CompactPCI Power Supply offers 300 W power in 3U unit

CompactPCI Power Supply offers 300 W power in 3U unit

Compliant to PICMG 2.11 Power Interface Specification and fitted with Positronic 47 pin connector, cPCI power supplies are hot-swap and parallel redundant enabled. Power density allows up to 40 A to be drawn from +3.3 Vdc output and 30 A from +5 Vdc output @ 55[degrees]C. Available with 48 Vdc input or universal ac (90-264 Vac) input up to 440 Hz with active PFC, products feature OR-ing diodes, independent parallel converter topology, and 2 main outputs with remote sense.

300W maximum power in standard 3U x 8HP shelf space

Universal AC to 440Hz and 48VDC input versions

Ruggedised versions for MIL COTS applications

June 2005 – Gresham Power Electronics announce the introduction the latest addition to their market leading range of CompactPCI power supplies. Fully compliant to the PICMG 2.11 Power Interface Specification and fitted as standard with a Positronic 47 pin connector the new cPCI power supplies are hot-swap and parallel redundant enabled. Extra-high power density allows up to 40A to be drawn from the +3.3VDC output and 30A from the +5VDC output at 55[degrees]C.

Two input options are available, universal AC (90 – 264VAC) at up to 440Hz with active power factor correction and 48VDC. The two main outputs feature remote sense and all units include OR-ing diodes allowing single wire current sharing for increasing output power or n+1 redundant operation. The power supply has control signals for over-temperature, over voltage and over current protection as well as power-good and inhibit for systems integration. Input good, power fail and over temperature front panel LED indicators are also fitted. Full international safety agency approvals, UL, cUL and CE have been attained.

Very high efficiency and power density are achieved by employing independent parallel converter topology and state of the art synchronous rectification, low profile magnetics and a high degree of surface mount assembly. The 24VDC input version is qualified to UL1604 for operation in harsh and hazardous industrial environments. For military COTS and extreme industrial applications all models may be ruggedised and conformal coated with extended operating temperature range from -40[degrees]C to +85[degrees]C.

The new power supplies are industry standard size, 3U x 8HP, and have the customary +5VDC, +3.3VDC and +/-12VDC outputs. Continuing Gresham Power’s flexibility design philosophy non-standard outputs are available to special order with no NRE costs for OEM quantities.

Melanie O’Connor, General Sales Manager of Gresham comments, “Our CompactPCI products have been very successful in both standard and custom markets. We have found a growing requirement for more power in the 3U market as end users increase their system demands but are unwilling to move to the 6U form-factor. Our new 300W, 3U CompactPCI product give sour customers what they need and puts us ahead of the market.”

Typical applications for the new Gresham 300W cPCI products include; embedded computing, industrial systems, process control, security, telecom, etc.

Gresham Power has been involved in power conversion for nearly 50 years. Their Salisbury facility has fully approved design and manufacturing capabilities for commercial and military power products and also UPS. Gresham Power also provides European sales and application support for its sister companies, Telkoor and Digital Power who provide high power density switch mode power supplies and Compact PCI products respectively. Gresham also has a thriving distribution business enabling them to offer a “one stop shop” for power conversion products. The company’s website can be found on www.greshampower.com
