Hoyt TWO-VUE switchboard meters are combination Digital/Analog indicating instruments.
They can be configured to accept VAC*, AAC*, VDC, or ADC input (* External transducer required).
Both the digital and analog displays can be modified to represent virtually any scaling or engineering units as required.
The unit is contained in a 4-1/4” switchboard housing.
It utilizes a pivot and jewel moving element and a 0.56”, 3-1/2 digit display for indication (±1999 counts).
Analog and digital display to provide the ultimate in readability of power and control parameters.
Drop-in replacement for upgrade of existing controls and switchgear panels.
Rugged switchboard style case and IP54 rated cover.
High-intensity LED digital displays with high reliability analog movements.
Standard models for DC voltage and current, with custom scales and dials available as options.
Scaling options are limited only in that there can be no offset zero scaling for the digital display.
