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.
 

RPU-90/180VDC Description:
The RPU consists of an industrial PWM motor controller, interface board, relays, fuses and connector block all mounted on a 9" x 11" x 3/16" aluminum plate.  As standard, the plate is mounted in a fiberglass NEMA enclosure with watertight fittings for cable entry.  The enclosure may be painted for longer lasting outdoor protection.

We recommend suitable limit switches directly in series with the motor leads.  However, the RPU does provide a low current limit switch arrangement to lockout the primary input relay as an alternative or additional protection.
 
RPU-28VDC Features:
  • PWM speed control for 90VDC motors up to 1 HP, 180VDC motors up to 2 HP 
  • Fail-Safe design (similar to all RT-21) prevent run-away even with component/system failures
  • Provisions for primary relay lockout using limit switches
  • Aluminum plate/heat sink can be wall mounted or mounted inside equipment shelter
  • Standard enclosure includes industrial water-tight cable feedthoughs
  • Can be mounted anywhere between the controller and the rotator 
  • Small guage 6 conductor cable is all that is required between controller and RPU  (CAT 5) 
  • Requires RT-21r or standard RT-21 for controller, all features of the controller are maintained
