Replacement Ammeter for Magnaflux/Arga 22-045

Replacement Ammeter for Magnaflux/Arga 22-045

FWDC / HWDC & True RMS AC Ammeter

AC/DC Panel Mount Replacement Shunt Ammeter

The SI-19KA/ACDC/1/8 DIN Digital Panel Meter is designed to replace the original Arga 1/8 DIN size ammeter. It fits directly into the existing panel; its rear panel block has 2 jumpers that control mode selection of either AC, FWDC and HWDC. The high visibility LED digital panel meter displays the output current in kilo amperes. The meter holds this reading indefinitely for accurate recording of the last mag current shot. As each mag shot is taken, the meter will automatically reset, compute and display the new reading in less than .5 seconds.


  • Meter gain calibration adjustment on the front panel
  • Direct replacement for mag units
  • Holds last reading or can perform continuous readings
  • LED Display, 3.5 digits
  • Mounting Clamps for front panel
  • Front panel face plate option in 4" x 4"
  • AC power input terminals
  • Shunt input terminals
  • Reads up to 19990 amps


Standard Meters are both TRUE Average DC and TRUE RMS AC calibrated for operation from your existing 50mv/1000 Amp meter shunt either in place or in conjunction with your machine's meter. Meters are pre-calibrated, and there is an external gain adjust in case you need a minor trim due to your existing meter shunt accuracy. This ammeter will take the true DC average of any DC waveform, whether it is 1 phase FWDC, HWDC, or 3 phase 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.
