behind auto scrubbers and the 200 burnishers. The 1228 is a
fully programmable controller and comes in 24 and 36 volt ver-
sions. This controller has regenerative breaking which provides
downhill and deceleration speed control.

- Infinitely variable forward, reverse, drive and brake control
- Silent high frequency operation
- Fully programmable
- High pedal disable
- Drive motor limiting in both drive and braking modes
- Battery under voltage protection
- Power failure default breaking
- Thermal protection limits controller current
