Boyer Dynamo Regulators
332-Series
The dynamo regulator unit is designed to replace the mechanical voltage
regulator and cut-out used on many motorcycles using the LUCAS E3 TWO BRUSH
DYNAMO. It will also replace the electronic aftermarket direct current regulator units.
The dynamo regulator unit uses a very efficient switching device controlled
at over 500 times/sec., it's on/off ratio is adjusted electronically by a
circuit measuring the dynamo voltage, this switch controls the magnetic
field of the dynamo stator without the power loss in the stator coil winding
present with a normal direct current system.
Also incorporated is a method
of maintaining the magnetic field when the switching device is in the off
condition. This control is so good that even without a battery, lighting
circuits and horn can be run direct form the dynamo without flicker.
(Ignition can only be fed when a battery is fitted as no voltage is
available at kick-start speeds).
Made In England
With a 6 volt system, charging will start at 1200 RPM; on a 12 volt system
1600-1800 RPM is required. Reduced output voltage will be available from 500
RPM upwards. If lighting is run direct without a battery then the bulbs will
be at half brilliance at tick over and full output at 2500 RPM.
Battery charging is by voltage control with current regulation, if higher
charging currents are prolonged. Stability is maintained by internal
thermistor control.
A dynamo that has been rewound for 12 volts will start charging at a lower
RPM and will work well with this unit.
Size: 2-1/2" by 2-1/2", with 1-1/2" height. 1/2 inch flanges. Weight: 200
grams. 4 x 6mm mounting holes. The later large Lucas voltage control cover
can be fitted over the regulator box to give an original appearance. If you
wish to run the earlier small Lucas regulator cover, please see our
Podtronic dynamo regulators, which are smaller, but only are currently
available in 6V.
