1. General Description
DDS238-4 W type multi-function 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℃ ～ +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)".
