Tips: What is a 3 phase digital ampere meter?
The three phase digital ampere meter is used to set the CT parameters through the panel buttons to visually display the system's one-time operating current. The three rows of digital tubes simultaneously display the 3 phase AC current value. The LED or LCD display is clear and high precision. This panel ammeter can replace the traditional analog pointer meter with RS485 interface and analog quantity, upper and lower limit alarm function, convenient for data exchange with microcomputer, PLC, etc., which is a high performance automation instrument and suitable for modern power supply and distribution systems such as industrial and mining enterprises, civil buildings, and building automation.
Digital display panel ampere meter can measure 3 phase AC current 1A ~ 5A in three phase electric network with high accuracy, monitor analog input and switch input, different panel size for your choices and selectable LED or LCD display.
