The 12KW A.C. solid state electronic dimmer designed by Mole-Richardson allows motion picture studios to remotely dim lights at the fixture, rather than connections to rack mounted dimmers. The 12KW Dimmer will dim 0 to 12,000 watts of 120 volts A.C. from full intensity to complete blackout. This dimmer is especially useful in prolonging the life of large wattage lamps by preventing large inrush currents on a cold filament. The dimmer may be operated manually from a control on the dimmer or operated remotely. The dimmer output is fully protected from overloads and short circuits.
