Multi-load power analyzer for single or three-phase systems installable on panels or DIN rails. Manages current input via two groups of split-core current sensors connected with RJ-11 connectors. The EM271 is equipped with a LCD display with controls to display measurements and configure the system, a RS485 port and two pulse outputs or two RS485 ports for daisy chain connections. Thanks to the SUM function, it also displays total load consumption values.
