XPm2222 3U VPX Power Supply

The XPm2222 is a VITA 62.0 form factor 3U VPX power supply. The XPm2222 takes in a MIL-STD-704A/E/F or MIL-STD-1275D 28 VDC input voltage and provides up to 260 W on 3.3 V, 5 V, and ±12 V at up to 87% efficiency. The XPm2222 also provides on-card MIL-STD-461F EMI filtering, MIL-STD-1275D transient suppression, and 10 ms of holdup time at 200 W output power.

The XPm2222 fits in a VITA 62-compliant 3U VPX 1.0 in. slot. Up to 16 A on 12 V, 0.5 A on -12 V, 15 A on 5 V, 12 A on 3.3 V, and 0.8 A on 3.3 V auxiliary can be supported on each rail, separately. The XPm2222 can provide a combined total output power of up to 260 W at maximum operating temperature.

The XPm2222 also features a VITA 46.11 Tier 1 and Tier 2 Intelligent Platform Management Interface (IPMI) controller which monitors input and output voltages and temperatures. In addition, the IPMI controller can enable/disable output power.
