DESCRIPTION
The cPCI-D-3U-300C is a high-reliability, 300W, continuous power, 3Ux8HP CompactPCI™ power supply developed for chassis’ with airflows as low as 250lfm. The use
of 2 converters operating in parallel for the 3.3V and the
5V outputs enables maximum current draw on the two
outputs simultaneously. Compliant with the PICMG 2.11
standard.
With a widerange input of 36-72Vdc, safety agency approvals to UL60950 and EN60950, EMI compliance to
Class B FCC and EN55022 standards, the cPCI-D-3U300C was designed with globally-deployed systems in
mind. Additional features include remote sense compensation, unit enable control (EN#), output inhibit control
(INH#), output fault signal (FAL#), and thermal warning
signal (DEG#). LEDs are provided for visual indication of
input power presence and output fault condition.
