Three-Phase Metering

NEM-6L24

NEM-6L24 is a three-phase energy submetering module for DIN-rail mounting with external current transformers up to 100 A. It measures voltage, current, active, reactive and apparent power, power factor, frequency and energy per phase with accuracy class 1 % and delivers the data over Modbus-RTU via RS-485 or UART TTL with galvanic isolation. Any Modbus master can poll it: a PLC, a BMS or SCADA controller, a PC or a gateway. The module is used for energy submetering of HVAC and ventilation units, measurement and verification of energy savings, BMS and SCADA integration and retrofits of existing switchboards.
