COTS Power Factor Correction Front End ModuleDecember 22, 2014 by Jeff Shepard
Astrodyne Corporation now offers a half-brick COTS ac-dc power module with an output voltage of 375Vdc. The PFC-375, part of Astrodyne's UniVerter Series, offers high reliability in the most demanding applications. Suited for use in military and commercial aviation applications and other challenging thermal and shock vibration environments this new base-plated, potted module features Astrodyne's proprietary Insulated Metal Substrate (IMS) construction.
Jerrold M Hornstein, director of business development for Astrodyneâ€™s mil/aero market segment, said, â€œThe PFC-375 offers high power factor, compliance with MIL STD 704 transient and MIL STD 461 and RTCA DO-160 total harmonic distortion requirements. It provides a smaller sized, lower power alternative to our three-quater brick, 650W, PFC-650 module while offering the same performance characteristics.â€
This encapsulated 2.3â€ x 2.4â€ x 0.5â€ half brick power factor correction module has an input range of 85- to 265-Vac, a frequency range of 47- to 880-Hz and a power factor of 0.99. The PFC-375 comes in RoHS compliant or SnPb solder versions and offers an operating temperature range of -55 to +100 degrees C. Pricing for the PFC-375 starts at $350.72 per unit. Delivery is 10-12 weeks ARO.
