Itokii wireless AC Current Meters measure the RMS current of an alternating current (AC) system using a current transformer (CT) that wraps around the "hot" wire of a two wire (hot, common, ground(optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours to the Itokii system. The Itokii system is capable of generating watt hour or kilowatt hour readings as well.
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 3.0 - 3.6 V power supply (Included with Line Power option upgrade). 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.
WARNING: This AC current meter is for monitoring AC voltage only. Do Not Use with DC voltage.
- Measures amp hours, max RMS current, min RMS current, and average RMS current.
- Capable of generating Watt Hour or Kilowatt Hour readings using Itokii.
- Data logging for accumulated amp hour readings.
- Can notify based on current levels or changes in current levels.
- Measures current from 0 - 20 Amps.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
