Overview

What it is

The MEAN WELL LOP-500-12 is a 499.2 W PCB mount power supply from the LOP-500 series (500 W 5″×3″ Low Profile Open Frame Power Supply). It provides a 12 V DC output.

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: 80 to 264 V AC, 113 to 370 V DC.
Output: 12 V, 499.2 W rated power.
Output voltage adjustable over 11.4 to 12.6 V.
Typical efficiency: 93.5%.
Operating temperature: -40 to +80 °C (see derating curve in datasheet).

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.
