The power box is a self regulating rectifier with an internal current and voltage storing capacitor. Connecting directly to the
alternator the output is approximately 15 volts with no current being drawn and 14.5 volts with some load. These values
are just right for charging a 12 volt battery or running the electrics direct. The unit has been designed using the latest
power technology semi-conductors to provide stable, direct current from standard permanent magnet alternators. Three
types are available: Single phase, Bi phase and Three phase. In each case a charging lamp control, or lighting delay circuit,
which prevents the lights being turned on until after the engine is started, is available.
