Product Name: Single-Phase Static Watt-Hour MeterModel Number: DDS200DPlace of Origin: ChinaGeneral introduction:DDS200D serial single-phase static watt-hour meter has 2 communication modes of infrared and RS485. The two modes are optional. It can control current switch in meter through infrared mode with infrared HHU, which will realize load interrupt and load restore function. Adopting the latest special energy measuring chips developed by ADI Company and using ЎЖ-¦¤ sampling conversion technology, the meters achieve high accurate, high overloading single-phase active electric energy measurement. DDS200D serial meters can be used for collect meter reading system, It is very facility for electric power department to improve meter reading efficiency and control power turn-on and power turn-off to user in arrear.Functions:1) Energy measurement: to measure and display accumulative electric consumption2) Memory function: when power supply is cut off the information in the meter will notbe lost3) Display function:a) 6 digital LED displays accumulative electric consumption (kWh)b) 6 digital register displays accumulative electric consumptionc) Pulse indicator light winks when power has been usingd) Reverse pulse indicator light lightens when reverse usee) Communication indicator light winks when communicatingf) The LED display mode can be set as constant display or in-turn display throughHHU ( display 20 seconds stop 5 minutes)4) Communication function: with RS485 and infrared communication port, which canrealize data exchange with meter reading unit or auto meter reading system5) Pulse output function6) With infrared meter reading unit to control load interrupt and load restore (cut off,recover current) of meter7) DDS200D serial single-phase static watt-hour meter can be used with DataCollection Unit produced by SEASUN to realize meter reading in small fieldSpecifications and parameters:1) Model: DDS200DA (LED display)a) Class: 1.0, 2.0b) Rated voltage: 220Vc) Rated current: 5(20)A, 10(40)A, 15(60)A, 20(80)A2) Model: DDS200DB (register display)a) Class: 1.0, 2.0b) Rated voltage: 220Vc) Rated current: 5(20)A, 10(40)A, 15(60)A, 20(80)A3) Model: DDS200DC (LED and register)a) Class: 1.0, 2.0b) Rated voltage: 220Vc) Rated current: 5(20)A, 10(40)A, 15(60)A, 20(80)A4) Operation voltage: 70% Un - 120% Un5) Referenced frequency: 50Hz6) Power consumption:7) Operation ambient temperature: -250 ~ +550oC8) Limited temperature: -400 ~ +550oC9) Temperature range for storage: -250 ~ +700oC10) Relative humidity: ≤85% (temperature is 250oC)11) Outline dimensions: 174 x 126 x 90mm
