Power Controller LR2 (Bosch Rexroth)

Possible Applications

This power controller is specifically deployed in industrial hydraulic systems utilizing Bosch Rexroth A4VSO and A4VBO axial piston pumps where constant power utilization is critical to protect the electric drive motor from overload. It is heavily relied upon in heavy-duty mobile machinery, large injection molding presses, and industrial metal-forming presses that demand high fluid flow at lower pressures and high pressure at reduced flow rates during their working cycles. By automatically adjusting displacement based on the hyperbolic pressure-flow product, the unit ensures optimal energy management and prevents prime mover stalling under peak load conditions. This makes it an essential control component for hydraulic power units operating continuous-duty cycles in the steel, manufacturing, and heavy construction equipment sectors.
