DESCRIPTION
The cPCI420 is a high-reliability, 420W, 6Ux8HP
CompactPCI™ power supply operating from widerange
48Vdc-input. Equipped with the 47-pin I/O connector
option, these units are fully compliant with the PICMG
2.11 R1.0 Power Interface Specification as well as the
underlying CompactPCI™ standards.
ORing diodes and active current sharing allow the
cPCI420 to be operated in N+n parallel-redundant
configurations to support high-availability (HA) telecom
applications.
With a wide-range input of 36-72Vdc, safety agency
approvals to UL1950 and EN60950, EMI compliance
to ETSI and Telcordia standards, the cPCI420 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.
The proven design and complement of global safety
agency approvals provide for an advanced power
solution for your telecom CompactPCI requirements.

Notes:
1. Combined currents from outputs V1 & V2 not to exceed 50A total.
2. Total regulation includes line, load, and cross regulation.
3. Response to an OVP fault is a latching shutdown,
restart of the unit requires cycling of the input power.
4. May not be in regulation.
