The LM50-20B48 is a compact, 52.8W AC-DC Switch Mode Power Supply (SMPS) housed in a small outline metal case. This power supply is designed to provide a highly reliable, cost-effective, and energy-efficient solution for systems requiring a stable 48V power source, particularly in industrial, LED, security, and telecommunications applications.
A key feature is its universal and ultra-wide input voltage range of 85 ~ 264VAC and 120 ~ 370VDC (using the more conservative range from the features list, though the product title suggests a wider range). This broad input capability allows the module to be used globally and provides high resilience to fluctuations in the input power source. The SMPS delivers a single, regulated output of 48VDC with a current capacity of 1.1 Amperes, providing a stable and powerful source for systems requiring 48V power.
The LM50-20B48 is built for reliability, featuring a wide operating ambient temperature range of -30 to +70 . It boasts high efficiency and low standby power consumption, contributing to energy savings and reduced heat generation. Safety is paramount, with a high I/O isolation test voltage of 4000VAC and compliance with numerous safety and EMC standards, including IEC/UL/EN62368 and CISPR32/EN55032. The unit features terminal block termination for secure and easy wiring. Comprehensive protection features, including output short circuit, over-current, and over-voltage protection, ensure the longevity and safety of both the power supply and the connected equipment.
