The JSY-MK-339 three-phase voltage and current collector is a three-phase power quality detector developed by our company using microelectronics technology and dedicated large-scale integrated circuits, digital sampling processing technology and SMT technology and other advanced technologies with completely independent intellectual property rights. The technical performance of the detector is in full compliance with the relevant technical requirements of the 1 class three-phase active energy meter in the IEC 62053-21 national standard, and can directly and accurately measure the voltage, current, power, power factor, electricity and total electrical parameters in the three-phase AC power grid with a rated frequency of 50HZ or 60HZ. The collector has 1 channel RS485 communication interface, and a MODBUS-RTU communication protocol to facilitate connection with various AMR systems. It has the characteristics of good reliability, small size, light weight, beautiful appearance, and convenient installation.
JSY-MK-339 three-phase voltage and current collector can be widely used in energy-saving transformation, electric power, communication, railway, transportation, Environmental protection, petrochemical, steel and other industries, used to monitor the current and power consumption of AC equipment.
