Mornsun's LBH300-138xx: High-Efficiency Half-Brick Power Supply for Telecom Environments


MORNSUN introduced the LBH300-138xx as part of its AC/DC BRICK power supplies LBH series, focusing on high-efficiency power supply within a half-brick package, intended mainly for telecom applications. This power supply suits industries facing harsh environments, temperature fluctuations, and space constraints, finding relevance in wireless tech, instrumentation testing, servers, computers, and semiconductor fields. Notable features include a wide input voltage range (85-305VAC), extensive protection measures, low THD, AUX auxiliary power support, ENA remote control, and a 5-year warranty. 

It functions within a wide temperature range (-40°C to +100°C), adheres to industry standards, and provides various protection features like input under voltage, over temperature, output over voltage/current/short circuit protection. The series is built for reliability with a 3000 VAC isolation voltage, suitable for diverse power supply scenarios such as industrial control, data communication, network communication, servers, semiconductor equipment, distributed power supply systems, on-board and marine systems.
