High Accuracy Single Phase Electric Meter 5(60)A Watt Hour Meter BS Mounting Anti Tamper

Product overview:

DDS single phase electronic watt-hour meter uses imported specific large-scale integrated circuits and other advanced technology. It can measure AC single phase active electric power which the rated voltage is 220V and frequency is 50Hz. It can measure forward and reverse active power accurately and it calculates accumulatively in the same direction. It can prevent electric larceny at the same time. It outputs heartbeat through optical couple. LED displays electricity consumption,so that it si easy to control.

Features of function:

It conduct Signal sampling from shunt voltage divider. It can drive a stepper motor to let the register calculate the energy degrees cumulatively through the processing of amplification, multiplication, integration, V/F conversion, frequency division, power driver, etc.

Intelligent Design, imported single-chip which controlled by micro computer, full digital metering, with advantages of high accuracy, good linearity, wide range, low consumption and prevent from electrc stolen. 

Reliable design, perfect power source and electromagnetism compatible design, which are suitable to the strong electromagnetism disturbance and big occasion of power source fluctuation.

Cover for meter, fully sealed dustproof and waterproof design, material of cover has excellent flame retardant and anti-corrosion, anti-aging properties.

On/Off manner, with build in relay for ON/OFF control.
