300-W 3U CompactPCI power supplies target ruggedised industrial and marine applications
June 11, 2012 // Paul Buckley
Gresham Power Electronics has launched ruggedised versions of the companyís 300 W, 3U cPCI power supply.
Available in 24 VDC, 48 VDC and universal AC input versions the ruggedised power supply range has a conformal coating for extreme industrial, MIL/COTS and marine applications.
Fully compliant to the PICMG 2.11 Power Interface Specification the AC 3U 300R provides 300W maximum power in standard 3U x 8HP shelf space with interconnection via a Positronic 47 pin connector. The new cPCI power supplies are hot-swap and parallel redundant enabled. Extra-high power density allows up to 40 A to be drawn from the +3.3 VDC output and 30A from the +5 VDC output at 55ºC.
The two main outputs feature remote sense and 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.
The new Gresham ruggedised CompactPCI power supplies are industry standard size, 3U x 8HP, and have the customary +5 VDC, +3.3 VDC and ±12 VDC outputs. The AC input model has a universal input from 90–264 VAC and active power factor correction.
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.
Gresham Power offer a very wide range of 24 VDC, 48 VDC and AC input cPCI products including the market leading CPCI-AC-6U-650 6U 650 W output model. The DC input versions of cPCI power supplies are suitable for vehicle and ground station installations while the AC models meet conventional rack based requirements.
