All-in-One Actuator - DC POWERED!

Exlar's newest product offering features the Tritex II DC powered unit, housing the servo drive, digital positioner and electric actuator all in one convenient package.  Tritex II actuators are the highest power density, smallest footprint servo drive devices on the market allowing you to incorporate a fully electronic solution in the space of your existing hydraulic or pneumatic cylinder.  You can also eliminate troublesome ball screw actuators or bulky servo gear reducers.  And the space previously consumed by panel mount servo drives and motion controllers is no longer needed.  Tritex II electric actuators may also reduce the size of your machine design while offering significant reliability improvement.

No Compromises on Power, Performance or Reliability

With forces to 870 lbs (4kN) continuous and 1,190 lbs peak (5kN), and speeds to 33 in/sec (800 mm/sec), the DC Tritex II linear actuators  offer POWER - a benefit you won't get with other integrated units.  The DC powered Tritex II actuators contain a 750 W servo amplifier and a very capable motion controller.  With standard features such as analog following for position, compound moves, move chaining and individual force/torque control for each move, the Tritex II Series is the ideal solution for most motion applications.

Tritex II DC electric actuators offer the ideal self-contained actuator solution for customers needing 12-48 VDC power input.  By incorporating power, actuation and control, the Tritex II DC actuators provide a complete motion solutions in one package.

Reduce Costs

Because the new DC powered Tritex II houses the servo drive, digital positioner, and actuator all in one convenient package, you eliminate the labor costs for mounting and wiring the panels. Cable costs are also significantly reduced by elminating the need for expensive, high-maintenance specialty servo cables. All that is required is an economical standard DC power cord, and standard communication cable for digital and analog I/O.

Also elminated are the issues associated with power signals and feedback signals traveling long distances from servo drive to servo motor. With the Tritex II, the servo drive and motor are always integrated in the same housing.

Linear Applications

Tritex II linear actuators employ Exlar's patented, inverted roller screw mechanism for converting rotary motion to highly robust and long-life linear motion. These characteristics enable the Tritex actuator to solve applications that previously required pneumatic or hydraulic cylinders. No additional mechanisms (such as acme or ball screws) are necessary to convert the actuator's rotary power into linear motion in order to move the load. In addition, the Tritex II software allows you to create a sequence which causes the actuator, when commanded, to move forward while pressing an object into position. You can establish a preprogrammed force which triggers an event (such as stopping or retracting to another position) or it can maintain tha force level until commanded otherwise. This sequence is ideal for assembly, test, fastening and pressing applications. The Tritex II linear actuator can be programmed to follow an analog command signal, making it ideal for controlling valves and dampers in process control applications.

Flexible Communications

Multiple feedback types, including absolute feedback, allow you to select the system that is best-suited for your application. Digital and analog I/O plus popular communication networks such as Modbus TCP, Ethernet/IP, PROFINET  and CANopen allow the Tritex II to become an integral part of your control architecture or machine control processes.
