Product Details: Product Name: Clou DSSD718 three-phase three-wire electronic multi-function meter accuracy level: 0.5S level, 0.2S grade wiring system: three-phase three-wire voltage specifications: 3 * 100V current specifications: Transformer Access type: 0.3 (1.2) A, 1.5 (6) A, 5 (10) A, 5 (6) A straight-through: 10 (40) A, 15 (60) A, 20 (80) A major characteristic: the use of advanced DSP ( digital signal processing) technology and unique real-time high-speed power algorithm under load fluctuations, high harmonic content of the operating conditions can still ensure accurate energy measurement. Measure A, total harmonic distortion B, C phase voltage and current harmonics and 2 to 31 and containing 2 to 31 times the rate of harmonic current value. Referring to GB / T / 14549-93 (power quality utility grid harmonics) standard, and 2-16 on the total harmonic voltage and harmonic current monitoring When monitoring the amount exceeds the limit, the meter super harmonic limit state and harmonic gauge recorded events. Main features: hourly metering forward and reverse active energy active; hourly metering forward and reverse reactive reactive power, reactive power forward and reverse reactive energy metering mode can be set; hourly metering four quadrants reactive energy. 1, positive and negative active hourly metering maximum demand, positive and negative reactive power maximum demand and four quadrant reactive maximum demand. 2, can be set to 10 kinds of rates, 14 time zones, 12 sets of day time table, 14 hours, 13 holidays, weekly rest days and holidays can be pre-set time table different day. 3, accurate measurement of the phase and total active power, reactive power, power factor, phase voltage, current and phase, and frequency and other electrical parameters. 4, the measurement of total harmonic distortion A, B, C three-phase voltage, current and two to 31 times harmonic ratio. 5, pressure loss record: Record months phase and total loss of pressure accumulated time. Each phase has recently recorded ten times the loss of pressure occurs in time, end time, electric energy is lost during compression. 6, record the last ten demand clear, programming, phase failure, overvoltage, loss of pressure, loss of flow, reverse phase sequence, overload, current imbalance, school, power-down, power-on and other events. 7, load monitoring: When the load exceeds a set value, you can set the audible alarm and relay output. 8, the power to freeze: freeze all electricity via broadcast commands can also freeze the whole point, the whole point of freezing time there are four groups. 9, load curve: select multiple sets of data in different or the same interval (1 to 1440 minutes Optional) scrolling data records. Recorded with time stamp (month, day, hour, minute), total storage space of not less than 2M bytes. 10, power meter: After a power outage, Wake meter by meter infrared or infrared wake button. 11, calculate the voltage passing rate, phase voltage passing rate recorded in the last four months. 12, with RS485 communication port and an infrared communications port. 13, active and reactive pulse optocoupler output, real-time clock pulse optocoupler output, two programmable relay outputs. 14, LCD character display various parameters and measurement data. 15, three-phase power supply, as long as there is a phase voltage to ensure that the meter is working properly. 16, case selection of the latest international BMC composite materials, arc-resistant, UV resistant, flame retardant completely.
