Monnit Wireless 20 Amp Three-Phase Current Meter

Monnit Wireless 20 Amp Three-Phase Current Meter

The ALTA Industrial Wireless Three Phase Current Meter measures the RMS current of an alternating current (AC) system using 3 current transducers (CTs) that wrap around the wires of a three phase power system.

• 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
• 3x current transducers
• Capable of generating watt hour or kilowatt hour readings using iMonnit
• Data logging for accumulated amp hour readings
• Can notify based on amperage/power levels
• Simple and safe installation of amperage/power measurement hardware, no rewiring required

• Wireless range of 1,200+ feet through 12+ walls1


• Frequency-Hopping Spread Spectrum (FHSS)


• Best-in-class interference immunity


• Best-in-class power management for longer battery life2


• Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)


• Data logs 2000 to 4000 readings if the gateway connection is lost (non-volatile flash, persists through the power cycle): 10-minute heartbeats = ~ 22 days - 2-hour heartbeats = ~ 266 days


• Over-the-air updates (future-proof)
