It differs from the Type DC1A model only in the voltage regulator output limits, which are now proportional to terminal voltage <i>V</i><i><sub>T</sub></i>. It is representative of solid-state replacements for various forms of older mechanical and rotating amplifier regulating equipment connected to dc commutator exciters.
