Single phase electronic energy meter/electricity meter
DDSJ666 single phase neutral missing tamper proof meter is which can be used in one phase two wire power network. It can measure the Unidirectional or Bi-directional active energy and Maximum demand. It has fully tamper proof, key button display, power off display, event alarm functions. It complies with IEC and UL standard and has stable performance, high accuracy and convenient operation. It provides a single phase neutral missing tamper proof solution.
◆ Unidirectional or Bi-directional energy measurement, including active forward and reverse energy measurement, Instantaneous value measurement (voltage\current\power).
◆ Measure the Maximum demand with interval or slip mode.
◆ Tamper proof: Reverse current\By pass\Neutral missing\Main cover opening, when tampering happened, it can work normally and trigger event alarms.
◆ Real time clock with leap year automatically switches.
◆ Power off display with internal battery.
◆ Using automatic software calibration technology, fast speed, high accuracy.
◆ Integrated the PCB and terminal box, it is easy for SKD.
