Ail Efficient . Dependable Power Supply for Your Projection Arcs There's a National Rectifier designed to match the requirements of every type and rating of angle trim or coaxial trim projection arc lamp. All are built in single lamp units for flexibility of electrical connection. Power output adjustment to the arc , over a wide range of values while the arc is burning, is by means of an external, manually operated hand wheel on the front. Transformer taps are provided to compensate for changes in line voltages from 200 to 250 volts and the complete amperage range. SELENIUM PIATE TYPE.., A full metallic, heavy duty equipment for converting three-phase A.C. to D.C. for operating arcs of from 60 to 1 35 amperes. Models in four capacities, adjustable from 60 to 75 amperes, 70 to 90 amperes, 80 to 1 1 0 amperes, and 90 to 1 35 amperes. Reliable operation in damp climates. Fan ventilated. No warm-up period required. TUBE TYPE... Six models, for use with high intensity arcs for either three-phase or single-phase operation on 230-volt, 60-cycle power service. Amperage ratings: 40, 50, 60-70, 70-85, 75-90. The housing assures ample draft through the transformer assembly and past the rectifier tubes to maintain low operating temperatures.
