VPX power supply with long holdup capabilities unveiled by SynQor

BOXBOROUGH, Mass. SynQor, Inc. announced its new universal 85 to 264 Vrms AC input VPX power supply with long holdup capabilities compliant to MIL-STD-704F for critical military, aerospace, and shipboard applications. The 3U VPX power supply is designed to meet VITA 62 standards and is intended to allow designers in the defense markets to power their VITA 62 chassis with the latest VPX technology.

According to SynQor, the long holdup VPX-3U-ACUNV universal AC input power supply delivers 300 W with an efficiency of 84% and has been designed to meet MIL-704(B-F) input dropout transients. It is intended to be able to operate at wedge-lock temperatures as high as 85°C with full output power.

The company claims that the VPX can be powered over a dual frequency range, 47 to 63 Hz and 360 to 800 Hz, with a power factor of 0.99 at 50/60 Hz and 0.97 at 400 Hz. The power module is equipped with features including an integrated EMI filter, conduction cooling, six output voltages, and voltage protections.

It has an optional I2C communications feature (IPMI, PMBus, VITA 46.11) and the VS1 (+12 V), VS2 (+3.3 V), and the VS3 (+5 V) outputs can be load shared on a standard VITA 62 chassis.
