Description:
The Compere KPM312 meters up to four three-phase circuits (or twelve single-phase circuits) from one compact DIN-rail unit, making it the most cost-effective way to sub-meter a distribution board with many outgoing ways - tenants in a mall, floors in an office block or feeders in a plant room. Each channel records voltage, current, power, four-quadrant energy, demand, run time and harmonics to the 31st order to Class 0.5S. Circuits are measured with the dedicated KPM312 split-core CT sets (5 A to 800 A, mixable across channels) and data is read over RS485 Modbus RTU, with Wi-Fi, 4G or LoRa available as options. Order the meter plus one CT set per circuit.
