Motor noise suppression

We strongly recommend fitting motor noise suppression components to each motor in your system to protect the controller. See this quick explanation of what EMC is and why it matters. We have interference suppression packs  and a page of advice on how to fit them, and other steps to take to reduce RFI.

Remember to order multicore cable for control wiring


Our Pro-360 takes the advanced features and high voltage rating of the Pro-160 and couples them to a new power stage capable of some seriously high currents. It uses the heavy duty bus bars and heatsink structure of our proven 4QD-300 to handle currents up to 360+A making this a really high power programmable controller, we also have enhanced air cooled and liquid cooled heatsinks available.

The new Pro series  has been designed from the ground up to give a wide range of features. Full control over the motor current in both drive and regen modes, and inputs for radio control, temperature and speed sensors, dead mans handles, and limit switches etc. It has a display to show voltage, current, and temperature that can be taken off and mounted conveniently. The built-in keypad* means it’s easy to adjust between steady or very dynamic operation.

The standard version is ideally suited for motors up to around 10kW, and the high voltage version up to 15kW. The standard maximum voltage is a nominal 48V, but we also have high voltage variants that can go to 84V. We have recently introduced HC and HCV versions that have up-rated capacitors to allow sustained operation at the higher currents typically found in electric boats.

The key features are:

  • 2 line LCD display – this can be mounted remotely or on the controller and gives full information on your installation e.g.
    • Battery voltage
    • Motor and battery current [you’ll be surprised how different they can be!]
    • Controller temperature, [motor and battery temperature – needs optional sensors] .
    • Throttle position.
  • Built in radio control input with battery eliminator circuit [BEC].
  • Easily adjustable control over many features including:
    • Acceleration and deceleration.
    • Maximum speed.
    • Maximum drive current.
    • Regenerative braking current [variable “on the fly” in 2.3.4].
    • Dynamic braking in joystick mode – pull back to brake [in 2.3.3].
    • Low voltage alert and “limp home mode” to protect expensive lithium batteries.
  • Deadmans handle input for seperate guard activation.
  • A single switch to choose between any 2 profiles e.g. RC and hand control, or fast and slow. Ideal for training new drivers.
  • 15 profiles for storing different configurations, 1st 9 pre-programmed for the most common applications.
  • Top speed limiting [requires external sensor].
  • Overheat warning and cut-out , also overheat warning for 2 motors with extra sensors.
  • 12V to 84V without adjustment, * depends on version.
  • Peak current 360A.
  • Input learning feature allows:
    • Single ended or joystick [wig-wag] operation.
    • Fine tuning of pot or RC stick positions.
    • Voltage control.
  • Safety contactor driver.
  • Parking brake driver for vehicle applications.
  • Push button mode.
  • Other inputs:
    • Emergency stop.
    • 2 x limit switches.
    • 2 x  thermistor inputs for monitoring battery and motor temperature.
    • Speed sensor.
  • Software updates via uSD card.
  • Based on a specialised Infineon microprocessor with deadtime control to prevent shoot through mosfet failures.


The Pro-360 can be built in a variety of specifications to give exactly what you want;

  • Voltage – the standard specification is 12V – 48V, but by fitting uprated mosfets and capacitors the upper voltage can be raised to 84V.
  • Display / keypad – the standard Pro-360 has a 2 line backlit LCD display under the cover. The display can be detached and mounted remotely, either on its own or on the adaptor board that has its own keypad.
  • Heatsink – the standard heatsink is suitable for many applications, for higher loads we have enhanced air cooled heatsinks and water cooled versions.

Simple to fit

The Pro-360 has all the essential control inputs on one 6-way connector. Here’s a video showing how to install one.

The full instruction manual is on the support tab.


The microprocessor monitors the controller and parts of the external system. Should a fault be detected, the processor will shut down the controller and display an indication of the fault. If a safety contactor is incorporated, the power stage can be disconnected to protect against run away failures.


With a range of voltage, display, and cooling options the Pro-360 is ideal for use in electric boats, larger model locos, golf buggies, and industrial applications. It is highly configurable, but provides the basic control functions right out of the box. In terms of our existing products it has a feature set that is much greater than the 4QD-300 but with similar current handling, and a much increased voltage range. The Pro-360 can be used as an alternative to many Curtis controllers, and has the advantage of not requiring a separate programmer.

Linear actuator software

We have now developed software that allows the Pro-360 to respond to a feedback voltage from a position sensor, the aim being to create a really powerful servo mechanism, see video on this page. Contact us for details.

The manual provides full instructions on setting up and operating the controller.

    1. As well as the fuse tracks F1 and F2, there is this small, zero ohm resistor [R112] that can blow if the control wiring is short circuited. It can be repaired by bridging with a small wire link.
  1. To use only radio control of the Pro-360 it is still necessary to connect the ignition switch terminals of the main control input.
  2. The Pro-360 has sophisticated on board diagnostics and will display a fault code whenever it is not happy with something. A list of all the fault codes is here.


Display adaptor board

The Pro-360 display can be removed from its normal position and mounted anywhere convenient for the operator. The display adaptor board allows the display to be mounted together with a remote keypad to make adjustments easy without having to dive under the bonnet. The adaptor board is supplied with a 1m LCD display lead, and a 1m keypad lead. It is possible to have longer leads, but we recommend using screened cable for any display leads greater than 2m.

Pro-160 display adaptor board and seperate display

If you just want to mount the LCD remotely [and don’t need the adaptor board] you will just need the LCD display lead.

Temperature sensor.

These temperature sensors are specially selected and calibrated to work with our Pro-160 / 360 controllers. One or two of these sensors can be plugged directly into the thermistor port on the control board, and the software set to show the temperatures on the display. The Pro-160 / 360 can also provide warnings at user selectable temperatures.

[Needs software at version 2.3 or above]

Speed sensor

This speed sensor works with our Pro-160 and Pro-360 digital controllers. It can be plugged into the speed port on the control board, and the software can then be set to show and limit the RPM on the display. The sensor detects a North magnetic field which can be from the 1cm disc magnet included, or any other suitable magnet capable of giving a field of 7mT. Supplied with a 1.5m screened lead and 5 way IDC connector.
