KBWD-16 KB Electronics 6 Amp PWM 115VAC Chassis Drive 8607

KBWD-16 Pulse Width Modulated DC motor speed control (wisper drive) provides excellent dynamic response to load variations. The efficient PWM waveform produces an almost pure DC current to the motor, which has several advantages over a conventional SCR control. The PWM significantly lowers audible motor noise and provides longer brush life. It also produces less motor heating, which allows a smaller, less costly motor to be used for most applications.
Another advantage of PWM is higher output voltage, which provides increased output speed. In addition, pulse?by?pulse current sensing provides short circuit protection and prevents control damage due to shorted motors.

Standard features include: Instantaneous short circuit protection, under voltage protection and KB’s Plug-in Horsepower Resistor®, which eliminates the need to calibrate IR Comp and CL. A potentiometer (5k), isolated analog signal (0-5VDC) or PWM microprocessor output can be used as an input signal.
