New 100W and 150W enclosed power supply with active PFC

Mornsun released new enclosed switching power supply series LMF100-20Bxx and LMF150-20bxx with active PFC (power factor correction). The LMF100-20Bxx and LFM150-20Bxx series feature universal input voltage range of 85 – 264Vac, accepts AC or DC input and the PF (power factor) is up to 0,98. Also, its emissions meet CISPR32 CLASS B without extra components.

The new series meets IEC/EN/UL62368, EN60335, GB4943 safety standard. 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 and smart building applications.


The power supplies are being used widely in applications of

  • industrial automation machinery
  • industrial control systems
  • mechanical and electrical equipment
  • instrumentation
  • intelligent building
  • household appliance
