Power Supply

600W Compact PCI Power Supply responds to customer demands
Class leading high power density gives users more value for money


Gresham Power Electronics has introduced the latest addition to its very successful Compact PCI power supply family, the cPCI-6U-600. By continuing to push the boundaries of high efficiency, high power density power supply design Gresham are responding to growing market demands for ever increasing power from the 6U cPCI footprint.

Emerging communications, broadcast and advanced multi-media applications require increasing amounts of power which until now has meant using multiple power supplies connected in parallel. By delivering 600W in the standard cPCI package users can free-up more rack space for revenue earning electronics.

Jake Moir, Managing Director of Gresham Power Electronics, comments; “In these challenging times we continue to seek to offer our customers greater value for money and products which allow them to maximise their own sales revenues. Greater power density in the standard cPCI package frees up space for increased functionality in the end product adding value for our customers. Employing the latest components and topologies ensures we do not sacrifice quality or reliability while increasing our market opportunities.”

Their complete range of cPCI products is fully compliant to PICMG 2.11 and offer hot-swap, N+1 redundant connection and active load current share. AC input versions are power factor corrected and have a universal 90-264VAC, 47-63 Hz input range, a 48VDC input version is also available which operates over the range 36-72VDC. Standard output voltages are 5V/65A +3.3V/80A +12V/12A -12V/1.5A and custom variants are possible.

This family of products are all RoHS compliant, feature ruggedised construction as standard and 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.

Full international safety agency approvals are held including UL/cUL60950, EN60950, CE Mark (LVD) and EN55022 Level B. Operating temperature range is -5C to +55°C with de-rating at 2.5%/°C up to +71°C, cooling requirements are 400LFM of airflow and MTBF is calculated as >400,000 Hours per Belcore 332 issue 6.

Gresham Power’s cPCI product range represents the industry's leading cPCI AC/DC power supplies, delivering from 350 to 600W of continuous power. Gresham Power’s unique design uses two converters in parallel, one for the +3.3V and the other for the +5V. This design provides the flexibility for determining individual load requirements for each output independently enabling full load currents to be drawn.
