Servo Power Units: Controls
Electro-Hydraulic Power Unit for use with Customer Cylinders
`
The Servo Power Unit (SPU) was developed as an alternative to the SMART Electro-Hydraulic Actuator (SHA) for those instances where the All-In-One SHA is not able to fit in the available space envelope. The SPU provides many SHA benefits including: precise position, speed and force control, compact size, and high force density. It connects to a customer-supplied cylinder through robust quick connect fittings. The SPU can be located close to the cylinder reducing footprint and reducing hose length.
Servo Power Unit Features:
