PCB AC-DC converters

Cosel has introduced the LFA series of PCB AC-DC converters, an upgraded version of the company’s simple PCB single-output LDA series, to meet increasing demands for miniaturisation and low cost.

The company has released five versions, from 10 to 75 W, with three further 100, 150 and 300 W versions planned for later release.

The LFA series has a smaller footprint than the LDA. Universal input includes 29 options such as output control, low leakage and chassis cover.

Features includes: small and compact PCB construction; built-in inrush current, overcurrent and overvoltage protection circuits; harmonic attenuator (complies with IEC61000-3-2); universal input, 85-264 VAC; power factor correction (LFA50F, 75F); built-in reducing standby power circuit (LFA10F, 15F).
