Product Details

Product Overview

TN1VT series multi-functional power meter is a multi-functional power meter with programmable measurement, display, digital communication power pulse, transmission output and other functions, which can complete power measurement, power calculation, data display, collection and transmission, and can be widely used in substation automation, distribution automation, intelligent building, internal power measurement, management and assessment. The measurement accuracy is 0.5 class, and the LED/LCD field display and remote RS-485 digital interface communication are realized, and the MODBUS-RTU communication protocol is adopted.

Peculiarity
