500W Slim Type Fanless AC/DC Enclosed SMPS, the ideal choice in harsh working environments – LMF500-23BxxUH

LMF500-23BxxUH series is one of Mornsun's fanless semi-potted AC/DC enclosed power supplies. With an universal input range that supports both AC and DC input, it features high efficiency, high reliability, and high PF value with competitive cost. Safety insulation and fanless design make it ideal for industrial and outdoor harsh environments.

 

These products offer excellent EMC performance and meet EN/UL62368, EN61558, EN60335, and GB4943 standards, which can be widely used in areas of industrial, lighting, electricity, security, telecommunication, smart home, etc.

 

Advantages

Ultra-slim shape, High power density

232mm*81mm*31mm, power density up to 14.1W/inch³

 

Wide applied range

a. Comply with EN/UL62368, EN61558, EN60335, GB4943 standards

b. Universal input voltage range: 85-305VAC

c. Operating temperature range: -40℃ to +85℃

d. Support side installation

e. PF>0.95 (Full load at 230VAC)

 

High reliability

Within 70℃, altitude below 2000m and natural air cooling environment, 3-year warranty;

Within 50℃, altitude below 5000m and natural air cooling environment, 5-year warranty.

b. Output short circuit, over-current, over-voltage, over-temperature protections

c. Leakage current < 0.75mA/277VAC.

d. Work without fan at full load

e. Adopting the semi-potted design to improve the reliability of the power supply in high-humidity, dusty, and other harsh environments, is better than the one with conformal coating on each side.
