Power Controller LR2N / LR3N (Bosch Rexroth)

Possible Applications

This power controller is primarily utilized in heavy-duty mobile machinery and industrial hydraulic systems where precise, load-dependent flow regulation is required. It is frequently integrated into hydrostatic transmissions for construction equipment like excavators and wheel loaders, where the pilot-pressure-related stroke control allows the operator to modulate pump displacement seamlessly based on joystick input. The inclusion of the hydraulic stroke limiter makes it particularly effective in industrial press applications or material handling systems where mechanical travel must be restricted to prevent structural damage during high-pressure cycles. By linking pump output directly to an external pilot signal, the device ensures responsive power management in closed-loop circuits that demand dynamic adjustment of hydraulic flow to match varying operational loads.
