? First, sum up the single-phase prepaid fee electric energy meter of the DDSY870 -type electronic formula, adopt the most advanced specialized integrated circuit design, full automaticity is surface mounted (SMT) The production technology is made. Circuit design and components and parts of the electric energy meter choose to be based on greater environmental permissible deviation, can guarantee the long-term stable operation of the complete machine, high-accuracy, high over load, low power consumption, the unfailing performance is high. It accords with the international canonial and advanced intellectual IC card technology prepaid fee way to adopt, built-in magnetic latching relay. Realize what control is supported is open and broken through the control relay, realize that supervises users to use the electric function after buying the electricity first. Products accord with GB/T17215-2002 " whether 1 and the intersection of 2 and resting type exchange meritorious electric energy meter " and 18460.3-2001<>. ( 18322695188) ? ? Second, working principle a electric energy meter is made the sampling signal of the voltage by the voltage divider, the shunt makes the electric current sampling signal, receive the electric current product signal of the voltage by the multiplier, produce count pulse of frequency proportional to voltage electric current product by frequency change another, through the frequency demultiplication, drive the stepping motor to measure electrical degree. 2,The electric energy of data processing is measured pulse to send CPU to deal with by the photoelectric coupler, store in the memorizer after operation. By the computer management information system, through the reader writer of IC card, certain electric quantity of load and controlling the microprocessor system in the IC card import list required, after CPU operation, offer revealing, warning status signal.

Please keep the draw out card properly.
