0.98 Power Factor!100WActive PFC Enclosed Switching Power Supply LMF100-20Bxx Series

MORNSUN released a new enclosed switching power supply series LMF100-20Bxx with active PFC(Power factor correction). The LMF100-20Bxx series features universal input voltage range of 85-264Vac, accepts AC or DC input and the PF(Power factor) is up to 0.98. In addition, its emissions meets CISPR32 CLASS B without extra components. The new series also meets IEC/EN/UL62368, EN60335, GB4943 safety standards. Protections of output short circuit, over-current, over-voltage, over-temperature are included. MTBF is more than 300,000 h and the dimension is 10% smaller than conventional products, which make this series ideal for industrial, civil, smart home, smart building applications.


Widely used in applications of industrial automation machinery, industrial control system, mechanical and electrical equipment, instrumentation, intelligent building, household appliance, etc.

Typical application: Numerical control machine tools
