Electrical Control Enclosure The REXA XPAC Series 3 electrical control enclosure serves as the actuator’s intelligent positioner, housing the power supplies, motor drivers, and a dedicated microprocessor that work together to deliver precise, reliable control. Built within a rugged 316 stainless steel enclosure, the system integrates the display and keypad, motor driver, CPU, power board, and power input assembly, which includes a fuse holder, noise filter, and surge suppressor. For simplified installation and maintenance, all power and I/O connections are routed into the control enclosure and terminate on a DIN rail located at the bottom of the enclosure, providing an organized and accessible wiring interface. Construction 316 stainless steel material. NEMA 4X / IP66 rated User Interface Simple, user friendly push-button calibration. Electrical Components Key components include the motor driver, CPU board, power board and an interconnect board with warning, alarm and position indication relays.  Connection point for customer supplied main electrical power Control System I/O Control signal digital communication and alarm relay out.  Interconnect Cables REXA supplied color-coded cables connect the electrical control enclosure to the actuator assembly.

Electraulic™ Power Module The REXA Electraulic™ Power Module is REXA’s unique motor and pump system. The system is a positive pressure, closed-loop hydraulic type that minimizes oil volume and eliminates the need for filtration or routine fluid maintenance. Unlike traditional hydraulic power unit type systems, there is no fluid conditioning requirement for a REXA actuator. There are no filters, desiccant, or fluid change intervals necessary to maintain fluid cleanliness. The pump system is inherently clean and maintains a constant positive pressure to prevent ingress of moisture, dirt, or any other potential fluid contaminants.  This unique approach creates a hybrid-like actuator operation that combines the best characteristics of electric and hydraulic systems. The Electraulic™ Power Module delivers the power and performance capability of hydraulics with the discrete motor operation of an electric type system, only consuming electricity when a position change is needed. During normal position control operation, the electrical control enclosure converts the incoming control signal into a target position. The system compares the target to the current position measured from a feedback sensor mounted on the actuator cylinder. If the deviation of the target position and current position exceed the user-programmed deadband, the system initiates actuator motion. The motor drives a bidirectional gear pump to generate the hydraulic output necessary to move the actuator. Oil (5w50 motor oil) travels from the pump through a series of pilot operated check valves, called the Flow Matching Valves (FMV). Each FMV manages oil transfer out of one side of the cylinder and into the other. Pressure builds and drives the actuator to the target position. Once the target position is reached, the motor and pump stop, each FMV close hydraulically locking the actuator cylinder in place. The motor only turns on again if the signal deviation exceeds the deadband, and a position change is required. The motor and pump are not required to hold a steady position. This reduces unnecessary power consumption resulting in considerable operational savings.  Click below to learn how this unique motor and pump system is applied to our XPAC Series 3 Linear Actuators, Rotary Actuators, and Damper Drives!  X3 Linear Actuators XPAC Series 3 Linear Actuators utilize a double acting hydraulic cylinder driven by one or more Electraulic™ Power Modules.
