Smart Wifi Meter DTS238-7 W three phase din rail current voltage display RS485 communication smart energy meter wifi
smart energy meter wifi
DTS238-7 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 meter 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 meter is manufactured complying 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)”.

2.2 basic parameters
Delayed power on/off time | 60+5s |
overvoltage / undervoltage / overload event judgment time | 3s |
Overvoltage protection value | 270V+1(default),APP can set value |
Overvoltage recovery value | 260V+1(default)= (APP overvoltage value - 10V) |
Undervoltage protection value | 170V+1(default),APP can set value |
Undervoltage recovery value | 170V+1, (default)= (APP overvoltage value + 10V) |
Overload protection value | 65A(default), APP can set value |
Delay on/off control | 00:01—24:00 Hour |
Note: when it happens interrupt power-supply , the meter will not cut off , undervoltage event must last 3s , then it will cut off.
