4QD Pro 120 Series

Introduction

Offering a higher capacity than the Vortex range, see also the PRO 150 for programmability.

Pro 120 Mark 2 build on the success of the Pro controller. This itself was a development of (and includes all the features of) the original NCC series controllers. The circuits of these are so well proven and successful that no major design was possible, but the board has been re-laid using sub-miniature resistors to give room for more features.

The Pro includes a reverse polarity protection relay. The connections are all arranged at one end of the board for ease of access once the controller is boxed. The Pro-120 is a full feature Four Quadrant (acceleration and regenerative braking, forward and reverse) motor speed controller principally for 12v, 24v and 36v battery operation. Although it is similar in size to other industry standard 110 amp controllers, the power performance is considerably enhanced with no loss of reliability.

Some possible applications are:- invalid 'scooters', golf buggies, miniature railways, kiddiecars, floor cleaners, caravan shifters and vehicle loaders. The controller is adequate for all common golf buggies but for heavier and more demanding 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 240 amps. This feature is also popular with miniature railways where two engines are 'double headed'.

The Pro is 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 is the automatic ramp down and power off so the controller always stops smoothly and safely even if the ignition is turned off at full speed. Also of 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, high pedal lockout,ignition switch lockout and automatic reverse speed reduction.
