Power Controller LR3 (Bosch Rexroth)

Possible Applications

This power controller is primarily utilized in heavy-duty hydraulic systems where dynamic adjustment of pump displacement is required to match fluctuating load demands during operation. It is frequently integrated into large-scale industrial shredders, tunnel boring machines, and forestry harvesters where the ability to remotely modulate power characteristics prevents engine stalling under peak torque conditions. By allowing operators to shift the control threshold via external pilot pressure, the unit optimizes energy efficiency in closed-loop or open-loop circuits that experience frequent, rapid changes in hydraulic resistance. This makes it an essential component for mobile machinery and stationary test rigs that demand precise, real-time control over hydraulic power output to maintain system stability and prevent mechanical overload.
