ALTA Industrial Wireless Three Phase Current Meter – 150 Amp

he ALTA Industrial Wireless Three Phase Current Meter (150 Amp) measures the RMS current of an alternating current (AC) system using 3 current transformers (CTs) that wrap around the wires of a three phase power system.The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and duty cycle for each phase and the combined amp hours of all three phases to the iMonnit system.

Information

The ALTA Industrial Wireless Three Phase Current Meter measures the RMS current of an alternating current (AC) system using 3 current transformers (CTs) that wrap around the wires of a three phase power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and duty cycle for each phase and the combined amp hours of all three phases to the iMonnit system. The iMonnit system is capable of generating watt hour or kilowatt hour readings as well based on a user specified RMS voltage.

  • Measures amp hours, max RMS current, min RMS current, average RMS current, and duty cycle for each phase and combined amp hours from all three phases 
  • 3 x 0-150 amp current transducers 
  • Capable of generating watt hour or kilowatt hour readings using iMonnit
  • Data logging for accumulated amp hour readings 
  • Can notify based on current levels 
  • Simple and safe installation of current/power measurement hardware, no rewiring required

To measure current, clip the CT around only a single wire of a powered system (clipping around a hot and neutral wire at the same time will result in 0 current readings). After the sensor powers on and connects to the gateway it will begin taking measurements based on the averaging interval (5 seconds default). It will report data to iMonnit every heartbeat or if the current goes outside of the aware thresholds set in iMonnit. The sensor reports average current, max RMS current, min RMS current, and duty cycle for each phase and amp hours for all three phases combined. iMonnit can also generate watt hour or kilowatt hour readings if a default RMS voltage is set in iMonnit.

* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables. Other power options are also available
