Load Control Systems for DYNertia3 ('closed loop' brake dyno control)
With the addition of one of our load controllers you can completely replace outdated dyno control systems or design your own DIY custom dyno equipment. Suitable for engine or chassis style dyno, large or small.
Our load controllers work in conjunction with the DYNertia3 system, so it is important you also view the DYNertia3 page for all relevant information and the many included features.
The load control system communicates with special DYNertia3 software and implements full 'closed loop' control. Its tunable PID control ensures the target RPM/speed is quickly and accurately met and held. This allows the dyno to perform automated 'ramp' tests, 'step' tests, user designed 'profiles' or even just be manually controlled from within the software or via a potentiometer (knob, lever or pedal).
There are two types of units we offer and they differ in the way their output signal can be used -
EC- The Eddy current controller is wired into the workshops mains supply and can provide up to 192VDC and 25A to directly control an Eddy current brake (retarder). Most 12/24V retarders can be configured to run from 192V (coils in series) and this is how most existing Eddy current dyno's are already configured.
PC- The PWM controller provides a variable pulse (PWM) signal that can be used to drive retarders that are configured for lower voltage operation. The output must be connected to the retarder via a 'driver' to handle the high current, this is usually a device such as a transistor or MOSFET.
Brake (absorber) type dynos apply a load (e.g. Eddy current brake) against the engine and the torque applied is measured on your ‘load cell’. This is typically an 'S-beam' type (requires an amplifier) but can be the signal from a pressure sensor (hydraulic load cell) or a potentiometer (mechanical load cell).
Even a precision rotational sensor is included with the kit to be used with your dyno's ‘trigger wheel’, typically a toothed iron gear (or precision drilled plate).
