1.2.5 SNUBBER PC BOARD (10 through 510 and 550 ADC Power Converters only)
The SNUBBER BOARD (Figure 1-7) contains resistor/capacitor circuits for protection of
the SCR's. They are placed on a board instead of across the SCR's so they are not
misapplied when replacing an SCR. In units rated 540, 850, 1550, and 3000 ADC, the
snubbers are mounted directly to the thyristor module assembly.
