Ruggedised 400W PCI PSU tolerates harsh environments

June 03, 2014 // By Graham Prophet
Gresham Power Electronics has a Compact PCI power supply ruggedised for MIL and industrial applications, that includes conformal coating for protection, and an operating temperature range -40ºC to +65ºC.

The 7602 is a 6U AC/DC cPCI PSU which 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 kV, has very low output ripple and noise figures, and high efficiency of >80% at 115 VAC and full load.

Supplied with nominal outputs of +5, +3.3 and ±12VDC the supply can be factory modified to a wide range of output voltage configurations on all four outputs or it could be factory set to be a single output version of 12 to 48 VDC rated at 600W.

It 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. 7602 has a 90–264VAC 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 I 2C bus, which can provide serial number, model number, revision number, and/or user-defined data.

There are 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. -40ºC to +65ºC full load operation is with 250LFM of airflow and MTBF is calculated as >250,000 hours minimum per RIAC-HDBK-217
