Here is our range of PWM motor speed controllers that can be used in a wide variety of applications using DC brushed permanent magnet electric motors. The Porter and DNO controllers are analogue models that provide the main functions at a cost-effective price. The Pro series are all digital controllers with multiple user programmable profiles that allow a much greater degree of control over motor performance. [caption id="attachment_11671" align="alignnone" width="600"] Our controllers[/caption] To choose the appropriate controller for your application you need to know the operating voltage and current requirements, and also decide whether you need reversing capability. The DNO and Pro-150 models use relays to provide reversing at lower cost, the Pro-160 and Pro-360 models are full H-bridge controllers without relays to give long term reliability and overload tolerance. If you need a display of voltage, current, and temperature then have a look at the Pro-160 or Pro-360. We've put together some flow charts on this page which can help you make your selection. Please feel free to give us a call, we're always happy to talk about how we can help get your motor control project up and running.
