Overview

  GV25 MKII is an upgraded product of our company's GV25 digital display meter. It is a lightweight, low-cost module used to measure and display AC voltage, frequency, current, power, power factor, and accumulated operating time. It can replace the traditional pointer. type instrument, realizing one meter for multiple purposes.

    This series of instruments has two models:

    GV25 MKII: equipped with a current transformer with a secondary of 5A;

    GV25L MKII: equipped with a current transformer with a secondary of 50mA.

Features

  After installation, the panel reaches IP54 protection level;

  Able to measure and display voltage, frequency, and current simultaneously;

  3-digit high-brightness LED digital tube displays the measured value;

  The current transformer ratio can be set;
