KBWM-120 电机控制
KBWM-120 9380 SCR CONTROL 1/50-1/3HP 115VAC 90VDC 1-WAY
KBWM-120
KBWM™ Vari-Drive™ adjustable speed SCR control for DC motors offers proven reliability in a rugged all-metal NEMA-1 enclosure. This unidirectional SCR drive utilizes the KBMM speed control module, which prevents motor failure due to demagnetization, and contains AC line and armature fusing and a barrier terminal connection block. The KB Plug-in Horsepower Resistor® automatically calibrates IR Comp and CL. 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. STANDARD FEATURES: Plug-in Horsepower Resistor®s. Allows a single model to be used on a wide range of motors AC line and armatures fusing. Rugged all-metal NEMA 1 enclosure. AC line ON/OFF switch with “power on” indicator lamp. Patented KBMM™ speed control module prevents demagnetization of PM motors. Proper size Plug-in Horsepower Resistor® and armature fuse must be installed for control to operate.
