C&D Technologies Debuts cPCI420DC Power Supply

July 10, 2002 by Jeff Shepard

C&D Technologies Inc. (Tucson, AZ) announced its new cPCI420DC CompactPCI® dc power supply, which is a hot-swap unit in a standard 6U x 8HP form factor developed for high-availability telecommunications applications. Delivering 420W of continuous output power, the cPCI420DC has no minimum load requirements and supports the standard PCI output voltages of +5V, +3.3V, +12V and -12V. Active current sharing and internal OR-ing diodes support high-availability applications that require reliable, hot-swap performance and N+1 redundant configurations. In addition, the use of output-isolation diodes rather than FETs ensures true fault tolerance.

The new power supply can accommodate a wide input-voltage range of 36Vdc to 72Vdc. The supply is completely self-protecting, with overload protection on each output and over-voltage protection on the low-voltage outputs. In addition, the cPCI420DC features a

power limit and thermal switches for the "degrade" warning signal and thermal shutdown. Automatic recovery allows the unit to become operational once conditions return to normal. A red-fault indicator LED identifies if output voltages are outside of specification, while a green-power LED

indicates that the input voltage exceeds the minimum requirements.

Suitable for worldwide use, the cPCI420DC power supply is approved to UL1950, CSA950 and EN60950 safety standards. The cPCI420DC power supply is priced at $359 for 1,000 units.
