All Models have built in field weakener for extended speed range.
SL 5-145KW
Single direction 2 quadrant DC Motor controller. Models from 5kw to 50kw and 145kw include a rate controllable fully regenerative stopping facility. This star feature is unique to Sprint Electric and completely eliminates costly and wasteful dynamic braking resistors or even the requirement for a 4 quadrant drive. Available in two slimline package sizes 5-50kw and 65-145kw, the SL is dimensionally identical to the SLX.
SLX 5-145KW
4 quadrant regenerative drive providing motoring and braking in both directions of rotation. Like the single phase 4Q 3600XRi model, this controller is highly efficient in repetitive braking, reversing or overhauling applications. Both the SL and SLX present many system features including built in high accuracy isolated armature voltage feedback and automatic field weakening for extended speed range. Extremely compact footprint ensures easy integration within new machine designs.
