rs485 power factor meter
  1.Function:   rs485 power factor meter Measure and digital display on single-phase/three-phase power factor or phase value of electric wiring. The power factor meter can see the frequency and phase value, and phase meter can see frequency and power factor value through the keyboard. Switching value output (higher and lower  limit alarms) modules, analog value transmitting output module, RS485 communication module are optional offered.     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.   2.Technical Parameter:   rs485 power factor meter
    3.Basic parameters:   rs485 power factor meter Power factor measurement display range: 0.001L~0.500L~1~0.500C~ 0.001C Phase measurement display range:0°~359.9° Frequency measurement display range:45.00~65.00Hz Accuracy of power factor measurement:±0.01; Accuracy of phase measurement:±1°; Accuracy of frequency measurement:±0.1Hz Resolution:Power factor display resolution is 0.001,          frequency display resolution is 0.01Hz,          phase display resolution is 0.1° Sampling rate:About 2.5 times /sec. Rated input voltage:AC100V±10%, 220V±10% or 380V±10%. Input current:1A~5A. Auxiliary power supply:AC/DC 85~264V. Alarm Output: relay contact output, the contact rating is AC250V/1A; Communication port:RS485 serial communication,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)   4.Terminal arrangement and wiring connection:   rs485 power factor 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     5.Typical connection:   rs485 power factor meter
