DDSY1532 SINGLE PHASE ELECTRONIC PRE-PAID TIME-SHARING WATT-HOUR METER
MAIN FEATURES
l Each meter responds to a card, well protection from forgery; date-copying function make the electricity department easier to manage.
l Once the remaining electric power is approaching the alarming power quantity, the digital tube should be lighted to remind user of timely purchasing;
l Once the electric consumption available is out, it should be auto cut-off; Auto cut-off for overload and convenient for electric department actualize add the capability; the relay has feature of high power and low consumption.
l The IC card power selling control system has the function as power selling and using control.
l Each of four periods has different rates(point period, peak period,smooth period and trough period). Every period of time can be programmed into10 periods of time and the minimum time interval is one minute;
l The watt-hour meter displays the electric quantity via digital-tube, there are six digits in total, five digits are integration and two are decimal in the interior of the meter, so, it will be displayed 8 digits when copying to the hand computer and 485.
l All the data were protected from the password and the hardware; read the data directly via LED.
l The meter has reliable clock, the life of the clock is as long as the battery when the low backup current(less than 0.5 μA)
