PERFECT FOR UPGRADINGH YOUR OLD MECHANICAL CUTOUT ON YOUR OLD AUTOLITE OR SPLITDORF EQUIPPED iNDIAN This device is proven and reliable. Available in Negative earth, also to run a 6/12V V system. The dynamo regulator is designed to replace the mechanical regulator with modern reliable semiconductors, and can handle up to 100W at 6V and even more for the 12V version, provided the dynamo is capable of delivering this power. Fitted to the inside of a Miller regulator The regulator must be used with a good battery (minimum 5 Amp-hours) and is guaranteed, subject to correct fitting and use with a good dynamo. New features include: Current limit to the field winding, allows excellent performance when using a 6V dynamo on a 12V system while not straining the dynamo. Tougher electronics, with the introduction of higher energy spark suppression to reduce spikes generated by the dynamo. Improved "thermal foldback" which progressively reduces output power if the regulator gets too hot, indirectly limiting the dynamo from excessive current. Better servo loop stability, with new electronics which 'predict' when the output voltage is nearly correct and control the field current earlier. The REGULATOR will run a 6V system or by cutting a simple wire link will run a 12V system.
