4QD's Uni range of 1 quadrant and 2 quadrant speed
controllers are well suited to general purpose speed
control applications. They are used extensively by
hobbyists and industry.
Amongst other applications our controllers have been
successfully used in the following:
Camera dollies
Caravan shifters
Carnival floats
Conveyors
Electric boats
Electric bicycles
Electric wheelbarrows
Factory stores vehicles
Floor cleaning machines
Golf caddies
Kiddie cars
Miniature railways, 3", 5" and 7¼ gauge
Mountain rescue vehicles
Potter's wheels
Remote controlled vehicles
Ride on golf buggies
Winches
Window cleaning machines
Wherever battery motor speed control is required.

The Uni range controllers are protected so that voltage versions which can be changed by shorting such failure is very unlikely but the constructor out a resistor.

The controller mounts via the heatsink as shown in the diagram, right. Mounting will normally be onto a metal plate which will act as heatsinking.

Battery Condition Indicator A Battery Condition Meter can easily be fitted between pin A of the connector and pin d (green wire to pot) as shown left, below. If you want the ignition switch also to disconnect the pot, then the pot’s max connection can be connected from the battery positive, via the ignition switch as shown far right. - Page 7 4QD also manufacture reversing controllers such as However for fixed use, from a mains power supply, the VTX range.
