3.1Branch Circuit Monitoring Control Board (BCB)

The BCB is the main processing and storage circuit board of the Liebert LDM. It is a DSP-based logic controller with internal flash memory and non-volatile memory. The BCB also includes a battery- backed real time clock.

One of the power parameters, kilowatt-hours (kWh), data is accumulated on this board for the panel- board mains, subfeeds and each branch circuit breaker. A Modbus command is provided to reset all accumulated power usage.
