The CCR maintains the output current within the limits of Table 2-8 for all brightness steps when the load is connected via isolating transformers, and the secondaries of 50 percent of the transformers become open-circuited. The load before opening the isolation transformer secondaries may be any value from half to full load. For regulators less than 10 kW loaded as specified above, the current remains below 6.8 amperes for the 100 percent brightness step.
