Product Details: Product Name: Terry McNair DSSD876 three-phase three-wire electronic multi-function meter accuracy level: 0.2S level, 0.5S level, a wiring system: three-phase three-wire voltage specifications: 3 * 100V current specifications: Transformers Access type: 1.5 (6) A straight-through: 0.3 (1.2) A ~ 30 (100) A full product description: DSSD876 multifunction meter performance indicators in line with GB / T17215.322-2008 "AC measuring equipment - Specific requirements Part 22: 0.2S and 0.5S grade level static active energy meter ", GB / T17215.323-2008" AC measuring equipment - Specific requirements - Part 23: 2 and 3 static reactive power meter "and DL / T 614-2007 "multi-function meter" standard, the communication line with DL / T645-2007 "multi-function meter communication protocol" requirement, and is compatible with the requirements of "multi-function meter communication protocol" of DL / T645-1997, according to functional customization requirements comply with the technical requirements of multifunction energy meter. Partial view of the main features: 1. measurement functions: time-measurement, the reverse of active and reactive power and maximum rates for each power demand and time of occurrence, and a combination of time-measurement quadrant reactive 1/2 maximum demand and occurrence time, measuring the total active and reactive energy, quadrant reactive total energy and A / B / C phase power, and store the current, the data on a settlement date ~ 12 settlement date. 2. The multi-rate features: Programmable 4 kinds of rates, 14 time zones, eight days time table; 14 hours, public holidays can be set to 254 and has a calendar, time and annual automatic switching function 3. Display: Backlit LCD, with parameter auto rotate, key display 4 Communication: RS485 interface has an independent and an infrared communications port, the two sides communicate simultaneously without disturbing each other. 5. Output function: there is no power test pulse output with multi-function output function can be realized 1Hz clock signal replacement demand period, period of the switching signal output function; 6. Event record: 1) real-time measurement of A, B , C-phase voltage, current, power, etc. and RMS current frequency; 2) has lost pressure, phase loss, loss of flow, total loss of pressure, voltage, reverse phase sequence, undervoltage, overvoltage, overcurrent, stop, current unbalanced, overload, total power factor over limit, stop calls, programming, demand clear, such as school record. 7. Special Function 1) has a power button or infrared wake function, and after a power outage can wake infrared meter reading; 2) has a fault message, alarm (LCD, alarm lights) function; 3) with timing freeze instantaneously freeze, agreed to freeze Japanese freeze and freeze the whole point of the function; 4) meter cleared before the data recording function; 5) password lockout feature: password authentication error after 5 meter will automatically lock 24 hours. 6) Auxiliary power failure recording function; 7) Optional load curve recording function; 8) Optional harmonic content measurement functions; 9) openings record.
