CPCI power supplies available on short lead times

With worldwide universal AC input, active power factor correction and better than 81 per cent efficiency at 230VAC input, Gresham said system designers will appreciate its space-saving dimensions of 3U high by 8HP wide and 220mm depth.

The 250W cPCI power supply fully conforms to the accepted Compact PCI specifications and offers 'hot-swap' connection, output current sharing for N+1 redundant operation and requires no minimum load to function correctly.

Backplane connection is via the standard Positronic 47-pin PICMG 2.11 connector.

The power supply is fully safety-agency approved to UL, CSA and TUV, is CE marked and conducted EMC meets EN5022 class B and FCC-68, Part-15.

Standard output voltage configuration is 5VDC at 20A, 3.3VDC at 30A, +12VDC at 3A and -12VDC at 0.5A.

Input voltage is 'universal' from 85-264VAC over the frequency range 47-63Hz and a 48VDC input version is also available.

Full output power is available over a temperature range of -10C to +55C with 15CFM of cooling.

Additional standard features include: unlimited duration overload and short-circuit protection, over-voltage and over-temperature protection; load sensing on 5VDC and 3.3VDC outputs; 'enable', 'inhibit' and 'power good' signals; front-panel LEDs to indicate output and input power status; and I2C data bus for remote monitoring and control.
