The E-Mon D-Mon Class 2000 three-phase kWh meters are fully electronic, low cost meters for monitoring electrical usage in commercial, industrial or institutional facilities. E-Mon's patented 0-2 volt output split-core current sensors allow for quick and safe installation without power interruption. These sensors also allow for meters to be remotely located up to 2,000 feet from the electrical panel they are monitoring. Multiple sets of sensors can be installed on one meter to provide cumulative usage readings for multiple loads.
