The LM350-10Bxx Series: A Robust 350W Power Supply for Demanding Industrial Applications
When reliability under tough conditions is non-negotiable, your power supply must be a cornerstone of stability. The MORNSUN LM350-10Bxx(-Q) Series stands out as a high-performance, 350W enclosed AC/DC switching power supply designed for exactly these scenarios. Engineered for industrial environments, telecommunications, and outdoor controls, this series combines versatile input options, robust protection, and consistent power delivery in a rugged metal enclosure.
Engineered for Resilience and Versatility
The LM350-10Bxx series is built to tackle the unpredictable nature of industrial power grids and harsh operating conditions. Its defining feature is a selectable AC input range (90-132VAC / 180-264VAC), allowing for seamless global deployment. Uniquely, it also accepts a wide DC input (240-370VDC), making it an excellent choice for systems with battery backup or renewable energy sources.
To ensure continuous operation, it incorporates a comprehensive suite of self-recovering protection features, including output short circuit, over-current, over-voltage, and over-temperature protection. A built-in DC fan provides forced air cooling, enabling it to maintain full performance across an operating ambient temperature range of -30°C to +70°C and at altitudes up to 5000 meters. A simple LED indicator provides clear power-on status, and the design meets key international safety and EMC standards, including UL/IEC/EN62368, EN60335, and CISPR32.
