This meter has RS485& WIFI communication function, Especially the WiFi function offer the max. convinience for remote monitor and controlling by phone APP, its data communication rules comply with the requirement of MODBUS-RTU & WIFI 802.11b/g/n.

EEDTS238-7W WiFi DIN Rail Three Phase Smart Energy Meter

General Description

     EEDTS238-7 WIFI type multi-function smart energy meter is designed to measure three phase four wire AC active energy and variable parameter. The meter have RS485 communication port and WIFI communication, it can use APP for remote reading and control on/off. All of its functions comply with the relative technical requirement for class 1 three phase watt hour meter in IEC62053-21 and its data communication rules obey the requirement of MODBUS-RTU and WIFI 802.11b/g/n. It is a long life meter with the advantage of high stability , high over load capability , low power loss and small volume .

    The meters should be installed in suitable environment with ambient temperature range between-25°+55°,the relative humidity less than 75% and temperature limits between   and-40°+70°.

     The meters comply with international standard IEC62052-11 on Electricity metering equipment (AC) General requirements tests and test conditions and IEC62053-21 on Static meters for active energy (classes 1 and 2).
