JSY-MK-333 Three Phase Embedded Power Metering Module




Products Description




JSY-MK-333 power meter module introduce
JSY-MK-333 three-phase embedded power metering module that is developed by JSY Technology using microelectronics technology and specialized large-scale integrated circuits, applying advanced technologies such as digital sampling and processing technology and SMT process, and with completely independent intellectual property rights. The technical performance of this metering module meets the relevant technical requirements of Class 1.0 three-phase active energy meters in the IEC 62053-2 standard. It can directly and accurately measure the voltage, current, power, power factor, active and reactive energy and other electrical parameters in a three-phase AC power grid with a rated frequency of 50Hz or 60Hz. This module is equipped with 1 RS485 communication interface, 1 TTL interface, and sampling MODBUS-RTU communication protocol, making it easy to connect with various AMR systems. It has the characteristics of good reliability, small size, light weight, beautiful appearance, and easy installation.
JSY-MK-333 three-phase embedded metering module can be widely used in energy-saving transformation, EV AC charging station, power monitoring, communication, railway, transportation, environmental protection, petrochemical and steel to monitor the current and electricity consumption of AC equipment.
