The Smart Circuit 20 allows you to take control of your electricity consumption, access data, switch loads, reduce your carbon footprint, lower your energy bill, and automate load shedding and KWH reduction via a user-friendly web interface. The Smart Circuit has been specifically designed for permanent hard-wired applications on 100V-250V, 20A, 50/60Hz circuits. It is a sophisticated, scalable, yet affordable energy management system ideal for sub-metering, remote monitoring, and automatically reducing electricity consumption in residential and commercial applications. The Smart Circuit will automatically output live data (as fast as every second) which can be viewed in table format, in a graphical display, or it can be downloaded as a csv file. Smart Circuits are ideal for lighting circuits, outlet circuits with lots of vampire or leaker loads, large hard-wired appliances such as electric hot water heaters, washer/dryers, HVAC systems, pumps, blowers, and refrigerator/freezers. Smart Circuits are also ideal for home automation projects where it is important to remotely turn things on or off. Smart Circuit 20 interfaces to a PC via a USB connection, and to a network via an integrated Ethernet jack. Fast, intuitive and easy-to-use, Smart Circuit 20 quickly and accurately measures 100 - 250 VAC, 50/60 Hz, 20 amp circuits.Typical UsesSmart Circuits are ideal for lighting circuits, outlet circuits with lots of vampire or leaker loads, large hard-wired appliances such as electric hot water heaters, washer/dryers, HVAC systems, pumps, blowers, and refrigerator/freezers.
