DTSY156 the IC card pays in advance spends three-phase four the electrical energy table is uses the large-scale special-purpose monolithic integrated circuit electric appliance and the high reliable electronic component design, the periphery part few, structure simple,the reliability is high, power loss low status
characteristic.

     The product soft, the hardware design thought is unique, does not have dying machine, the loss data phenomenon, the system has the high antijamming, the high overload, redundant
reliable, the long life performance. This table uses the IC card, the read-write speed quick,
is convenient may arrange, the service life may duplicate 100,000 above time, under the electrical network big undulation condition,
still might the normal work (under 65%--135% Rated voltage be possible normal work, in to lack in at least) the situation, paid in advance
spends the function normally to move the line.
