New Productors WIFI din rail smart energy meter

1. Safety Instructions

WIFI din rail smart energy meter is designed to measure three phase four wire AC active energy and variable

parameter. The meter have wifi communication,it can use APP for remote reading and control on/off.

It’s data communication rules obey the requirment of 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 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

3. Basic Feature:

3.1 Measuring positive & negative active energy with negative energy accumulated intopositive energy. 3.2 The meter display total active energy, positive active energy,negative active energy,total reactive

energy,positive reactive energy,negative reactive energy,three phase voltage,three phase current,total active

power,three phase active power,total reactive power,three phase reactive power,total power factor,three phase

power factor,frequency. 3.3 Pulse LED indicates working of meter,Pulse output with optical coupling isolation

3.4 Set product button:you can push this button to check the different data display,if you push the setting button

last 10s,meter will enter into the status of waiting for WIFI distribution network .if you want to reset status of WIFI

distribution network,you also can push thesetting button last 10s. 3.5 APP can display total active energy, positive active energy,negative active energy,total reactive

energy,positive reactive energy,negative reactive energy,three phase voltage,three phase current,total active

power,three phase active power,total reactive power,three phase reactive power,total power factor,three phase

power factor,frequency.

3.6 APP on/off operation

3.7 Installation:The meter can be installed on a 35 mm DIN rail

3.8 The meter should be install in the water proof box indoor or outdoor.the meter's boxshould be fixed on strong

and flame-resistant wall with a recommended height of about 1.8m,where there is no corrosive gas around. 3.9 The meter should be install fully in accordance with connection diagram on the terminalcover,it is better to use

copper as the leading wire for connection.All screws should betightened. 4.0 WIFI led indication,if you push the setting button last 10s,the WIFI led will flash 1s interval after the LCD

display“ ”,its means meter enter into the status of waiting for WIFI distribution network.if WIFI led light

on all time,it means meter connect the WIFI successfully. 4.1 Impulse led indication:it will flash green color with different speed according the current load of the meter. 4.2 Relay indication:indication light off means relay switch on,indication light on means relay switch off. 4. Working principles

Single phase voltage and current are sampled from respective sampling circuit andtransformed into suitable

signal,which is carried into integrated circuit,then the meter outputpulse signal in positive appropriation to

measured power to drive LCD counter to realize energymeasurement.The meter has energy pulse output for

testing with pulse width of 80+20ms
