XPm2120

The XPm2120 is a VITA 62.0-compliant 3U VPX power supply that allocates 12 V 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. The XPm2120 also provides on-card MIL-STD-461E EMI filtering.

The XPm2120 fits in a VITA 62.0-compliant 3U VPX 0.8 in. or 1.0 in. slot. Up to 25 A on 12 V, 2 A on -12 V, 40 A on 5 V, 20 A on 3.3 V, and 4 A on 3.3 V Auxiliary can be supported on each rail, separately. The XPm2120 can provide a combined total output power of up to 300 W at maximum operating temperature. The XPm2120 also can be paired with another XPm2120 for load sharing on the 12 V rail.

The XPm2120 features a VITA 46.11 Tier 1 and Tier 2 Intelligent Platform Management Interface (IPMI) controller which monitors board voltages and temperatures.
