Autotransformer

Model GPR -  Autotransformer 
Electric Fire Pump Controller

  • An autotransformer is utilized to supply reduced voltage to the motor.
  • After a time delay, the autotransformer is shunted out and the motor is connected to full voltage by a closed transition switching sequence.
  • A multi-connection motor is not required. Only three conductors are required between the controller and the motor.

Model GPR + GPU - Autotransformer
Electric Fire Pump Controller with Automatic Transfer Switch 

  • Required if normal utility power is not reliable
  • Housed in a barriered compartment or in a separate enclosure attached to the fire pump controller
  • Listed and Approved for fire pump service
  • Equipped with a transfer switch TEST pushbutton
