720W Power Factor Correction Module From Powersolve

The AIT02ZPFC features a universal input that accepts any voltage in the range 85 to 264 VAC at any frequency from 47 to 63 Hz and from 360 to 800 Hz. It has a 2.4 x 3.5in footprint and a mounting height of just 0.55in, making it ideal for space-constrained applications

When supplied with a 230VAC input, the AIT02ZPFC has a typical power conversion efficiency of 93%, can deliver up to 1.83A at 393VDC and achieves a power density in excess of 155W in³. The module uses active power factor correction to minimise input harmonic current distortion and ensure compliance with the RTCA/DO-160D avionics standard at 115VAC at full load, and EN61000-3-2.

A number of built-in control and monitoring functions make the AIT02ZPFC module easy to integrate within a system. Remote-enable and temperature monitoring functions are provided as standard, and the output voltage can be adjusted from 79% to 100% of nominal via a single control pin. Inrush current is limited by an external resistor.

AIT02ZPFC modules are fully encapsulated and have an aluminum baseplate for conduction cooling. They have no minimum load requirement and operate over a wide baseplate temperature range of -20 to +100ºC. Input-to-baseplate and output-to-baseplate isolation is rated at 2700 VDC, and leakage current is held to less than 3 ma at 800 Hz input frequency. The modules are fully protected against over-voltage and over-temperature conditions and carry a full set of international safety agency approvals, including EN60950 TUV and UL/cUL60950.
