summary
development of ddsy193 type single-phase electronic prepaid watt hour meter to achieve the power metering products of electronic and information technology, standardization, implementation of the first payment after meet the electricity prepayment function, improve the collection efficiency and reduce the labor cost of electricity power enterprises. the product has the advantages of accuracy, overload tolerance, low power consumption, maintainability, etc.
main features
■the positive and negative active power can be measured accurately, and the active power can be accumulated according to the positive electric energy
■after the purchase of electricity, the power consumption is lower than the set of pre alarm, run out of power consumption
■the use of ordinary contact ic card, the electric energy meter parameters set, pre stored power
