Low Power Comsumption, Long Life, High Accuracy

DDS238-4 W type multi-function protective smart energy meter is designed to measure single phase two 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 single 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℃~+70℃,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)".

Basic Function

• Measuring positive & negative active energy with negative energy accumulated into positive energy.
• The meter display total active energy, positive active energy , negative active energy , total reactive energy , balance active energy
• The meter also display real voltage , real current , real active power , real power factor , real frequency
• Pulse LED indicates working of meter,Pulse output with optical coupling isolation                     .
• RS485 communication port and WIFI communication
• Measuring active energy without calibration under long term operation
• Display step by step with button
• APP can display total active energy, balance active energy, real voltage , current ,active powerand remoter control on/off.
• Hour/Day/Month/Year history active energy consumption tracking by APP
• It has overvoltage and undervoltage protection , it can set value from APP and by button
• Each protection function can be opened/closed as customer requirement
• It has overload protection ,it can set value from APP
• Voice control on/off function
• Alarm event records on APP
• Prepayment function, if balance energy used up. It will cut off automatic. This function can be opened/closed by APP
• Energy data can store on memory chip when power off, it also still measure energy whenlose WIFI connection and it will update the energy on APP when connect WIFI again
• It can control on/off by hand with button when prepayment function close
• It has timing control function , it can set value from APP
• It can reset the active energy to zero from APP
