Information about MEAN WELL EPS-65-3.3

The MEAN WELL EPS-65-3.3 is a compact 40W industrial switching power supply featuring a 4" x 2" footprint, available as a standard PCB-type open frame or with an optional enclosed cover (-C) and L-bracket. Designed to meet strict energy standards, it accepts a universal AC input range and maintains a low no-load power consumption of under 0.3 W.

Key features include reliable fanless free air convection cooling across a wide operational temperature range of −30 °C to +70 °C, an onboard LED power indicator, and a voltage adjustment trimmer ranging from 3.14 to 3.6 V DC. Built-in protections against short circuits, overloads (hiccup mode), and overvoltage ensure maximum reliability for industrial equipment, factory automation, and mechanical applications.
