The LRS-350 is a 350W single-output power supply unit from Winston Electric, featuring a low-profile design of only 30mm in height. It supports an input range of 115VAC or 230VAC, selectable via a switch, and offers a wide range of output voltages including 3.3V, 4.2V, 5V, 12V, 15V, 24V, 36V, and 48V.

The LRS-350 series provides efficiency up to 89% and is equipped with a long-life internal fan for forced air cooling, allowing it to operate at full load under temperatures ranging from -25°C to +70°C 。

Key Features:

Low height of only 30mm, making it suitable for applications where space is limited.
Wide operating temperature range.
Full range AC input with a switch selection for different voltage regions.
Protection features include short circuit, over-load, over-voltage, and over-temperature protection.
Capable of withstanding 5G vibrations, making it suitable for environments with mechanical stress.
Fan on/off control for applications that require it.
High efficiency and long life, with a 3-year warranty.
