Main functions and characteristics
- Measurement of positive/negative active/reactive energy and demand, power consumption and demand in each tariff;
- Measurement of four quadrant reactive energy;
- 4 tariff, 10 day time period, 5 day time tables, 4 time zones and 12 public holidays can be programmable;
- Display meter data by LCD, optional backlight display;
- Scroll-display, the parameters(not exceed 32 items), time and sequence of scroll-display can be set randomly;
- Real time measurement of voltage, current, power, power factor and current frequency in each phase;
- Record the events of voltage loss, current loss, voltage qualified rate, power cut and on, programming, demand reset, broadcast time checking etc;
- With energy pulse and clock testing output interface;
- Infrared remote during power break and awakening by pressing button, infrared remote meter-reading when power break can also be realized;
- Infrared and RS 485 communication interface;
- Fault alarming;
- Record the result of current inspection without voltage;
