The DDSU666 Single-phase electronic type guide rail mounting electric energy meters.

Short Description:

It is used to monitor and display the grid power (voltage, current frequency and energy), and transfer this info to solar inverter via RS485 communication in zero-export system.   The DTSU666 series three phase four wire electronic energy meter (din-rail) is designed based on power monitoring and energy metering demands for PV power plants etc. Mainly applied into the measurement and display for the grid parameters in the zero-export system, including grid voltage, current, active power, reactive power, frequency, etc.
