Description
The 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 Compact-
PCI
®
systems.
The converters use the patented EDGE
TM
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
input voltage range from 36 VDC up to 75 VDC. The
outputs have continuous overload, open-circuit, and
short-circuit protection. LEDs on the front panel, a
temperature warning signal, and a fail signal indicate the
status of the power supply. Voltage suppressor diodes
protect the input against overvoltage. Full n+1 redundant
operating mode is made 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 separate forward converters with synchronous
rectifiers at the outputs. The switching frequency is fixed at
approx. 135 kHz.
The aluminium case acts as a heat sink and as RFI shield.
It is particularly suitable for vertical mounting in 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.
