Functions
●
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.
●
Provides module running information for the MDU.
●
Controls the running of a single UPS and a parallel system, and reports the
UPS status information to other monitoring modules.
