Description
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 input is protected by a transient suppressor (varistor) 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.
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 or ORing 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 **s 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.
