UP 6760 

Model: UP 6760
Name: Multifunctional Power Quality Meter
Description: 
Overview

The UP 6760 Digital Power Meter is microprocessor-based instrument intended for power and energy measurement. Additional functionality options provide control functions such as synchro check. The UP 6760 is an Intelligent Electronic Device (IED) and stores these measured values and setting parameters in internal registers for communication. Featuring high accuracy, fully modularized & plug-in design, and compact size, the UP 6760 is very suitable for Electric Utility Substation Automation applications.
