1. DDSY1675 single-phase electronic prepaid electric energy meter is a new type of C card prepaid electric energy meter developed by our company on the basis of single-phase electronic energy meter with excellent performance, which has multiple functions such as energy metering and load control. This meter is an ideal product for reforming the current electricity consumption system, realizing the commercialization of electric energy, and solving the difficulty of charging. The meter uses special large-scale integrated circuit, with fewer peripheral components, simple structure, high reliability, and low power consumption , long service life, etc. It can be used to measure single AC active electric energy with rated frequency of 50Hz. All performance indicators of the product comply with all technical requirements for single-phase sub type prepaid electric energy meters in GB/T17215.321-2008 Class 1 and Class 2 Static AC Active Energy Meters and GB/T18460.3-2001 IC Card Prepaid Electricity Selling System.

2. DTSY1675 three-phase four wire electronic prepaid watt hour meter is a new type IC card prepaid watt hour meter with multiple functions such as energy metering, load control and user information management. It is an ideal product for reforming the power consumption system, realizing the commercialization of electric energy, solving the difficulty of charging and regulating the load state of the power grid. There are two access modes for this series of three-phase four wire electronic prepaid electric energy meters: direct access type or through transformer access type. All performance indexes of the product meet all technical requirements for three-phase sub type prepaid watt hour meters in GB/T17215.321-2008 Class 1 and Class 2 Static AC Active Energy Meters and GB/T18460.3-2001 IC Card Prepaid Power Selling System.

1. DDSY1675 single-phase electronic prepaid electric energy meter
