The main technical parameter

  • DTSSY877/DDSY877 electronic three-phase or single-phase prepaid watt-hour meter is a new generation pre-paid activewatt-hour meter developed by our company. It uses the newest special three-phase or single-phase electric energy metering chip to measure the electric energy: the special CPU carries on the data processing, the display and the control of the relay movement, adopts the unique bayonet safety and the protection measure: the dynamic, safe and reliable IC card encryption mechanism.
  • Advanced hardware and software fault-tolerant processing: reliable power network monitoring and anti-jamming circuit design,high-precision current transformer is selected in it, a dedicated three-phase or single-phase power supply circuitis is used.
  • It has the characteristics of reliable operation, high precision, large overload capacity, low power consumption, small volume, light weight, long life, high performance-price ratio, easy installation and so on.

It can accurately achieve the frequency of 50Hz three-phase AC active power measurement and the realization of pre-payment. All the performance and technical indexes of this product are in line with the related indexes of GB/T18460 and GB/T17215 (IEC61036).

The Structure Features


Topresale electricity and run out of power automatically. It will remind for electricity purchasing, it will send out an alarm when the remaining quantity of electricity is less than a certain number. The value and mode of alarm can be set flexibly according to the actual demands. LCD displays all kinds of data, and the power data rewriting function is convenient for the power supply department to manage. One table, one card, multiple dynamic encryptions to assure the safety of users.

The partition and classification of electric meters can ensure the security (multiple ciphers) of different kinds of electric meters, which can effectively prevent the attack of the bayonet, and the power supply mode of switching power supply, any phase of which can maintain the normal operation of the meter.

The unique anti-crash circuit and several fault-tolerant designs to ensure the safe operation of the meter, the unique power supply detection features ensure the normal storage of the power-down data and ensure the absolute accuracy of the measurement data (without losing the pulse when the power is down).

Meters

The utility model has the function of overload control and the metering of zero-crossing electricity, and also can achieve the remote meter reading and control, the special three-phase electric energy metering chip ensures the measurement of electric energy much more accurate, and supports the work of air switch and AC contactor.

mounting size
  • 1 The watt-hour meter should be kept dry and clean. It should be wiped gently on the surface of the dry cloth regularly.

2 The jack of the electric energy meter can not be blocked or plugged with other foreign matters.
