Pro-150 Digital Motor Controller
Keep this manual safe after installation in case a fault develops in your
system and you need to refer to the manual's fault finding information. The
latest version of this manual is always available from 4QD's www site.

1 Introduction

The PRO 150 (PROgrammable 150 amp controller)
is the first of a new range of 4QD motor controllers
to benefit from digital technology.
The PRO 150 is a digital, four-quadrant motor
controller for battery operation of permanent magnet
DC motors. 4 Quadrant means that it controls speed
and direction, drive and braking.
The standard controller is suitable for 24v to 36v
batteries (14v through 42v operation). The 48v
version is suitable for battery voltages between 16V
and 48V.
The controller will not operate from 12v.
The Pro-150 can deliver a motor current of up to
150A for short periods and up to 60A continuously.

The Pro-150 is digital: it uses computer technology.
This gives two advantages:
1 controllers with the identical programming will
behave identically and reproducibly.
2 The controller is 'intelligent' and, at power-up
checks itself and its environment for faults: if it finds
a fault, it will not operate but will display a fault
code.
If all is correct, it then starts to operate and the
display (if fitted) will read the battery voltage.
When a display is not fitted, a sounder is present
which will give a coded series of pulses to indicate
the fault found. This can be particularly useful in, for
instance, diagnosing a problem over a telephone
The Pro-150 is probably the easiest controller to
program that exists.
