The LM350-10B48 is a high-power, 350W AC-DC Switch Mode Power Supply (SMPS) housed in a small outline metal case. This power supply is engineered for demanding industrial and commercial applications, offering a cost-effective, energy-efficient, and highly reliable solution for systems requiring a stable 48V power source, common in telecommunications and industrial control.
A key feature is its selectable AC input range of 90 - 132VAC / 180 - 264VAC (via a switch) and a DC input range of 240 - 370VDC. This flexibility allows the unit to be adapted to various power systems globally. The SMPS delivers a single, regulated output of 48VDC with a high current capacity of 7.3 Amperes, providing a powerful source for high-current 48V systems.
The LM350-10B48 is built for continuous, high-power operation, featuring a wide operating ambient temperature range of -30 to +70 . To manage the heat generated by its high output, it includes a built-in DC fan for active cooling. It boasts high efficiency and ultra-low standby power consumption (< 0.75W @ 230VAC), contributing to energy savings. Safety is paramount, with a high I/O isolation test voltage of 4000VAC (implied by the series name) and compliance with numerous safety and EMC standards. The unit features terminal block termination for secure and easy wiring. Comprehensive protection features, including output short circuit, over-current, over-voltage, and over-temperature protection, ensure the longevity and safety of both the power supply and the connected equipment.
