KW8M Eco-POWER METER 1A/5A CT Input type Visualization Toward energy savings Makes us more ecological! Direct input of secondary side 1A/5A CT Direct input from “secondary side 1A/5A” type domestic and overseas CTs. Dedicated CTs are no longer needed, which lowers the cost of implementation. High current circuit measurement Even for high currents that exceed 400 A on the primary side, a wide range of currents up to 4,000 A can be measured using a CT with secondary side current 1A/5A. KW8M Eco- POWER METER (1A/5A CT Input type) AKW8115 Available from: May 2010 400 V and Three-phase four-wire system With 400 VAC Transformer-less input possible, it is compatible with three-phase, four-wire systems. Direct connection is possible to the dynamic power systems of large-scale factories and buildings. Pulse measurement and Networking Carried on from the standard KW8M specifications, features such as simultaneous pulse measurement, networking and the notification function are provided. -year warranty 2010.5 panasonic-electric-works.net/ac 05/2010
