Product overview
KY-5000 series products can measure all the common power parameters, such as three-phase current, voltage, active power, reactive power, quantity of electric charge, harmonic wave, etc., and has perfect communication networking function. It has RS-485 (Modbus RTU) data communication mode, and forms a remote monitoring system with the server to realize real-time data monitoring and realize tele-signalization, telemetering, telecontrol and other functions, which is very suitable for real-time power monitoring system.
The meters of this series can directly replace the auxiliary units related to power transmitter and measuring indicator light. Through the selection of function and scalability module, it can realize digital communication, transmission and functions of YX, YC, YK and YT. It has been widely used in high, medium and low voltage switch cabinet, distribution (metering) box and other power equipment, integrated into various control systems, SCADA systems, to achieve remote meter reading and other energy management functions.
