AC Voltage digital panel meters

The digital panel meters and controllers on this page accept AC voltages. All can be scaled to read in your preferred engineering units.

Suited to these applications and more:-

• Power voltage measurement
• Noise voltage measurement
• Backup generator monitoring
• Speed measurement from AC tachogenerators
• Any physical variable having a variable ac voltage

This page has 3 models for you to choose from:-
