by The Leading Enterprise Internet of Things Solution Wireless 150 Amp AC Current Meters General Description Features of Monnit ALTA Sensors The ALTA wireless AC Current Meter measures the Wireless range of 1,200+ feet through 12+ walls * RMS current of an alternating current (AC) system Frequency-Hopping Spread Spectrum (FHSS) using a current transformer (CT) that wraps around the Improved interference immunity hot wire of a two wire (hot, common, ground(optional)) Improved power management for longer battery life ** power system. The sensor reports Minimum RMS (12+ years on AA batteries) current, maximum RMS current, average RMS current, Encrypt-RF Security (Diffie-Hellman Key Exchange and amp hours to the iMonnit system. The iMonnit + AES-128 CBC for sensor data messages) system is capable of generating watt hour or kilowatt All ALTA sensors now have up to 3200 readings: hour readings as well. - 10-minute heartbeats = 22 days - 2-hour heartbeats = 266 days Measures amp hours, max RMS current, min Over-the-air updates (future proof) RMS current, and average RMS current Free iMonnit basic online wireless sensor monitoring Two different current transducers available: and notification system to configure sensors, view Low Current: 0-20 amp data and set alerts via SMS text and email High Current: 0-150 amp Capable of generating watt hour or kilowatt hour readings using iMonnit Actual range may vary depending on environment. * Data logging for accumulated amp hour readings Battery life is determined by sensor reporting ** Can notify based on current levels or changes in frequency and other variables. Other power options current levels are also available. Simple and safe installation of current/power measurement hardware, no rewiring required Wireless Range Comparison Wireless Range Comparison Principle of Operation To measure current, clip the CT around only a single Monnit ALTA wire of the AC 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 Monnit 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 Other Wireless Platforms sensor reports amp hours, max RMS current, min RMS current, and average RMS current. iMonnit can also generate watt hour or kilowatt hour readings if a default RMS voltage is set in iMonnit.

Please take care when connecting a power device. At temperatures above 100C, it is possible for the board circuitry to lose programmed memory. ** Power Options The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.03.6 V power supply. The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage. Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements. PAGE 2
