2.6 Power stage
All inputs and outputs are located on the power stage.
The power stage is protected from surge currents and short circuit by four current sensors and a current detector.
The outputs for controlling the brewer motor are non-locking.
This means that these outputs are normally protected. The outputs could only sustain damage in the case of a direct open-circuit.
All other outputs are short circuit-resistant. The outputs are not damaged even in the event of open circuit
