XPm2020

The XPm2020 is a VITA 62-compliant 3U VPX power supply that 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. The XPm2020 also provides on-card MIL-STD-461E/F EMI filtering and optional on-card holdup capacitance, which provides 40 ms (120 W symmetrical load distribution) of holdup time.

The XPm2020 fits in a VITA 62-compliant 3U VPX 0.8 in. or 1.0 in. slot. Up to 8.3 A on 12 V, 22 A on 5 V, 20 A on 3.3 V (limited by the connector) can be supported on each rail, with 1 A on 3.3 V auxiliary and 1.5 A on +/-12 V auxiliary. The XPm2020 can provide a combined total output power of up to 300 W at maximum operating temperature.

The XPm2020 features a VITA 46.11 Tier 1 and Tier 2 Intelligent Platform Management Interface (IPMI) controller, which monitors board voltages and temperatures.
