Three phase multi-tariff energy meter

الوصف

Three phase multi tariff energy meter type DTSF**9 is used to measure *0HZ AC active energy and the power flow of peak time, flat time and off-peak time. All of its functions comply with the relative technical requirements for class 1 single-phase watt-hour meter in IEC*********0. The manual programming s is used for setting tariff periods and adjusting time when RS**5 communication device or infrared communication equipment is unavailable. MAIN FUNCTION 1. Four tariff: total, T1, T2, T3, T4. 2. Present month max. demand, last month max. demand and last 2 month max. demand and record of occurred date. 3. Max. demand cycle is *5 minutes. 4. Slipping time is 1 minute. 5. Phase absence display and phase absence record. (the Chinese words is too long) 6. *0 periods. 7. Period interval is min. 1 minute. 8. Display turns: total, T1, T2, T3, T4, Demand 1, Demand 2, Demand 3, time and date. 9. Infrared communication: reading power consumption, setting period, setting meter No. and adjusting time. *0. RS**5 communication: reading power consumption, reading max. demand and occurred time, phase absence times and period, last phase absence starting and stopping time, setting meter No. and adjusting time. *1. Manual programming : setting period and adjusting time. SPECIFICATION 1. Frequency: *0Hz 2. Starting: 0.4%Ib (direction connection); 0.2%Ib (CT connection). 3. Creeping: there is no complete pulse output, with *****5% of rated voltage in voltage circuit without current in current circuit. 4. Multi-tariff part a. Daily time error: <0.5second. b. Clock power when main power off: 8&#**6;A. c. Battery life: *0 years. d. Period exchange error: <1ms. e. Infrared communication distance: 5m. f. RS**5 communication distance: ***0m. g. RS**5 terminal: ***2pcs. 5. Power consumption: <2W, 8VA. 6. Working temperature: **0~*5&#***1;, working humidity: <*0%. 7: Dimension: **8×**5×*2; weight: 2kgs.
