Product Name: 3-Phase Static Prepayment Watt-Hour MeterModel Number: DTSY200-BPlace of Origin: ChinaGeneral introduction:DTSY200-B three-phase static prepayment watt-hour meter is used to measure three-phase active electric energy in the 50Hz AC circuit. Adopting high-accuracy three-phase sampling special purpose chips, the product can carry through sampling measurement and transmit it to intellective microprocessor. After conversion and processing, the electric quantity display and interface control are completed. Data transfer is completed by IC card. Electric quantity and power consumption data are mutually transferred between the meter and electricity selling managemen t system to realize the functions of electric energy measurement and electricity charge prepayment. So, the meter is a necessity for power departments to reform electricity charge method and to achieve the management of prepayment power use.Main technical index:1) Current specifications: 3 x 5(20)A, 3 x 10(40)A, 3 x 15(60)A, 3 x 20(80)A2) Accuracy class: 1.0 class3) Reference voltage: 3 x 220/380V4) Reference frequency: 50Hz5) Operation voltage range: 0.9 Un ~ 1.1 Un6) Temperature range in operating environment: -25 ~ +55oC7) Contact capacity of electrical relay while power is turn off: AC 3A / 220VMain functions:1) Energy measuring function2) Monitor and control function3) Memory function4) Display function5) Identification function6) Adding function7) Back writing function8) Pulse output function
