Motor Controller

For continuous protection, monitoring and control, you need a true powerhouse system. We carry the F-5, F-3 and F-1 Series Tornado Motor Controller with Display. The Motor Controller with Display provides intelligent and advanced motor protection. This system uses surface-mount technology for maintenance-free reliability and longevity. Quick-release electrical connectors allow for problem-free connection and easy replacement of all system components.

The Motor Controller with display monitors all three phases of incoming and outgoing voltage current for balance. It has two discrete and two analog inputs for over and under set points. The system is also designed to shut down the motor during adverse conditions, and automatically restarts the motor when the conditions become safe. With this valuable assistance, you can rest assured that your system is under control at all times. 

Optional Units include the Display (F-5 and F-3) Units, which can be either used as permanently installed equipment, or plugged in as desired to check and/or set system operating parameters; the Backspin Relay and Probe (F-5); the Data Logger (F-5); and the Amper (F-3).
