC [DC input operation possible by connecting AC/N(+), AC/L(-)].
Output: 7.5 V, 5.4 A rated current, 40.5 W rated power.
Output voltage adjustable over 7.13 to 8.25 V.
Typical efficiency: 84%.
Operating temperature: -30 to +70 °C (Refer to output load derating curve).
Dimensions: PCB:101.6 x 50.8 x 29 mm (L x W x H); with optional CASE:103.4 x 62 x 37 mm (L x W x H).

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.
