Bardac SL Series, SLE Seriesv Data Sheet

powerSL Series

Analog DC drives - up to 75 hp

The powerSL Series of dc drives incorporate the well proven SLX, SL & SLE 3-phase basic OEM chassis drives into a compact package,
complete with high speed 3-phase power fuses, armature fuses (SLX & SL models only), control power fuses, contactor, and other
features.

Easy access to all internal power components and terminals is achieved in a compact, elegant package which, at 75hp is as small as a
81/2” x 11” note pad and is less than 101/2” deep!

powerSLX Series … 4-Q regenerative, reversing DC systems drive with field controller
powerSL Series … Non-reversing DC systems drive with field controller
powerSLE Series … Non-reversing DC OEM drive.
