DSSY722 type three-phase electronic pre-paid time-sharing watt-hour meter
1.Brief introduction of product
DSSY722 type three-phase electronic pre-paid time-sharing watt-hour meter is a new type of IC card pre-paid time-sharing meter , which has such function as power time-sharing meter, load control and customer information management. It is an ideal product when reforming electric-use system, achieving electrical energy to commercialize, setting charge and adjusting load stage in the electric network. All the indexes comply with the technological specifications aiming to the three-phase electronic pre-paid time-sharing watt-hour meter in the standard of GB/T 18406.3-2001 and GB/T 17215.321-2008.
2.Function and features
-Measure three-phase active electric energy , do not need calibrate for long-term operation
-Three-phase power supply can assure accurate metering in case of cut off in one line(each line of the three-phase& three-wire)or two wires (any two wires of the three-phase or four wire)
-Indicative function for phase lose or voltage indication
-Each meter responds to a card, well protection from forgery
-Once the remaining electric power quantity is approaching the alarming power quantity, the digital tube should be lighted to remind user of timely purchasing
-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 features of high power and low consumption
-Date-copying function make the electricity department easier to manage
-The IC card power selling control system has the function as power selling and using control
-Each of four periods has different rates (point period, peak period, smooth period and trough period). Every period of time can be programmed into 10 periods of time and the minimum time interval is one minute.
-The watt-hour meter displays the electric quantity via digital- tube, there are six digits in total, five digits are integration, and one digit is decimal. There are six digits are integration and two digits are decimal in the interior of the meter, so it will be displayed 8 digits when copying to the hand computer and RS485
-All the data were protected from the password and the hardware
-Read the data directly via LED
-The meter has a reliable clock, the life of the clock is as long as the battery when the low backup current (less than 0.5 μA)
