DDS238-4 W single phase din rail type WIFI watt hour meter
USER’S MANUAL
1. General Description
The meter is designed to measure single phase two wire AC active energy and variable parameter. All of its functions comply with the relative technical requirement for class 1 single phase watt hour meter in IEC62053-21 and its data communication rules obey the requirement of DL/T645 or MODBUS-RTU. The WIFI communication rule obey the requirement of 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
2.Specification and Technical Parameters
1. LCD display
2. Bi-directional total active energy ,reverse active energy measure in the total active energy
3. The meter also display real voltage , real current , real power , real power factor , real frequency , real time and date
4. overvoltage and under voltage protection
5. over load protection.
6. timing and delay time control
7. Pulse LED indicates working of meter,Pulse output with optical coupling isolation
8. WIFI and RS485 communication port ,can remote control
9. All data can read from mobile phone from WIFI to cloud server
