KBWD – Pulse Width Modulated Whisper Drive

Products Description
The KBWD pulse width modulated (PWM) DC motor speed control provides excellent dynamic response to load variations. The efficient PWM waveform produces an almost pure DC current to the motor (form factor < 1.05) 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.
