' HIGHER EFFICIENCY

A NEW AUTRASTAT DIMMER ' EAS'ER OPERAT'ON

' LESS SPACE New Radial Type Autrastat Dimmer for Theatre Lighting Control - LOWER MAINTENANCE

has all the characteristics of the rectangular type Autrastat, such as continuous duty at any setting, lamp voltage independent of load, uniform dimming curve, low core loss, and low operating temperatures (eliminating any necessity for special ventilation or cooling apparatus).

A number of new features have been added, however, which make the Radial Type Autrastat the most flexible, efficient and reliable dimmer for manual or remote motor operated applications. New metal base plate provides a rigid, substantial means of mounting. Toroidal core and coil further reduces core losses and provides higher eEiciency. Large solid brass contacts give greater capacity (better commutation without oxidation). Multiple shoe construction of silver graphite - self-lubricating and self-cleaning - assures good arcless contact. Oil-less center bearing reduces operating torque to a minimum and lowers maintenance.



Available in capacities up to 8000 watts in a single unit.
