MID energy meter, three-phase, current transformer connection 1(6) A

The B24 is Janitza's three-phase MID-certified energy meter for connection through current transformers, for feeders whose current is too high to meter directly. The transformer ratio is set on the meter itself, so the readings are shown and sent in primary values. Like the B23 it records active, reactive and apparent energy in four quadrants across two tariffs, shows instantaneous measured values, and is available with pulse outputs only or with an RS-485 (Modbus RTU) or M-Bus interface.

Applications

Energy Monitoring SystemsEnergy monitoring systems measure and analyse electricity consumption continuously, at facility, feeder, department or machine level. Alongside electricity, other energy sources such as water, natural gas and compressed air can be tracked through the same system. Data from Janitza energy analyzers is collected centrally in the GridVis software, where consumption trends, load profiles and energy performance indicators can be followed. Automatic reporting and alarm functions make abnormal consumption and energy losses quick to identify. Energy monitoring systems help to allocate energy costs correctly, to identify inefficient points of consumption and to improve energy performance continuously. They also support ISO 50001 energy management processes and make it possible to track energy performance indicators such as PUE in data centers.
