  • Introduction
  • Specifications
HR series of AC thermal measuring controller, use full isolated technology, directly collect voltage and current transformer signal, calculated frequency, voltage and current, and phase difference and single-phase active power P=U.I.CosΦ or three-phase active power P=√3×U×I×COS(φ+30）, Formula of reactive power: reactive power= Apparent power- active power
specific integrated chip, with reliable anti-jamming and stable function
can modify display range, transmission range, alarm value and alarm mode online
soft, hard ware combined anti-jamming type, reduce field jamming signal efficiently
Digital calibration technology
Isolated light and electric technology
With RS232 or RS485 communication function, use standard MODBUS RTU protocol
