The VPX-3U-AC115-3-C is a 3-Phase, 100-140 VrmsL-N, 47-800 Hz AC input, 28 Vdc output VPX power supply for critical military/aerospace applications. It delivers up to 750 W and is 91.5% efficient at 85°C (at card wedge locks). This Vita 62.1 compliant VPX is equipped with several features, including an integrated EMI filter, conduction cooling, low inrush, and over-voltage, under-voltage, short circuit and over-temperature protections. The VPX-3U-AC115-3-C comes standard with conformal coating and I2C communications.
