Monnit Introduces Industrial Wireless 3-Phase Current Meter—500 Amp

3 phase 500 Amp current meter

SALT LAKE CITYOctober 17, 2019 – Monnit Corporation ( today announced the release of the ALTA® Wireless 500 Amp Three Phase Current Meter. Designed to measure current drawn by a three-phase system, it installs in minutes via a three-wire clamping system. It monitors minimum current, maximum current, average current, duty cycle and combined amp hours.

“Most current meters store data locally, making it hard for companies to identify the power usage patterns of a machine or trends across multiple machines,” said Brad Walters, Monnit CEO. “With ALTA’s industry-leading wireless range to carry data—and new readings posted continuously in the online dashboard—businesses no longer need to be surprised by their power bills or worried about their equipment burning out without warning.”

Features of the ALTA Industrial 500 Amp Three Phase Current Meter:
  • Measures maximum, minimum and average RMS current as well as per-phase duty cycle and total amp hours from all three phases
  • Features three clamp-on 0-500 Amp current transducers (no rewiring required for implementation)
  • Can alert users if current levels are abnormal
  • Industrial-rated, waterproof sensor enclosure
  • Capable of displaying watt-hour or kilowatt-hour readings online or via Android and iOS apps
  • Provides data logging for accumulated amp hour readings
  • Can be utilized for real-time utility billing

Monnit’s ALTA products offer four times the wireless range (1,200+ feet, non-line-of-site) and much stronger battery life than traditional IoT sensors (12+ years on two AAs). Each of ALTA’s 80+ sensors features Encrypt-RF® bank-level security with 256-bit exchange and AES-128 CTR—keeping sensor data safe. Onboard data logging preserves data in the event of a communication outage. Over-the-air updates allow ALTA products to receive enhanced configurations and added functionality.

All Monnit wireless sensors include free basic online sensor monitoring with text and email alerting. For more information about SMB and Enterprise IoT solutions, call (801) 561-5555 or visit
