Three phase power Meter   Function:   Three phase power meter     Mainly used in the real-time measurement and digital indication on single-phase or 3-phase active(reactive) power   value in an electric circuit. It can be added modules such as Switching value output (higher and lower limit alarms)   modules,analog value transmitting output module, RS485 communication module are offered at the free option of   the user. It can conveniently realize the setting of many parameters including higher and lower limit alarm value,   alarm return difference, communication address and communication baud rate, transmitting output specification,   transmitting output range by the keyboard of instrument.   Technical Parameter:   Three phase power meter       Basic parameters:   Three phase power meter   Rated input voltage:AC100V,220V,380V (with programmable PT ratio) Rated input current:AC 1A or 5A(with programmable CT ratio) Measuring display range:0~999W~999kW~9999MW(units shift automatically through status light) or 0~999var~999kvar~9999Mvar (units shift automatically through status light) Accuracy rating of measurement:±0.5%FS±1digit(active power),  ±1.0%FS±1digit(reactive power) Resolution: top1W(or 1 var), the decimal point shift automatically Sampling rate:About 2.5 times /s Polar indication:can indicate backward power, negative signal displays“-”automatically Alarm Output: relay contact output, the contact rating is AC250V/1A Communication interface:RS485 serial communication, applying MODBUS_RTU communication protocol Transmitting output: can be set freely as DC0~10mA,0~20mA or 4~20mA,electrical isolation between the signal input and auxiliary power supply. Transmitting output load resistance:≤400Ω Switching value input: two-channel of passive contact input ( can customize four channels) Auxiliary power supply :AC/DC 85~264V     Terminal arrangement and wiring connection:   Three phase power meter     ( Attention: If it is not the same with the wiring schema of the diagram behind case, please accord to the one of diagram behind case)      POWER:Auxiliary power input port of instrument, Auxiliary power supply is AC 220V±10%  (please note if you need special power supply). INPUT:Signal input port of instrument, HI represents“+” port of DC input signal, fire wire terminal of AC voltage input signal and inlet wire terminal of AC current input signal. LO: “-” port of DC input signal, the other one wire of AC voltage input signal; the outlet wire terminal of AC current signal input  OUT:the alarm contact output port of meter     Typical connection:   Three phase power meter                     Factory:
