conical-340-03-2014SynQor has announced the release of its PFCQor module, a power factor correction building block for AC-DC power conversion.When the PFCQor is used with SynQor’s AC line filter, a hold-up capacitor and SynQor’s high efficiency DC-DC converters, it draws a nearly perfect sinusoidal current (PF>0,99) from a single phase AC input and provides a complete front-end system that complies with EN55011, EN55022, EN61000 and FCC regulations. The PFCU390HPC delivers 700 W of output power in an industry standard half-brick package (6,35 x 6,35 x 1,27 cm) while achieving a efficiency as high as 96%.

The module accepts universal input voltage range of 85 – 264 Vrms input and operates in both the 45 – 65 Hz and 360 – 800 Hz frequency ranges. Offered in a fully encased and ruggedised package, the PFCU390HPC can operate from -40C to +100C on its baseplate and is said to be perfectly suited for harsh environments seen in many industrial, instrumentation and transportation applications that demand a low profile, extended temperature operation in a small space.

The feature-rich PFCU390HPC provides serial control inputs and outputs such as load enable, clock synchronisation, output current monitoring and active current sharing for higher power requirements. Protection features include input under/over-voltage protection, output over-voltage protection, output current limit and thermal shutdown.
