Power network meter with Modbus RTU (RS-485) protocol



The ND31LITE network parameter meter, has been designed specifically for applications requiring high-quality measurement equipment that will provide the customer the ability to monitor network parameters via the popular and reliable RS-485 interface with MODBUS protocol.

The meter measures 54 parameters, including current and voltage harmonics up to 63rd in 1- and 3-phase networks. Energy measurement is carried out in the 0.2S class, which significantly distinguishes the ND31LITE in this class of devices.  

In addition to the measurement functions, the ND31LITE is equipped with a function for storing extremes, so you can always check the minimum and maximum values of the measurement.
Another advantage of the device is an easy-to-read display with multiple confgurable visualization screens and easy parameter programming with the free eCon software.
