The three-phase voltage and current combination meter is a multi-functional electrical measuring instrument with programmable measurement, display and digital communication functions. It can complete electricity measurement, data display, acquisition and transmission, and can be widely used in substation automation, distribution automation, intelligent buildings , Electric energy measurement, management and assessment within the enterprise. The measurement accuracy is 0.5 level, and the MODBUS-RTU communication protocol is used to realize LED on-site display and remote RS-485 digital interface communication.


Measurement: three-phase voltage, three-phase current
Display: three rows of LED digital/LCD liquid crystal display, visibility
Communication: RS485 communication, MODBUS-RTU protocol
Input: 4-way switch input
Output: 4-way switch output
Expansion: The signal can be directly accessed from the current and voltage transformers, and the input parameter transformation ratio can be set programmable in the field
Uses: It can be widely used in substation automation, power distribution automation, intelligent buildings, and power measurement, management and assessment within enterprises.
