DC digital ammeters and voltmeters are available in two DIN sizes, 48x24mm and 96x48mm, both featuring a 3½ digit red LED display. The meters panel mount and offer a wide choice of input and display options making them suitable for a large range of industrial applications. All DC digital panel meters can be powered by a large selection of self contained AC or DC auxiliary power supplies, which all offer isolation between the measured input signal and auxiliary supply voltage. All DC digital panel meters are delivered fully calibrated, however adjustments to zero and span points can be made. Optional terminal protection covers are also available.
