CURTIS 1213 CONTROLLER
CURTIS 1213
The Curtis 1213 controller was used on our model 48 sweepers 
until 1997. The controller is an adjustable controller that has true 
regenerative braking that also provides complete downhill decel-
eration and speed control. This controller required no forward and 
reverse contactor due to its full bridge design.
FEATURES
  - Full bridge power MOSFET design.
  - Silent operation
  - Current limiting in both drive and brake modes
  - Potentiometer adjustable acceleration, deceleration and reverse speeds
  - Power failure default braking
  - Anti rollback/roll forward circuitry
  - Terminal overload protection
SPECIFICATIONS
  Operation Voltage:  24 Volts
  Controller capacity:  200 amps
  Outputs
