KBWM-120 (9380) DC Drives, NEMA-1, 115 Vac, Thru 0.33 HP, 0-90 V
KBWM-120 (9380) DC Drives, NEMA-1, 115 Vac, Thru 0.33 HP, 0-90 VDC
The KBWM™ Vari-Drive™ adjustable speed SCR
control for DC motors offers proven reliability in a rugged
all-metal NEMA-1 enclosure. The Vari-Drives are equipped with
the ultimate KBMM™ speed control module. They are specifically
designed for fractional horsepower permanent magnet (PM)
DC motors. Two models are offered. The KBWM-120 is
designed for 115 VAC input and is rated 1/100 - 1/3Hp at 90
VDC. For motors rated 1/50 - 3/4 Hp at 180 VDC use Model
KBWM-240.
KB’s exclusive Plug-in Horsepower Resistor®*
automatically presets the drive’s IR Comp and CL circuits for
safe operation on various motors. Although factory
calibrated, internal trimpots for Min, Max, IR, CL, Accel and
Decel can be used to fine-tune the KBWM™ for specific
applications. Connections to the control are via a barrier
terminal block. By changing the orientation of the front cover,
the wiring can be brought in either from the bottom or the top
of the control.
Motor failure due to demagnetization is eliminated by the
patented ultra-fast Direct-Fed™ current limit circuit. The
controls contain AC line and armature* fusing, which provide
protection against catastrophic failure. Auto-Inhibit®, a KB
exclusive, allows the drive to be turned on and off rapidly using
the AC line without damage to the control and/or motor. The
internal CL LED is a diagnostic indicator that lights when the
motor is overloaded.
A conveniently located front panel lighted rocker switch
controls AC line input power to the drive.
*Plug-in Horsepower Resistor® and armature fuse supplied separately
Dimensions: 3.70" x 6.80" x 3.00"
