Model 33 spellers are designed for applications where electric circuits are to be flashed in custom sequences such as with spelling or other animation. Variable in both cycle speed and cam cut, model 33 spellers are some of the most versatile sign controllers available. The flashing sequence on each model 33 speller is custom made to customer specifications. The units can be built with as few as one circuit or as many as necessary to accommodate the requested flashing sequence. Neon can be controlled by installing the speller on the primary side of transformers.
