Description
Mean Well Power Supply – 5V 300W – Product Details
The Mean Well Power Supply – 5V 300W is a compact and efficient 300W single-output enclosed switching power supply designed for versatile applications across industrial automation, mechanical systems, and electronic equipment. With a 5V DC output and a robust 60A output current, it provides reliable power delivery with high precision and stability.
Key features include its universal AC input range of 90-264VAC (selectable by switch), forced air cooling by built-in DC fan, and compliance with international safety and EMC standards such as IEC/UL 62368-1. Its lightweight and low-profile design (30mm height) makes it suitable for installations with space constraints.
The LRS-350-5 is built for durability and performance, featuring protections against short circuits, overload, overvoltage, and over-temperature. It ensures safe operation with low no-load power consumption (<0.75W) and achieves an efficiency of up to 83.5%, reducing energy costs and heat generation.
