Basic block diagram of single converter shelf System
Operation
Power comes in as -48V and is distributed in an A and B redundant fashion to each of the converter cards and the
alarm card. There are two +/-190V circuits on each converter card. The circuits both boost the voltage and limit the
current as prescribed by UL60950-21 and GR-1089-CORE.
Warning: Ground faults or short circuits on the output do not permanently disconnect the output. The converter circuit
tests the line every 4 seconds and will re-energize if the wiring fault is cleared.
A serial communication bus links each converter to an alarm card at the end of each shelf.
The alarm card provides major and minor form C contacts, manages the converters and relays information to a Lineage
Power CPS6000 family controller using Galaxy Protocol over an RS485 bus. Up to 24 shelves can be controlled and
monitored by one CPS6000 family controller. The CPS6000 controller is WEB and SNMP capable.
Configurations
32 circuit, front access +/-190V shelves come in two configurations - airflow from bottom to top and airflow from top to
bottom. A single IP drop can be used to manage up to 24 shelves or 768 circuits.
