programmable motor controller

Pro-150: Reversing, 24v – 48v, 150A, programmable.

£145.00£185.00

The Pro-150 is a mid-size digital controller, suitable for currents up to 150A. It is commonly used in mid-sized locos, golf buggies, and industrial applications requiring more customisation of performance characteristics. The Pro-150 is electrically and mechanically interchangeable with the Pro-120 in most applications.

Product Description

Probably the most user-friendly programmable motor controller available. Programming is easy, using the (optional) low-cost combined display / programmer unit.

Key features are:

  • Will function as a standard controller without any programming.
  • Optional display shows system state and battery voltage.
  • Programmable control over many features including:
    • Acceleration.
    • Deceleration.
    • Maximum power.
    • Dead band.
    • Sounder [for reversing and audible problem alert]
  • Pot learning feature allows:
    • Single ended, or joystick mode [wig-wag].
    • Fine tuning of input values
  • 10 memories for different configurations.
  • Continuous diagnostics monitors controller and system.
  • Thermal overload protection.
  • Under and over voltage protection.
  • Reverse polarity protection.
  • Integral box and heatsink [suitable for most applications].
  • Built-in heavy duty reversing relays.
  • 16V to 48V without adjustment.
  • Peak current 150A. 1 minute current 80A. Continuous current 60A [heatsink dependant].
  • Parking brake driver for vehicle applications.
  • Regenerative braking.
  • Input 1k ohm to 15k ohm potentiometer, direct voltage control, or PWM control by Pi or Arduino etc.

We can program it for you

We’re happy to discuss your exact requirements and configure the Pro-150 before shipping. Please note that the default settings have the reverse beeper switched on, this is a good idea for golf buggies and other electric vehicles but may not be so good for that scale loco with a sound card.

Display / programmer

The programmer and the display are the same unit – in two halves so they can be separated once initial programming is done. The display, once the controller has been installed, is used to show battery state and to give a visible indication of any fault detected.

Simple wiring

All the essential inputs are on one 6-way connector. More advanced features are on a separate connector. See the support tab for the instruction manual, wiring diagrams, and instructions for double heading..

Safe

The on-board computer monitors the controller and much of the external system. Should a fault be detected, the computer will shut down the controller and give an indication of the fault audibly and on the (optional) external display.

Versatile

Special programming becomes possible so that 4QD may introduce special features such as

  • Radio control
  • Serial control from PC
  • Positional servo control
  • Time profiled current limiting
  • Log of system faults detected

if these (or other) features interest you, please email us.

Support

The manual provides full instructions on setting up and operating the controller. The manual is available in two formats, one for reading on screen, and one for printing as a double-sided booklet:

Troubleshooting

For troubleshooting common to all controllers click here.

Slow / fast switch

With version 2.3, the operation of the slow / fast switch as described in the manual has been changed. If pins A and B are connected [or the – button on the programmer held for 3 seconds] at start-up, the controller will then start up in personality 9. This allows better control over the behaviour of the controller in an easily selectable alternative mode. Once pins A and B are disconnected, the controller will revert to it’s previously set personality on the next power-up.

Power down mode

Some customers have requested that the power down mode be disabled. We have a software version 2.4. that keeps the controller awake. Please contact us if you require this version.

Joystick [wig-wag] mode

For those customers who want to operate the Pro-150 from a joystick with a centre off position this article has instructions on how to program it.

Pot fault

There is a very thin track on the PCB adjacent to the 3 and 6 way connectors, it’s circled in red in the picture below.. This is actually a scratch through link that allows modifications to the input circuit but under certain short circuit conditions we have seen this act as a 3rd fuse track and blow. If this does happen to your controller then just bridge the pads with some 1A fuse wire.

Software versions

Version Changes
2.2 Version to support change from Atmega 16 to 164A
2.3 Fast / slow switch operation changed
2.4 Power down mode disabled, on request only
2.5 Change to inprove production yield at 50V

We reserve the right to change the software without notice as we find ways to improve the product. If you have a requirement for a specific version then please contact us.
