Gresham's 600W Compact PCI Power Supply


electronica 2010, Hall B2, Stand 349

At this year's electronica, Gresham Power Electronics, the Salisbury based MIL and Commercial power conversion specialist, will be demonstrating how their 6U 600W cPCI power supply can cost effectively replace all other 6U products of lower output power. Jake Moir, Managing Director of Gresham Power Electronics, explains; "We have invested extensively in ensuring our 6U, 600W CompactPCI power supply offers leading edge performance. Our steadily increasing sales, advanced design and efficient manufacturing processes mean that we can now offer a 600 watt unit competitively priced against other manufacturers 400 to 550 watt units. This allows our customers to reduce the complexity of their own inventory, saving costs, simplifying system assembly and service support. Having 600 watts of power available in less demanding applications insures against output power load surges and increases reliability. In effect our customers can have up to 30% of additional bonus power, at no extra cost." The 600W Gresham cPCI-6U-600 has been developed to respond to growing market demands for ever increasing power from the 6U cPCI footprint. 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. 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, making them ideal for use in almost any application. Standard output voltages are 5V/65A +3.3V/80A +12V/12A -12V/1.5A and custom variants are possible. All models have a monitor and control (M&C) system based on an intelligent I2C bus. This system provides comprehensive remote status monitoring and control functionalities. Very high efficiency and power density result from the use of advanced component and circuit technologies, such as synchronous rectification, low profile transformers and SMT components. 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. The Gresham cPCI-6U-600 family are all RoHS compliant, 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, CE Mark (LVD) and EN55022 Level A. Operating temperature range is -5C to +55°C with de-rating at 2.5%/°C up to +70°C, cooling requirements are 400LFM of airflow and MTBF is calculated as >400,000 Hours per Belcore 332 issue 6. Gresham Power compactPCI products are suitable for advanced multi-media applications, industrial, communications and broadcast systems. Gresham also manufactures a complete range of OEM power supplies, hot-swap power shelves and products for telecoms, medical, industrial and commercial applications as well as static frequency converters, DC UPS, distributed power systems and DC:AC inverters for Naval Defense systems.
