Product Description

Chapter 1. General introduction

On the basis of the conventional multifunctional network power instrument, it is added the measuring and display functions of the demand value, the maximum and minimum value, the average value, and the voltage and current harmonics (the total harmonic distortion rate, the odd/even harmonic distortion rate, the 2nd ~ 21st harmonic wave ratio). It is displayed by 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.

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)
