Single Phase Static kWh Meter

الوصف

CONFORMED STANDARD IEC*******1/*1 IEC*******1/*2/*3 IEC*******1 FUNCTIONS: Measure reverse and forward energy, and reverse energy is measured as forward energy. LCD display, it can display for a long time at power failure. Real time clock. RS**5 communication port. FEATURES: Active energy measurement, no need to calibrate for a long working time. LSI design, less spare part, less power consumption, simple structure. Active energy meter keep a good linear error within the range 1%Ib~Imax. Use quality component with long service life, the accuracy cannot be affected by the frequency, temperature, voltage, harmonic. It is reliable and with long service life. RS**5 communication port realizing remote meter concentrative reading. PARAMETERS: Model DDS**0 CLASS 1.0S Display LCD Rated Voltage **0V***0V Rated(Max.)
