DTSDI311 ТРЁХФАЗНЫЙ четырехпроводный ЭЛЕКТРОННЫЙ MULTI-ФУ

Energy Measurement Time sharing measure active forward power, reverse active power, reactive forward power, reverse reactive power, reactive power four-quadrant power, reactive measurement can be set. Preservation of the previous 12 months electricity consumption data. Demand Measurement Time sharing measure the largest demand and the occurrence time of active forward power, reverse active power, reactive forward power, reverse reactive power, reactive power four-quadrant power . Preservation of the previous 12 months electricity demand data. Rate With Time Can set 12 time zones, 4 sets time tables, 4 rates, 12 days time, 30 holidays. Carrier communication functions The meter can upload the data to the remote electricity meter reading system through low-voltage carrier communication interface, and can achieve the control of energy meter relay through carrier. Real-Time Measurement Accurate measurement of voltage, current, active power, reactive power, power factor, frequency and other parameters. Acousto-Optic Alarm With sound and light alarm function such as broken phase, loss of voltage, loss of current, reverse phase sequence, reverse power, the battery under-voltage, hardware failure. Event Log records of recently 10 broken, lost pressure, the pressure loss, loss of flow, overload, programming, power, phone records and the last three programming records of power-money, money to be the amount of clearance events, set time, set time, set up the balance sheet date. Real Time Clock hardware clock circuit, with temperature compensation to ensure the time error less than 0.5s / d. Communication Interface Have two RS485 and a infrared communication interfaces. The three interfaces are completely independent, and can work at the same time. In line with the communication protocol DL/T645-1997 Multi-function watt-hour meter, or other statute in users requirement. Electricity Meter Reading Meter equipped with an independent battery, through power button or infrared can do infrared meter reading after the wake-up call. Power Freeze By radio command to freeze all consumption, and also the whole point of freezing, the whole point of the freezing time can be set up. can selecte Dingxin, Xiao Cheng, Neusoft carrier modules according to user requirements.
