Volt Meter

The Trumeter APM Voltmeter is ideal for engineers, panel builders and designers who want a more effective way of displaying and monitoring voltage.

Trumeter APM digital panel voltmeter


The APM panel mounted voltmeter features an auto-detecting AC or DC measuring input, capable of measuring up to 600V to an accuracy of 1%. It comes with a range of built-in features and the digital LCD display provides immediate and accurate visual indication of critical parameters from almost any angle.


The next generation of digital panel voltmeter

The APM digital panel Voltmeter boasts a flexible voltage measuring input capable of measuring both AC and DC voltages. It is simple to install and easy to use, automatically detecting AC or DC signals and boasting input ranges of up to 600V.

The output models include two separate digital (open collector) or analogue (4-20mA) outputs. These outputs allow the user to interface the voltmeter with:


– Beacons

– Sounders

– Indicators

– PLCs

– Remote monitors

– Interlocks, relays and more.


It is an ideal panel voltmeter for a range of applications, making potential voltage alerts unmissable and monitoring more effective.


Programmable, panel mount voltmeter

The programmable voltmeter scale allows the user to set the bar graph to their own specifications by entering minimum and maximum values. Centre zero, positive and negative scales, as well as customised set points and alerts, are all user-programmable via the APM’s configurator software.

For convenience, the digital panel voltmeter also comes with 15 built-in configurations for use straight out of the box.


Unique digital display

The APM voltmeter’s unique LCD display, with adjustable backlight brightness and positive or negative screen options, provides better visibility than any other product on the market. The wide viewing angle makes readings visible from almost any perspective.

No other panel voltmeter combines the instant recognition of an analogue coil/traditional panel meter with the precision and accuracy of digital panel voltmeters. As well as alerts via colour change and flashing, the starburst display area allows for any annunciators, custom messages and/or alarm information where it may be required. The 40-segment bar graph provides instant display of readings with large, easy-to-read starburst display for complete clarity.
