- #1 Features are programmable. The Pro-150 will funcion as a normal controller straight out of the box without any programming.
- #3 standard feature on 24v controllers only - 12v subject to minimum quantity
- #4 Standard -RB includes regen, Use -NB for no regen braking version.
- #5 fin is also mounting
- #6 M4, M6, M8 = 4, 6 or 8mm studs. 6.3 and 9.5 = push-on blades.
- #8 48v versions are generally not popular so many are only available subject to minimum order quantities.
- #9 Standard Porter has an absolute maximum of 55v. A fully charged 48v battery can exceed this if overcharged during regen braking. This voltage can be increased to special order. See separate page on 48v controllers.
- #10 Pot fault protection can be fitted to the Uni, but is dependant on pot value so it is not normally activated.
There is also an archive of obsolete models, for reference only. This can be useful if you wish to identify a controller to be replaced.
- 24v and 36v
- All controllers are available for 24v operation. Some will work on 36v as well while other controllers have a 36v version available.
- 12v operation
- A separate page lists controllers available for 12v operation.
- 48v operation
- A separate page lists controllers available for 48v operation.
