SynQor announced its new universal 85 to 264 Vrms AC-input VPX power supply for critical military, aerospace and shipboard applications. This 6U VPX power supply, designed to meet VITA 46 standards, allows designers in the defence markets to power their VITA 62 chassis with the latest flexible, efficient and reliable VPX technology.
The power supply delivers 630 W with an efficiency of 84% at 70°C (at card wedge locks). It is able to operate at wedge lock temperatures as high as 85°C with derated output power. 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 several features: integrated EMI filter, conduction cooling, five output voltages, over-voltage, under-voltage, short circuit and over-temperature protections. It has an optional I2C communications (IPMI, PMBus, VITA 46.11) feature The VS1/VS2 (+12 V), VS3 (+5 V) and the +3,3 VAUX outputs can be load shared on a standard VITA 62 chassis. It has been designed for the most demanding military applications. The VPX power supply unit meets VITA 46, VITA 47, VITA 62, MIL-STD-461F, MIL-STD-704 (B-F), and MIL-STD-810G standards.
