KBWT
PWM Drive – Chassis
The KBWT series Pulse-Width Modulated (PWM) controls, rated through 12 amps DC, are designed for high current applications. Several models are offered, which provide the user a choice of input voltage and output current. An important feature of this control is its active bridge circuitry, which limits inrush current during AC line startup and prevents control runaway due to a shorted output transistor. The KBWT also contains (I x t) motor overload protection and instantaneous short circuit protection.
Note: Horsepower ratings are for PWM rated motors. For SCR rated motors, the maximum horsepower rating is reduced by 20%.
