Power module provides harsh environment reliability
A half-brick COTS AC/DC power module with an output voltage of 375V, the PFC-375, part of Astrodyne’s UniVerter Series, offers reliability in the most demanding applications. Suitable for aviation applications as well as other challenging thermal and shock vibration environments, this base-plated, potted module features Astrodyne’s Insulated Metal Substrate (IMS) construction.
Astrodyne’s UniVerter modules use a boost converter that incorporates a solid state series switch for active inrush and short circuit current limiting, as well as a way to provide over-temperature shutdown with automatic recovery.
This encapsulated 2.3x2.4x0.5” half brick power factor correction module has an input range of 85-265VAC, a frequency range of 47-880Hz and a power factor of 0.99.
Jerrold M Hornstein, Director of Business Development, Mil/Aero Market Segment, Astrodyne, said: “The 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, lower power alternative to our ¾ brick, 650W, PFC-650 module while offering the same performance characteristics.”
The PFC-375 comes in RoHS-compliant or SnPb solder versions and offers an operating temperature range of -55 to +100°C. Pricing starts at $350.72 per unit, and delivery is 10-12 weeks ARO.
