ADL400's three-phase energy meter is divided into direct current access and secondary current access. The wiring torque for direct access should be 3-4N·m, and the wiring torque for ct access should be 1.5-2N·m. The overall size of the meter is L*W*H: 90*72*65mm, the front panel has the corresponding silkscreen, including voltage input line, current input line, auxiliary function port number, LOGO, LCD display, buttons, etc. It can measure all power parameters, with 2~31 sub-harmonic and total harmonic content detection. With RS485 communication interface and optional MODBUS-RTU protocol, the power meter can be widely used in various control systems, SCADA systems, and energy management systems.
