This is our range of motor speed controllers that can be used in a wide variety of applications powered by brushed DC electric motors. To choose the appropriate controller for your application, you need to know the current and voltage requirements, and decide whether you need reversing capability. We’ve put together some flow charts on this page which can help you make your selection.
Porter: Single direction, 12V – 48V, 100A.
The Porter range are tough, low cost, single direction controllers that are particularly suitable for karts, golf caddies, electric bikes, equipment handling, and industrial applications.

DNO: Reversing, 12V – 36V, 100A.
A popular mid-sized controller with built-in reversing suitable for use in 12V to 36V applications. DNOs are commonly used in small / mid-sized locos, electric vehicles and industrial applications.
£91.50–£109.50 More Info
Pro-120: Reversing, 24V, 120A.
The Pro-120 is a mid-size controller, suitable for currents up to 120A. Commonly used in mid-sized locos and golf buggies. It has been replaced by the newer PRO-150 digital controller, but is still available for some niche applications.
£172.50–£178.50 More Info
Pro-150: Reversing, 24v – 48v, 150A, programmable.
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.
£151.50–£193.50 More Info
4QD range: Reversing, 24V – 60V, 300A
The 4QD-200 and 4QD-300 are heavy duty 4 quadrant motor speed controllers for currents up to 300A. They are suitable for larger locos, battery powered vehicles, electric boats, and any application that needs a really powerful controller. They are fully electronic with no internal relays, and have many fail-safes built in for reliable long time use.
