AC Variable Speed Drive Trainer, Extended


DAC #429 AC Drives Trainer, Extended

Developed in cooperation with TII Technical Education Systems, this portable, benchtop training system enhances the functionality and usefulness of our #429 AC Drives Trainer by allowing for additional wiring opportunities and fault troubleshooting. As with the basic #429 trainer, it allows for self-paced training in basic AC motors, basic AC drives, drive programming, and control applications.

All I/O and control wiring capabilities of the Allen-Bradley, Model 1305 drive can be accessed using banana jack connections on the front panel face. Additionally, eight fault switches are provided on the back of the electrical enclosure allowing for drive, motor and control wiring troubleshooting. A digital tachometer is provided.

Using the standard DAC #940 Control Module structure, this product can be easily integrated with the DAC #905 Electromechanical Bench, and products relating to PLCs, sensors and piloting switches.

Whether used as a stand-alone training device or in combination with other DAC automation-related training products, this device will help make training in this fundamental technology more informative and productive.
