Brake control basics

YourDyno can control your brake. You can program RPM sweeps or steps or any RPM sequence, plus you can control brake RPM manually all through YourDyno.

Electrically, the brake control is done using an analog 0-5V signal, a PWM (Pulse Width Modulation) signal or a stepper motor DIR/STEP or STEP+/STEP- setup.

This can be used in the following ways:

  • Control an Eddy Current power supply
  • Drive an RC servo, typically for water brakes or hydraulic¬†brakes
  • Drive a servo motor using a motor controller
  • Drive a Stepper motor controller

Selecting analog signal or PWM

In order to select the analog output, move the jumpers to the position as shown below (marked AOut1 and AOut2). The other position is used for PWM and stepper motors.

    I am interested in using Your Dyno power supplies for a dyno project, and just had a couple of questions on the PWM input:
    Is a 3.3v PWM supply ok or does it need to be 5v?
    What frequency range should the PWM be within?

    Many thanks!

    Hi, I have a pair of the yourdyno power supplies and they look to have some sort of antenna sticking out from the side, does anyone know what the use of this is?
