Description
The MORNSUN LM450-20B48 AC/DC Power Supply is a highly compact, open-frame enclosed switching power supply engineered for dependable, high-efficiency performance in demanding industrial, commercial, and medical environments. Operating seamlessly with a wide input voltage range of 90-264VAC or 127-370 VDC, this unit delivers an impressive power output of 250W under natural convection cooling and up to 450W with forced air cooling. Designed to withstand harsh thermal conditions, it functions reliably within an operating temperature range of -40°C to +70°C and supports elevations up to 5000 meters.
Equipped with an integrated active PFC (Power Factor Correction) function, this unit ensures high energy efficiency and power factor stability. It features comprehensive output protections—including short-circuit, over-current, over-voltage, and over-temperature safeguards—to protect connected equipment. Additionally, it provides advanced utility features such as a 5VDC standby output, a 12VDC fan supply, a power good signal, and remote sensing. Fully compliant with rigorous medical safety standards (2 x MOPP) and suitable for BF applications, the LM450-20B48 is an exceptional power solution for sensitive medical equipment, automation systems, and high-power electronics.
