Standard energy meter

SYS120 single-phase multi-function standard table

SYS120 single-phase standard energy meter is the latest digital electronic technology, using 16-bit high-speed high-precision A / D conversion chip, DSP high-speed processors and CPLD as the core of intelligent multi-function high-precision power measurement instruments.

Its main features are:

1> measuring range, the current is 0.001A-100A.

2> can measure single-phase active energy, single-phase sinusoidal reactive power function.

3> configuration LCD display interface, can be a screen display voltage, current, phase, frequency, active power and reactive power and other electrical parameters.

4> configuration RS232 communication port, can be directly connected with the PC computer to provide measurement data to the PC, to provide communication protocol, can be controlled by the PC, the implementation of automatic measurement.
