100W Universal Input AC-DCs with Active PFC

October 13, 2019 by Paul Shepard

Mornsun has released a new enclosed ac-dc power supply series, the LMF100-20Bxx, with active power factor correction. The LMF100-20Bxx series features universal input voltage range of 85- to 264-Vac, accepts ac or dc input and has a power factor up to 0.98.

In addition, its emissions meet CISPR32 CLASS B without extra components. The new series also meets IEC/EN/UL62368, EN60335, GB4943 safety standards.

These single-output 100W ac-dc power supplies are offered with standard output voltages of 5-, 12-, 15-, 24-, and 48-Vdc. Efficiency ranges from 86% to 88%, depending on the output voltage.

Protections of output short circuit, over-current, over-voltage, over-temperature are included. MTBF is more than 300,000 hours and the dimensions are 10% smaller than conventional products, which make this series suited for industrial, civil, smart home, and smart building applications.

The LMF100-20Bxx series is expected to find wide use in applications of industrial automation machinery, industrial control system, mechanical and electrical equipment, instrumentation, intelligent building, household appliances, and so on.
