4QD - DC Motor Control

Welcome to 4QD

We manufacture a range of electronic speed controllers for DC battery powered electric motors that are tough, reliable, and easy to use.
Our range covers 30 to 300 Amps, 12 to 60 Volts, and can be used in a wide variety of applications, including golf buggies, model locomotives, karts and other electric vehicles, boats, equipment handling, special effects, and industrial processes.
Our controllers are manufactured exclusively in the UK.

We are keen to support customers in developing their applications and would like to hear from you if you have unique applications or ideas for new products.
