Medical Power Supply 350W 12V Lrs-350-12 AC DC Switching Power Supply with Overload Protection

Product Description

Product Introduction

The LRS-350 series is a 350W single-output enclosed type power supply featuring a slim 30mm (1U) low-profile design. With AC input range selectable by switch (115VAC or 230VAC), the series offers output voltage options from 3.3V, 5V, 12V, 15V, 24V, 36V to 48V. Designed for industrial automation, control systems, mechanical and electrical equipment, this power supply delivers reliable performance in demanding environments.

Product Features

Wide Operating Range & Compact Design

Operates from -25°C to +70°C with full load. Withstands 300VAC surge input for 5 seconds and supports operating altitude up to 5000 meters. The 215×115×30mm (L×W×H) 1U form factor saves valuable cabinet space

Comprehensive Protection & High Reliability

High Efficiency with Low Standby Power

Equipped with short circuit, overload (110140% rated output power), over voltage, and over temperature protection. 100% full load burn-in test and 5G vibration resistance (10500Hz) guarantee long-term stability in harsh industrial conditions.

Delivers up to 89% efficiency with no-load power consumption below 0.75W, helping end systems meet global energy requirements. Built-in long-life fan with temperature-controlled ON-OFF operation ensures optimal cooling while minimizing noise
