Installation Best Practise

Catching diode

If you have horns or relays fitted to your vehicle, you should fit a catching diode across each to prevent a damaging voltage spike, why? read on for the full story…. Coils, inductance and current Read More

Motor Noise Suppression

Electric motors are electrically noisy, the sparks commonly seen at the brushes are a source of radio frequency interference [RFI] that can interfer with both the host controller and other systems. Good motor noise suppression Read More

Fuses and Circuit Breakers

Choosing fuses and circuit breakers is a difficult subject…… Difficult because motor currents in most applications are very peaky. Difficult because the controller’s battery current is not the same as the motor current. Difficult because Read More

Good Wiring Practise

Our controllers get used in a wide variety of applications often switching large currents (several hundred amps perhaps) at around 20kHz. This makes the wiring used with them more critical, and this page tries to Read More
