4-Quadrant Power Supply and Dynamometer Controller

4-Quadrant Power Supply and Dynamometer Controller

The 4-Quadrant Power Supply and Dynamometer Controller can perform a wide variety of functions, like DC voltage or current source, AC source, battery charger, solar panel emulator, constant speed or torque brake and wind or hydraulic turbine emulator.

The module is powered from a single phase outlet and acts as a green device, feeding back mechanical or electrical energy it receives to the power network with unity power factor. All inputs and outputs are protected against improper connections and overvoltage/overcurrent conditions.

For the operation of the 4-Quadrant Power Supply and Dynamometer Controller different sets of functions can be enabled by purchasing the respective firmware. Although these firmware functions can be bought individually, we have bundled the most popular ones in several packages. Each of these packages is described below.
