and the system control card. The ECM ensures equalized output currents
between modules so that load power is equally shared.
The ECM provides module working status information to the monitoring
system.
The ECM controls the running of a single UPS and a parallel system, and
reports the UPS status information to other monitoring modules.
The system provides three types of CAN communication: monitoring CAN
communication, intra-rack parallel CAN communication, and inter-rack
parallel CAN communication.
The control module consists of one active ECM and one standby ECM.
Hot-swappable, 1 U high.
Description
The PARALLEL port transmits parallel signals between racks.
The BSC port is used in a dual-bus system to synchronize
output frequencies and phases between UPS systems,
ensuring that two buses can switch with each other.
BSC cables are hot-swappable.
NO TE
No parallel cable is required for a single UPS.
