4QD-VTX-40-12 4QD-VTX-40 12V Speed Controller
<p align="left"><font face="Arial, Helvetica, sans-serif" size="2"> <font color="00ff66">4QD's
'VTX' series are full feature Four Quadrant (acceleration and regenerative
braking, forward and reverse) motor speed controllers for 12v-48v
battery operation. The range is economical enough for toy cars and
robots, yet powerful enough for use in golf buggies so it provides
a very cost-effective solution for virtually every application which
requires a reversing motor controller in the current range up to
100 amps.</font></font></p>
<p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif"> Some
possible applications are:- robots, scooters, golf buggies, miniature
railways, kiddiecars, floor cleaners, caravan shifters and vehicle
loaders. The VTX-40 is the baby of the range, covering currents up
to 50 amps. For more demanding applications the VTX-75 will give
currents up to 100 amps. For applications such as heavy golf buggies
which use two motors, two controllers can be coupled so the two motors
work as one, but with independent current limiting, giving control
of currents up to 200 amps. This feature is also popular with miniature
railways where two engines are 'double headed'. All models are available
in 12v, 24v, and 36v versions</font></p>
<p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif"> The VTX series are based on our tried and tested NCC series and are
technically advanced and packed with useful features without the 'high
tech overkill' which is often used as a sales gimmick. The controllers
have been extensively 'value engineered' to give the best possible
ratio of performance to cost. Of special interest are the independent,
linear, adjustable acceleration and deceleration ramps, the 'dual ramp'
automatic reversing, the thermally sensitive overcurrent limiting,
the regen current limit, pot fault detection, ramp down at power off,
reversing at zero demand speed and automatic reverse speed reduction.</font></p>
