MS2-9-W2-CM-020 Monnit Alta Wireless 20 & 150 Amp AC Current Meters

 Monnit ALTA 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 iMonnit system. The iMonnit system is capable of generating watt hour or kilowatt hour readings as well. For AC Current only do not use with DC current. The general purpose AA model should only be operated in dry, low humidity environments. Should you need a sensor that operates at extreme temperatures and can withstand getting wet or condensed on, please consider the IP65 NEMA 4X model.
