    Constant Wattage Autotransformer (CWA) Ballast

    Monday, February 9th, 2009

    Constant Wattage Autotransformer (CWA) Ballast is a magnetic ballast (i.e. T12 Ballast) transformer ballast circuit that has a capacitor in series with the light bulb; compared to many other ballasts, the Constant Wattage Autotransformer regulates over a greater input voltage range, making the lamp current nearly constant.
