XPm2120 MIL-STD Power Supply


Overview

MIL-STD-704, 28 V Input to ±12 V, 5 V, and 3.3 V Output, VITA 62.0, 3U VPX Power Supply with Integrated MIL-STD-461E Filtering

The XPm2120 from Extreme Engineering Solutions (X-ES) is a VITA 62.0-compliant 3U VPX power supply, providing on-card MIL-STD-461E EMI filtering.

12 V is allocated as the primary distribution rail across the backplane to the payload modules. The XPm2120 takes in a MIL-STD-704 28 VDC input voltage and provides up to 300 W on 3.3 V, 5 V, and ±12 V at up to 90% efficiency.
