4 Digit ARGA 22-045 Replacement Digital Ammeter


Replacement Ammeter for Magnaflux/Arga 22-045
FWDC/HWDC & True RMS AC Ammeter

SI-19KA/ACDC/1/8 DIN Digital Panel Meter designed to replace the original Arga 1/8 DIN size ammeter.

It’s a direct fit, slides right into existing panel. It has rear panel terminal block, where 2 jumpers control mode select of AC,FWDC,HWDC.

High visibility LED digital display shows the output current in kilo amperes. The meters holds its last reading indefinitely for accurate recording of each mag shot. As each mag shot is taken the meterwill automatically reset, compute and display the new reading in less than .5 seconds.

Standard Meters are calibrated for both TRUE AVERAGE DC and TRUE RMS AC ,for operation from your existing 50mv/1000 Amp meter shunt either in place of or in conjunction with your machine’s meter. Meters are pre-calibrated, and there is a external gain adjust in case you need a minor trim due to you existing meter shunt accuracy. This ammeter will take the true DC average of any DC waveform, whether it is 1 phase FWDC, or HWDC, or 3phase FWDC, without having to re-adjust again the gain setting. This meter also reads the TRUE RMS AC current of any AC waveform, regardless of crest factor.
