DTSD311 трехфазный электронный МНОГОФУНКЦИОНАЛЬНЫЙ ВАТТ

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. 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. Load Curve Forward, reverse active power one point per 15 minutes, save the last six months of data. 2M-byte maximum storage space, record data can be set according to user requirements. 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. Standby Power Equipped with standby power, can read meter through the RS485 port, and to ensure the meter normal work. Variety Means Of Defense Electric Larceny With the logic lock function, able to judge the state laboratory, non-laboratory status. Detection of multi-level password, set up to prevent illegal. Scalable open casing, lid switch detection start button. GPRS communication module can be configured into network of multi-function meter.
