Electro-Hydraulic Actuator (EDU)
The EDU is an advanced electro-hydraulic system that integrates a hydraulic pump, cylinder, and electric motor. This high power-density system allows for independent adjustment of load and velocity in both directions. Designed for efficiency, the EDU is ideal for power-on-demand applications in mobile environments, requiring only an electrical power connection to operate.
Benefits
