DTSY122 Electronic three-phase four wire prepaid energy meterDetailed product description：

The DTSY122 electronic three-phase four wire prepaid energy meter is a new type of energy meter developed using the latest microcontroller technology. It completes the pre paid electricity management and load control functions of buying electricity first and then using electricity. It can effectively solve the problem of overdue electricity bills, curb overcapacity and electricity theft, realize the commercialization of electricity, and effectively control and regulate the load of the power grid. It is an ideal product. The international standard universal IC card is used for data transmission, and its functional indicators comply with all technical requirements in IEC1036, GB/T17215, and GB/T18460 standards.

The main functional features of DTSY122 electronic three-phase four wire prepaid energy meter are:
1. User pre order electricity, pre-set maximum load limit, alarm electricity setting, IC card password setting, IC card data transmission.  
2. Store factory table number, table constant, user address, name and other information.  
3. Read back information such as remaining power, accumulated negative power in the meter, and total number of power purchases.  
4. Remaining power alarm, overload alarm, and power-off control when the power is zero.  
5. High precision, high overload, high reliability, low power consumption, anti electricity theft.  
6. The meter displays the total power consumption, and the digital display shows various power consumption conditions.
