General introduction:DTSD200/DSSD200 serial three-phase Static multi-functional watt-hour meter is the new Static three-phase active and reactive multi-functional energy measurement product designed and developed by Tianjin Seasun Electronic Industrial Co., Ltd. It is designed and manufactured according to the practical power using situation of the industrial users, adopting large-scale integrate circuit, digital sampling processing technology and SMT technology. The watt-hour meter can measure the active and reactive electricity quantity and the required quantity of all directions, and own the functions of 485 communication, manual and infrared power break awakening, charge record. And it possesses stable performance, high accuracy and convenient operation.Main technological index:1) Accuracy grade: active 0.5s/0.5/1 reactive 22) Rated current: 3 x 0.5(2)A, 3 x 1(2)A, 3 x 1.5(6)A, 3 x 3(6)A, 3 x 5(20)A, 3 x 10(40)A,3 x 15(60)A, 3 x 20(80)A, 3 x 30(100)A3) Reference voltage: 3 x 220/380V, 3 x 57.7/100V (3-phase, 4-line), 3 x 100V(3-phase, 3-line)4) Rated frequency: 50Hz5) Starting current: active 0.001 In (grade 0.5s, grade 0.5), 0.002 In (grade 1),reactive 0.003 In (grade 2)6) Shunt running: shunt running defending logic design7) Normal operation voltage: 0.9 Un - 1.1 Un8) Limited operation voltage: 0.75 Un - 1.15 Un9) Power consumption of voltage circuit: ≤2W and 5VA10) Power consumption of current circuit: ≤2.5VA11) Digital reserved battery voltage: 3.6V DC12) Power break meter reading battery voltage: 6.0V DC13) Clock accuracy (day error): ≤0.5s (23oC)14) Normal operating temperature: -20 ~ +50oC15) Limited operating temperature: -30 ~ +60oC16) Storage and transportation temperature: -40 ~ +70oC17) Storage and operating humility: ≤85%Basic functions:1) Electric energy measurement function2) Maximum quantity demand record function3) Multi-tariff function4) Decompression record function5) Current loss record function6) Voltage eligibility rate record function7) Electric energy freezing function8) Digital in-turn display function, key-press display function9) Power break, power supply resuming record function10) Programming, clearing the required quantity, adjusting time in broadcastingfunction11) Alarming function12) Programming functionAdditional functions:1) Monthly forward active electricity consumed record function2) Ending forward active electric energy freezing record3) Charge representing the daily integral point active electronic energy record4) Charge curve record function5) Independent 485 communication interface and infrared communication interface6) Power break awakening function7) 3-phase current inspection function when no voltage8) Multi-functional (clock, required quantity cycle replacement, period of time switching)9) Inspection output bayonet function
