Product Description

Chapter 1. General introduction

The instrument can measure all common parameters(voltage, current, frequency, power, power factor) in power network and display through 3-row 4-digit LED digital tube with an indicator light or LCD screen. The instrument can also be installed by different function modules to support the analog quantity, higher or lower alarm, and RS485 communication function.
On this basis, the LCD meter has increased the measuring and display functions of the demand value, the max./min. value, and the average value.

Chapter 2.Model and definition



Chapter 3.General parameters

Note: 1. When the shape is 2 or 9, they are with four-channel of switching input DI.
          2. When the shape is 3 or 7, they are with two-channel of switching input D1. (there are with no switching outputs when the output function code is D, M, N or S)
          3. When the shape is 3 or 7, there are with no electric pulse outputs. (can choose the electric pulse to instead of the two-channel of switching input D1)
