US standard single phase three wire wifi energy meter 110VAC/100A

The meter is manufactured complying with international standard IEC62052-11 on "Electricity metering equipment (AC) General requirements test and test conditions” and IEC62053-21 on “Static meters for active energy (classes 1 and 2).

Specification

Basic Features

1 Measuring positive & negative active energy with negative energy accumulated into positive energy,.

2 The meter also display  real voltage , real current , real active power;

3 Pulse LED indicates working of meter,Pulse output with optical coupling isolation;

4 Measuring active energy without calibration under long term operation;

5 Display step by step with button;

6 It can use APP software for data reading and remote control on/off;

7 Meter should used with AC contactor to control on/off;

8 it has timing control function , it can set value from APP.

Working principles

Single phase voltage and current are sampled from respective sampling circuit and transformed into suitable signal, which is carried into integrated circuit , then the meter output pulse signal in positive appropriation to measured power to drive LCD counter to realize energy measurement. The meter has energy pulse output for testing with pulse width of 80+20ms.

Structure

The meter consists of meter base , meter cover , terminal base , terminal cover . there are lead seal on meter cover  and terminal cover . A special screw is used to fix the terminal cover on which a lead seal can be installed.

Dimension

Wire connection

L-N connect on AC Power, Relay connect on AC contactor.
