Frequency Compensation
One or two jumper-selectable V/Hz curves with knee frequency adjustable from 45 to 65 Hz (50/60 Hz units) or
300 to 430 Hz (400 Hz units). Figure 2 illustrates the 60 Hz sensing model and Figure 3 illustrates the 400 Hz
sensing model.

EMI Suppression
Internal filter. (See CE Conformity)
Voltage Buildup
Automatic voltage buildup occurs from residual generator voltage as low as 6 Vac (AVC63-12) or 12 Vac
(AVC125-10).
Overexcitation Shutdown
Overexcitation shutdown protection reduces the output voltage to zero in the times shown below for the listed
voltages. Other voltages and times are based on the inverse time characteristic curves of Figures 4 and 5
