DESCRIPTION
The cPCI-D-3U-300C is a high-reliability, 300W, continu-
ous power, 3Ux8HP CompactPCI™ power supply devel-
oped 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 ap-
provals to UL60950 and EN60950, EMI compliance to
Class B FCC and EN55022 standards, the cPCI-D-3U-
300C was designed with globally-deployed systems in
mind. Additional features include remote sense compen-
sation, 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.

Notes:
1. Total power limited to 300W.
2. Maximum combined power from V1 & V3 not to exceed 185W. Maximum combined power for V2 & V4 not to exceed 140W.
3. Maximum voltage compensation for cable losses .
4. Tolerance applicable up to 6 parallel units. Single wire current share on V1 & V2 for 50% to 100% load.
5. Measured across 1μF ceramic capacitor and 120μF electrolytic capacitor.
6. Automatic recovery upon removal of overload condition.
