NOTE:
Degausser Current Consumption
The degaussing coils are powered as part of a tuned resonant circuit. This allows quite
high circulating currents to be generated within the degaussing coils, with minimal current
consumption from the mains voltage supply. However, this technique requires that the
waveform of the supply voltage contains minimal harmonic distortion. A distorted
waveform will result in an increase in current consumption.
The typical current consumption figures provided in this manual are when powered from a
supply with minimal distortion. Any increase in current consumption due to a distorted
waveform will have minimal effect on the degausser performance; however, excessive
current consumption should be avoided for obvious reasons. In the event of unexplained
high currents, please consult your supplier
.
TABLE 2
8.2 Current Monitor Test Points
The following table contains typical current values to be measured at specific points in the
equipment.
The values given are in amperes and may differ slightly from those actually measured due to
component tolerance plus effects due to operating temperature.
