SiDE (Moving Iron AC Meter). The moving iron panel meters, DE 48/72/96/144 housed in moulded polycarbonate cases are suitable for the measurement of AC currents for frequency range of 15…400Hz and voltages in the frequency range of 15…100Hz.
Moving iron meters indicate rms-values practically independent of waveform even of high harmonics. Error of indication may occur for extreme waveforms (e.g. phase gating controls) & for frequencies above 100KHz.
These meters offer several advantages in switchboards and Generating Set Panels. Number of meters can be mounted in a Panel cut out Mosaic mounting). For CT operated ammeters, dials can be fitted based on CT ratio. Glass and bezel can be easily replaced.
