General

WIFI VAP type multi-function protective smart energy 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)".
