MUM400 series multifunctional power measurement device

Product Introduction

The MUM400 series products mainly provide a universal and multifunctional intelligent solution for high and low voltage distribution systems. By measuring over 50 electrical parameters in the distribution system (such as maximum, minimum, average, and harmonic components of current, voltage, frequency, power, power factor, energy, etc.), the distribution system can be monitored. In addition, functions such as transmission, fault recording, statistics, and communication can be used to help customers comprehensively analyze and manage the operation of the distribution system, providing reliability and efficiency of power supply.

The MUM400 series is divided into two products: MUM430 and MUM450.
