DSTY3333 digital energy meter is used for measuring three phase active energy. It is of high accuracy and reliability.
Product Brief IntroductionThe type DTSY3333/DSSY3333 electricity watt-hour meter is the new type of IC card prepaid meter,which has many functions such as electrical energy measuring,load control and management of user information etc. It is an ideal product for us to realize electrical energy commercialization and solve charge question and adjust load conditions in the electric network.There are two ways of connection:direct connection or through current transformer connection.Each performance index of it conforms to GB/T17215.321-2008 1.0&2.0 class static A.C active watt-hour meter and GB/T18460.3-2001. 2.Functions and Features Measure three phase active energy, and it needs not to calibrate for long term working. Three-phase power supply, any one wire(three phase three wire) or any two wire (three phase four wire) power cut, the measurement accuracy is not affected. Phase failure indication function or voltage indication function. There are signal output port. One meter with one IC card,and it has good anti-fake . The LED will flash when the residual electricity equals to the alarming electrical quantity,Reminding of users to purchase electricity in time. It will trip when the residual electricity equals to zero. Automatically power cut for overload),it is easy for power department to set capacity. Check and modify for data ,easy management for power department. Adopt the meter external installation for load switch ,adopting relay control in the meter.( contact capacity for 250VAC/5A) The supporting IC card management system has the perfect sale power management and use power monitoring functions etc. May expand RS485. May select anti-tampering function. Main Technical Data
