Description: If you want to control the meter on off, you have to connect to relays. The meter output the voltage signal. Please noted, this TUYA wifi energy meter will update the Kwh data when disconnect with wifi, other type Metering circuit breaker will not increase the Kwhwhen discounnect with wifi. 1. Remote Control ON/OFF by Tuya APP or Smart Life APP at anytime from anywhere 2. Total active energy kWh measure 3. APP can read kWh , R.M.S current , voltage , active power 4. Timer control function 5. Delay time cut off function 6. LCD display, Real-time display of Voltage, Current, Active Power, reactive Power, power factory ,frequence, total Energy kWh 7.

Pulse Frequency: 2000imp/kWh 11. 35mm Din Rail install 12. can use same TUYA APP, compatible with other TUYA product such WIFI socket , led ,fans and so on 13. Active energy accurate iscla 1 , IEC62053-21 Push the button last more than 10s , the WIFI led will flash quickly , then use APP to operation bear 400V /hour not damage Note:This meter Only supports 2.4G Wirele Network, NOT for 5G 1. General Description DDS238-1 WIFI type multi-function smart energy meter is designed to measure single phase two wire AC active energy and variable parameter. The meter have WIFI communication , it can use APP for remote reading and control on/off. Its data communication rules obey the requirement of WIFI 802.11b/g/n. It is a long life meter with the advantage of high stability , high over load capability , low power lo 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 (claes 1 and 2). 2.Specification and Technical Parameters 2.1Specification Meter type DDS238-1 WIFI Rate frequency 50 or 60 Hz Rated current 5(60)A Clamp CT or 10(100)A Clamp CT Rate voltage 120V / 220V / 230V /240V Limits voltage range 100 270V kWh Accuracy Cla 1 R.M.S accuracy Cla 0.5 LCD display kWh 999999.9 kWh Starting current 20mA(min measure ) Voltage circuit
