The branch current monitoring system provides a cost-effective solution for electrical load management making it ideally suited for applications where load capacity requirements are dynamic, such as power distribution units (PDUs) for the data center industry or, in any location where monitoring individual electrical loads is critical.
The branch current monitor reports the current level of each of the circuit breakers of a panelboard to provide timely circuit loading information. In addition, as the circuit load approaches one of two user set levels, an alarm can be generated back to monitoring software such as PowerLogic System Manager Software.
Two models of the branch current monitor are available. The BCM42 consists of rail mounted solid-core CTs intended for mounting inside new panelboards or complete panel retrofits. The BCMSC model is made up of split-core CTs that are an ideal solution for retrofit applications in existing panelboards. The BCMSC can be ordered in a variety of CT quantities to more closely meet your current monitoring needs.
 |
Up to 32 BCMs can be daisy chained on one Modbus® RS485 string for easy networking capability. |
|
One BCM42 provides current levels on each circuit of a 42 circuit NQOD panelboard. |
|
Split-core CTs are perfect for quick installation on critical load applications that can't be powered down. |
|
Provides Modbus registers for current limit alarms to help prevent overload circuit breaker trips. |
|
Integrates to an optional network display for local indication. |
The MCM8364 is designed for OEM style placement in electrical distribution equipment. The MCM8364 is configurable to meter 1 or 3 phases of up to eight individual loads, six loads if neutral monitoring is required. The MCM will monitor up to 10,000 A per service using standard 5 A CTs. All of the metered circuits must share a common voltage source. The MCM8364 is a great solution for monitoring critical power distribution equipment and provides 24 different electrical metering quantities plus an additional nine Modbus register alarms.
With one RS-485 connection, the multi-circuit meter provides Modbus RTU communications output that communicates to each individual metered circuit. Up to 30 multi-circuit meters can be addressed on the same Modbus network. The multi-circuit meter can provide warnings to the central monitoring computer via its Modbus output using the MNode software provided or can be integrated into PowerLogic SMS software. The MCM also works with the submeter display as shown below.

The PowerLogic submeter display (SMD) is a comprehensive electrical submetering display that provides a view of electrical parameters from multiple metering products with one networked LCD. In addition to viewing system data on the display itself, you can also view data on a remote PC via a network connection. Touch pad buttons provide a convenient way to view downstream devices on the power-monitoring network. The display is RS-485 Modbus RTU compatible. It has additional RS-485 and RS-232 Modbus ports for networking to additional displays or to a master PC. The submeter display is compatible with the following metering devices: BCM, MCM, & Enercept® meters.
