Xpac Electraulics Actuators & Drives
Brand: Rexa, Inc
The REXA Xpac Electraulic™ Actuator is a superior positioning device well suited for critical control applications.
The product is designed to control severe process conditions in harsh environments and provide high reliability.
Electraulic™ Actuators and Drives provide the final control element capabilities to match the most sophisticated instrumentation and distributed control systems.
The Xpac is comprised of the mechanical subassembly and the electrical subassembly.
The mechanical subassembly consists of a double acting hydraulic cylinder, position feedback sensor and an Electraulic™ Power Module.
The power module is a unique, self-contained, sealed hydraulic pumping system which manages oil pressure and flow to and from the cylinder.
The electrical subassembly consists of the power supplies, motor drivers and a dedicated microprocessor.
The combination of these mechanical, hydraulic and electronic technologies gives the Xpac its state of the art capability.
