Power Control (T) Principle
The power control regulates the displacement of the pump depending on the working pressure so that a
given drive power is not exceeded at constant drive speed, this function can prevent engine stall or
protect electric generator.

The precise control with a hyperbolic control characteristic, provides an optimum utilization of available
power.
