Janitza UMG 604-PRO Power Quality Analyser 24 V 5216222

Power quality issues like harmonics, voltage sags, and transients can cause equipment failure and downtime. The Janitza UMG 604-PRO is a panel-mounted power quality analyser that continuously monitors and records these parameters to help you maintain reliable electrical systems.

Who is it for

Electrical engineers, facility managers, and energy consultants who need precise, standards-compliant power quality data for troubleshooting, audits, or permanent monitoring in industrial and commercial installations.
