3 Phase 60A remote control wifi smart Din rail energy meter kwh with over under voltage current protection RS485. The historical information function not available at this moment. Please noted if you use the meter for 110V, You have to adjust the over and under voltage value, or the meter cut off the power because under voltage protection. Noted: there are lan settings, you can control locally. The meter cut off the power in 3s when over or under voltage, reconnect in 30s.
Over current protection 1-100A adjustable (default 100A). DTS238-7 WIFI type multi-function smart energy meter is designed to measure three phase four 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 three 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). Note: when it happens interrupt power-supply , the meter will not cut off , undervoltage event must last 3s , then it will cut off. Current circuit is less than 1.5VA / each phase. Voltage circuit is less than 2W/8VA each phase. Under the rated voltage , rated frequency and COS=1 , the meter shall start and continue to register on application of 0.2% In (if CT is used) or 0.4% Ib. The meter has anti-creeping logical circuit. When 115%Un is connected to the meter and current circuit is cut , the meter shall not create more than one pulse in a stipulated time. The meter can be used for at least 10 years in normal operation specified in this manual. 2.2.6LCD: 6+2 (999999.99kWh). 3.1 Measuring positive & negative active energy with negative energy accumulated into positive energy. 3.2The meter also display three phase real voltage , real current , real active power , real power factor , real frequency. 3.3 Pulse LED indicates working of meter, Pulse output with optical coupling isolation. 3.4 RS485 communication port and WIFI communication. 3.5 Measuring active energy without calibration under long term operation. 3.6 display step by step with button. 3.7 it can use APP software for data reading and remoter control on/off. 3.8 it has overvoltage and undervoltage protection , it can set value from APP.
3.9 it has overload protection , it can set value from APP. 3.10 it has timing control function , it can set value from APP.
3.11 it can reset the active energy to zero from APP. Three 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 step-motor counter or LCD counter to realize energy measurement. The meter has energy pulse output for testing with pulse width of 80+20ms. 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. The meter can be installed on a35 mmDIN rail.
6.2.2The meter should be install in the water proof box indoor or outdoor. The meter's box should be fixed on strong and flame-resistant wall with a recommended height of about1.8 m, where there is no corrosive gas around.
6.2.3The meter should be install fully in accordance with connection diagram on the terminal cover, it is better to use copper as the leading wire for connection. All screws should be tightened. 6.2.4Diagram for installation dimension.
7.1 Heavy impact should be burdened to the products while transportation and unpacking. 7.2 The products should be stored in the original package and kept in place with temperature between-40°+70°, the relative humidity less than 75% and no corrosive gas around. 7.3 Instorehouse , the meter should be placed on the shelf when kept in stock , there should not be more than 7 cartons piled up in vertical. Single-packed meters can not be piled up with more than 5 meters in vertical. 9.1 Read command(function code 03).Note 1: one register address is store 2 byte data , so the data length read as 4 byte when data number is 2. Note 2::you can use ID ID(0x00) to broadcast and got data when you do not know the meter ID. But this ways is only for 1 pcs meter to connection on RS485 wire. Please scan the two-bar-codes to download the WISEN software. When the meter power on , you can push the setting button last 5s , meter enter into the status of waiting for WIFI distribution network and the WIFI led will flash 1s interval. Its means meter enter into the status of waiting for WIFI distribution network. If WIFI led light on 5s , light off 0.1s , it means meter connect the WIFI successfully. Now the meter only used under 2.4GHz WIFI network , it can not use under 5GHz WIFI network.
Select the WIFI distribution network. Input the WIFI network account and password , then confirmed to next step. Flash1s interval : meter enter into the status of waiting for WIFI distribution network. Light on 5s , light off 0.5s : meter have connect the WIFI and login in cloud serve.
The meter will display online or offline after you add the device successfully. You will see the active energy data and remote control button and timing setting button in the menu. Control button : used for control on / off of meter output.Reset button: used for reset the total active energy to zero. Timing button: used for timing control on/off and time delay control on/off.
Time control :you can add the time which is control and which is control off , if you do not select week , it will save as single time control. If you select the week, it will save as cycle control.
Time-delay control : you can set 1minute to 24hour max to time delay control. For example , you can use delay time control to control off theBatterycar charging after 2hours. The meter do not have time clock internal , the time control is decide to cloud serve, so make sure the meter connect the available WIFI network.
Setting button : for protection value and unit price , starting active energy value setting. Then APP will write the balance kWh into the meter , when the meter balance value used up to zero. The meter will cut off load automatic. When you closed the prepayment function.
The meter will recover to normal function using. Voltage high limit(V): the overvoltage protection , it will cut off after high than this value. Voltage low limit(V): the undervoltage protection , it will cut off after lower than this value. The voltage high limit value must bigger than the Voltage low limit value.
Current high limit(A): the overload protection, it will cut off after high than this value. For overvoltage/undervoltage/overload event , these status must last 3 s , so the meter will cut off for protection. It will delay 60s to confirm the voltage and current recover to normal status after cut off. It will switch on automatically after confirmed the value recover to normal status.
Starting kWh value :this value is used for calculating the contrast active energy. If the user want to know the power company meter have run how many after fixed time, you can input the current total active energy of the power company in here! For example , the power company meter is display 50kWh, you can input the 50kWh in the starting kWh value.Meter price : how much price for each kWh. It will show the last 7 days and 30 days total active energy consumption. And total active energy cost. (only special order in some country). S value and bi-direction active energy and contrast active energy.
Import active energy : it measure the total positive active energy. Export active energy : it measure the reverse active energy , such as solar power generation , reverse wire connection , some power generator working. Contrast active energy : it is used for contrast the kWh running with the power company meter or other kWh meter. S value all measure theCurrent instantaneous value. Management : you can change the name of your meter and delete the meter from your device list.Smart interaction: you can use voice to control the meter on/off , now only support the Cat Elf smart sound and Echo smart sound device.
