LFA Series, Single Output, 10 to 75 W
LFA switch mode power supplies (SMPS) from Cosel are incredibly compact, taking up 38% less volume than the LDA series. With a field failure rate of less than 0.01%, LFA switch mode power supplies are highly reliable at an affordable price. Featuring a universal input of 85 V ac to 264 V ac, LFA series SMPS are fully regulated and have a fully isolated input/output.
Features and Benefits:
Single output
Harmonic attenuator
Overcurrent, inrush current, and overvoltage protection circuits are built in
Convection cooling
Synchronous rectification enables high efficiency
Power factor correction for LFA50F to LFA300F models
LFA10F and LFA15F modules have a built-in reducing standby power circuit
Product Applications:
These switch mode power supplies are designed for use in applications where space is limited.
