Usage
DDSY54 single phase prepayment electronic energy meter completely conform to GB/T184603-2001 and GB/T17215-2002. It is used for measure AC single phase active energy with rated frequency 50Hz, it can realize prepay charge and use electricity later manage function through standard IC card.
Characteristic
The meter is adopting SMT craft, specialized CUP, specialized single phase energy measure IC etc many kinds of advanced technology and craft, the meter is high precision, high reliability, low consumption, excellent electromagnetic compatibility and perfect anti electricity-stealing function.
Main functions
Through our company offered management system, it can realize to set and surveillance of all kinds of information of user pre purchase energy, preset maximum load, warn energy, electricity price set and adjust, authorization of operator, purchase energy record, accumulative energy used, remnant energy, electricity-stealing time etc. It is convenient for power supply department to reduce read operator, prevent and strike electricity-stealing behave, improve management level. The meter is specialized for operation on inside room, the adaptable temperature is -10- +55℃, relative humidity is not more than 85%.
