PWM Speed, DC Drives, Chassis 4

The KBWD Series of DC Drives provide a low cost solution for pulse-width-modulated (PWM) control applications. Their compact size allows for direct replacement of SCR drives. Features include instantaneous short circuit and under voltage protection. A 5k ohm potentiometer is included.  This drive requires a Plug-in Horsepower Resistor®*, which eliminates the need for IR Comp and CL calibration. If signal isolation is required, please see models KBWS-22D and -25D. This drive also contains Auto Inhibit® which provides a smooth, safe start during rapid switching of the AC line.

Option: Combination Fuse kit (P/N 9849). (AC line and Armature fuse supplied separately.)
