As a control interface for the entire system, the ECM communicates with each module
and provides a bus for communication between the dry contact card 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.
