400W power supply is ruggedised for MIL applications

The 7602 is conformally coated in accordance with IPC-CC-830 and has been redesigned to meet the requirements of MIL-STD-461F surge test per MIL-STD-1399, withstand ESD to 8KV, has very low output ripple and noise figures, and high efficiency of greater than 80% at 115V AC and full load.

Supplied with nominal outputs of +5, +3.3 and ±12V DC, the power supply is fully compliant with the PICMG 2.11 power interface specification, incorporates the standard Positronic 47-pin connector and offers optional hot-swap, N+1 redundant connection and active load current share. The 7602 power supply features a 90-264V AC universal AC input voltage with active power factor correction, standard output voltages are 5V/50A, +3.3V/60A, +12V/7.5A and -12V/4A and custom variants are possible. All models can have an optional passive I2C bus, which can provide serial number, model number, revision number, and/or user defined data.

The Gresham 7602 Compact PCI power supply features advanced status and control functions including remote inhibit, output fail alarm, over temperature warning, output remote sense, optional single wire current share and front panel LEDs indicate outputs OK and any fault condition. The 7602 is RoHS compliant has an operating temperature range from -40 to +65ºC full load with 250LFM of airflow and MTBF is calculated as more than 250,000 hours minimum per RIAC-HDBK-217.
