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, and the average value. It is displayed by 5-row 4-digit LED. The instrument can also be installed by different function modules to support the analog quantity, higher or lower alarm, and RS485 communication function.
