Application
RPU-90/180VDC
This unit provides all the features of an RT-21 controller, but applies them to large motor system up to two HP DC motors. Allows ring or top rotator to be added and used with an RT-21 for counter-rotation systems too. Rugged industrial rated design for robust performance along with all the fail-safe protections utilized with our standard controllers.
This unit requires an RT-21r for the controller, and 4 or 5 conductor of small guage cable to reach between the RT-21r and the RPU. A standard RT-21 also has the capability of interfacing with an RPU.
The RPU requires AC mains and is meant to be installed outdoors with it’s NEMA enclosure. For indoor mounting, or mounting in a larger equipment shelter, the enclosure may be deleted
RT-21 Rotator Controller, Standard
The RT-21 is a universal digital rotator controller that can be user configured for motor voltage and position feedback. Configuration is accomplished by a combination of PCB jumpers and software settings, no soldering or major disassembly is required. This flexibility allows the RT-21 to operate any commercial amateur rotator being built today, and virtually any rotator ever built. In addition, there are configuration settings that allow custom control for commercial and industrial systems.
Why upgrade your controller?
In addition to simply running your rotator or changing to meet your future rotators, the addition of an RT-21 will add modern functionality to your rotator:
- Adds USB and/or RS-232 control
- Adds high resolution digital display
- Adds Point & Shoot hands off operation
- In most cases, improves heading accuracy
- In most cases, adds PWM speed control and gradual start'/stop to your system eliminating tower and rotator stresses
The RT-21 manual contains separate pages detailing the setup, hookup and calibration of 14 of the most common rotators in use. Additional resources are available from Green Heron in the form of applications notes, that detail less common or custom requirements. In addition, we have developed experience and have documentation on many older rotators and custom requirements.
Common Rotators Supported and Documented in the Manual:
- Hy-gain HAM series, T2X and HDR-300
- Create RC5 series
- Yaesu All models
- Orion 2800 and 2300 models
