It is built on a rugged aluminum chassis and utilizesthe KBMM speed control. The drive contains Direct-Fed CL that helps protect the SCR power bridge against shorts dueto commutator arcing and prevents motor demagnetization. The unit contains a 42 Amp power bridge and both armature andcontrol fusing, which enhance reliability. They include an armature or tach feedback, supplied Armature fuse and trimpots forMIN, MAX, IR Comp, CL, Linear ACCEL, DECEL, and a 5k ohm speed potentiometer. This drive also contains Auto Inhibit whichprovides a smooth, safe start during rapid switching of the AC line.
