ProTAACS Wireless RF AC Current Meter - AA Battery Powered

ProTAACS Wireless RF AC Current Meter - AA Battery Powered

The wireless AC Current Meter measures the RMS current of an alternating current (AC) system using a current transformer (CT) that wraps around the “hot” wire of a two wire (hot, common, ground(optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours to the iProTAACS system. The iProTAACS system is capable of generating watt hour or kilowatt hour readings as well.

  • Measures amp hours, max RMS current, min RMS current, and average RMS current
  • Two different current transducers available:
    • Low Current: 0-20 Amp
    • High Current: 0-150 Amp
  • Capable of generating Watt Hour or Kilowatt Hour readings using iProTAACS
  • Data logging for accumulated amp hour readings
  • Can notify based on current levels or changes in current levels
  • Simple and safe installation of current/power measurement hardware, no rewiring required

  • 20 Amps
  • 150 Amps

* Hardware cannot withstand negative voltage. Please take care when connecting a power device.
** At temperatures above 100°C, it is possible for the board circuitry to lose programmed memory.
*** CTs are inherently less accurate at or below 10% of max range. For best results; calibrate at a current between 30% and 90% of max accurate range.
**** Offset is used to overcome a diode voltage drop inherent to the hardware. To accurately account for this drop a default offset is used. To best identify the optimal value of this offset; make a series of measurements at .2 to 2. Arms and find the current (Arms) difference between your measurement standard and the ProTAACS sensor.
