Instruction Manual
VTX series controllers
VTX-40 and VTX-75
4QD try to write a manual which is readable. If we
succeed and you don’t read it there is not a lot more
we can do. However if you try to read it and don’t
understand it (or even don’t like our style) - then we
have failed so please tell us. Only by means of your
criticisms and suggestions can we improve our
publications! To help you, we have marked the more
technical sections ¶ so that you may ignore them.
If you have any problems or queries, 4QD pride
ourselves on our level of technical advice and if we
put as much information into this manual as we could
many would find it too long.
If you require more information, 4QD have a very
full WWW site which has a large section giving
answers to commonly asked technical questions.
Even if you do not have easy Internet access, you will
find this well worth reading, so ask a friend who is
connected or go to your local Internet Cafe or public
library.
4QD’s VTX range of economy 4 quadrant controllers
have been engineered to replace the NCC series. As
well as improved circuitry, they benefit from surface
mount technology, which offers superior reliability
and is better suited to higher volume production.
The VTX controllers are very suitable for general
purpose speed control applications where reversing is
required. Amongst other applications our controllers
have been successfully used in the following:
Camera dollies
Caravan shifters
Carnival floats
Conveyors
Factory stores vehicles
Floor cleaning machines
Golf buggies
Invalid scooters
Kiddie cars
Miniature railways, 3”, 5” and 7¼ gauge
Mobile targets
Mountain rescue vehicles
Remote controlled vehicles
Ride on golf buggies
Winches
In fact wherever battery motor speed control - and
good value - is required.
