The CPA and CPD Series are highly reliable power supplies
for CompactPCI® systems, which are increasingly used in
communications, industrial, military, aerospace, and other
applications. These power supplies offer high power density
in plug-in modules that meet the requirements of the
PICMG® power interface specification for CompactPCI®
systems.

The converters use the patented EDGETM technology and
provide important advantages such as flexible output
power, extremely high efficiency, excellent reliability, full
input-to-output isolation, negligible inrush current, hot-swap
capability, soft start, and overtemperature protection.
The inputs are protected against surges and transients
occurring on the source lines and cover an operating input
voltage range from either 90 to 264 VAC or 36 to 75 VDC.
Voltage suppressor diodes protect the input against
overvoltage.

The outputs are protected against continuous overload,
open-circuit, and short-circuit. Full n+1 redundant operating
mode is made possible by integrated ORing FETs/diodes.
When several converters are connected in parallel, a
single-wire connection between converters ensures current
sharing.

The converters are designed as two or three separate
forward converters with fixed switching frequency and
synchronous rectifiers at their output.
LEDs on the front panel and various warning signals display
the status of the converter. The aluminum case acts as a
heat sink and as an RFI shield. It is designed for vertical
insertion into 19" rack systems, but it can also be mounted
in any other position, as long as the necessary airflow is
ensured. The connector is a 47-pin type from Positronic or
similar.

Several options are available to meet different
requirements.
