Emerson Network Power Debuts AIT02ZPFC Power Factor Correction Module

Emerson Network Power, a business of Emerson (NYSE: EMR), has launched a 720 watt power factor correction module that has a 2.4 x 3.5 inch footprint and a mounting height of just 0.55 inch, making it ideal for space-constrained applications. The new AIT02ZPFC module 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.

The AIT02ZPFC module presents a near unity power factor to the incoming power line, and generates a typical output of 393 Vdc, which is intended for feeding to one or more high voltage dc-dc converters for further down-conversion to the low voltages required by the application. Emerson Network Power produces a number of compatible high voltage half-brick and full-brick dc-dc converters, with outputs ranging from 1.8 to 48 Vdc. This fully modular approach enables users to build complete high performance, low profile ac-dc power supplies with minimal non-recurring engineering costs and fast turnaround.

Emerson Network Power AIT02ZPFC low profile power factor correction moduleWhen fed with a 230 Vac input, the AIT02ZPFC module has a typical power conversion efficiency of 93%; it can deliver up to 1.83 A @ 393 Vdc and achieves a power density in excess of 155 watts per cubic inch. The module uses active power factor correction to minimise input harmonic current distortion and ensure compliance with the RTCA/DO-160D avionics standard at 115 Vac 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 +100 degrees Celsius. Input-to-baseplate and output-to-baseplate isolation is rated at 2,700 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.

Emerson Network Power’s AIT02ZPFC modules are available for immediate delivery, and the standard lead-time for quantity orders is 8 weeks. Pricing in 100-piece quantities is $98 US.
