Prepayment Single phase Types of Electricity Meters

General Introduction Electronic Single phase Energy Meter adopts the most advanced professional measurement chip and many international famous industrial components. It has many advantages: accurate measurement, reliable operation, lower start current and energy consumption, no need shunt running and can measure the used power even meter is on reversing connection. It has stable long service life and smart figure, light and easy to install. It can resist electromagnetic interference and can work under harsh electricity environment.
