RT-21 DC Powered Rotator Controller
The RT-21dc requires an external power supply capable of operating your rotator of choice. We recommend using:
Yaesu model 800, 1000, 2800 DC rotators - Single 13.8 to 24 VDC @ 4A
Alfa Spid, all models - Single 13.8 to 24 VDC @ 4A
TIC Ring - Single 24 VDC supply @ 4A, more if two motors
Higher voltage motors may be accomdated with a separate 13.8V supply < 500mA for the controller, and a higher voltage DC supply (up to 48VDC) for the motor.
AC motor units may be used if a separate source of appropriate AC voltage (isolated from ground) can be supplied.
The RT-21dc can be configured for all of the same position indicator variations as the standard controllers.
