Compact PCI power supply reduces costs

According to the company, having 600W of power available in less demanding applications can provide up to 30 per cent of additional bonus power compared to a conventional 400W, at no extra cost, protecting against output load power surges and increasing system reliability.

The Gresham cPCI-6U-600 units are all RoHS compliant, have advanced status and control functions including remote inhibit, output fail alarm, over-temperature warning, output remote sense, single-wire current share and front-panel LEDs indicate outputs OK and any fault condition.

They are fully compliant with the PICMG 2.11 power interface specification, incorporate the standard Positronic 47-pin connector and offer hot-swap, N+1 redundant connection and active load current share.

Compact PCI power supplies from Gresham power may also be made more rugged to special order.

These cPCI power supplies incorporate active power factor correction, an 85-264VAC universal AC input voltage or DC input covering a range from 36-72VDC.

Standard output voltages are 5V/70A, +3.3V/70A, +12V/7A, -12V/1.5A and custom variants are possible.

All models have a monitor and control system based on an intelligent IC bus providing comprehensive remote status monitoring and control functionalities.

Full international safety agency approvals are held, including UL/cUL60950, EN60950, CE Mark (LVD) and EN55022 Level B (with external filter).

Operating temperature range is -5 to +55C with de-rating at 2.5 up to 71C, cooling requirements are 300LFM of airflow and MTBF is calculated as >400,000 hours per belcore 332 issue 6.
