new three-phase wireless current meter

Salt Lake City, Utah – March 15, 2018 – Monnit Corporation ( today, announced a new wireless three phase current meter to help companies better track and understand power usage. The ALTA Three Phase Current Meter measures RMS current (AC) by using three 150 Amp 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 also capable of generating watt hour or kilowatt hour readings, based on user specified RMS voltage.

Features of the ALTA Three Phase Current Meter:

  • 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
  • Three 0-150 Amp current transducers
  • Industrial rated, waterproof sensor enclosure
  • 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

Monnit’s ALTA products offer four times the wireless range (1,000+ feet, non-line-of-site) and much stronger battery life than traditional sensors (10+ years on two AA batteries). ALTA products also use Monnit’s new Encrypt-RF™ bank level security, featuring 256-bit exchange and AES-128 CTR for all data messages.  Other features include; onboard memory for data logging if sensor is out-of-range, and over-the-air updates that allow products to be updated remotely if new fixes or features become available.

All of Monnit's wireless sensors include free basic iMonnit online sensor monitoring with SMS text and email alerting.  For more information on Monnit’s sensors, gateways and remote monitoring software, call (801) 561-5555 or visit

Monnit also provides products to OEM’s and Reseller’s through the IoTvantage™ business partner program which allows for volume discounts and private branding of both the wireless hardware and online monitoring software. Learn more at
