Half-brick front end module for use in demanding space-constrained applications

Designers looking for a power module for tight fits in military and commercial aviation applications can consider the PFC-375 from Astrodyne Power Supplies, a half-brick COTS AC/DC power module with an output voltage of 375 V.

Designers looking for a power module for tight fits in military and commercial aviation applications can consider the PFC-375 from Astrodyne Power Supplies, a half-brick COTS AC/DC power module with an output voltage of 375 V. The module is part of Astrodyne’s UniVerter Series of products, which use a boost converter that integrates a solid-state series switch for active inrush and short-circuit current limiting; the modules also feature over-temperature shutdown with automatic recovery. Aimed at use in military and commercial aviation applications and other environments with tough thermal and shock requirements, the PFC-375 base-plated, potted module features Astrodyne’s proprietary insulated metal substrate construction. According to the company, the module is compliant with MIL-STD-704 transient and MIL-STD-461 and RTCA DO-160 total harmonic distortion requirements. The encapsulated 2.3-inch x 2.4-inch x 0.5-inch 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 °C to +100 °C
