• The KBWT-16 is 115 VAC • Designed to operate PWM and SCR rated Permanent Magnet motors ranging from 1/50 HP to 3/4 HP. • Advantages of PWM (Pulse width modulated): - Produces an almost pure DC current to the motor (form factor 1.05) - Provide excellent dynamic response to load variation - Significantly lowers audible motor noise and provides longer brush life - Produces less motor heating allowing a smaller, less costly motor to be used for most applications - Higher output voltage, which provides increased output speed - Pulse-by-pulse current sensing provides short circuit protection and prevents control damage due to shorted motors • A unique feature of the KBWT Series is its active bridge, which provides a substantial reduction in AC line surge current each time the control is turned on. This allows the control to be turned on or off rapidly without damage to critical components. • Contains a built-in safety circuit that will shut down the control if the main power transistor short circuits. This prevents high-speed runaway, a potential problem with competitors’ controls. • Utilizes heat-spreader construction. It provides an enhanced thermal path that eliminates overtemperature cycles which cause premature failure of the power transistors. • KBWT (I x t) motor burnout protection, which will shut the control down if the motor is overloaded for a predetermined time, and the Potentiometer Safety Circuit™ (optional), which prevents the control from starting when the AC line is applied unless the speed potentiometer is reset to zero. • Diagnostic LED’s for “Power On” and “Overload (OL)” indication are also provided • Contains quick disconnect terminals as standard. • Contains auto inhibit which provides a smooth, safe start during rapid switching of the AC line • A potentiometer (5K), isolated analog input signal (0-5 VDC), or PWM microprocessor output can be used to vary the output of the control • Dimensions: 5.00" x 7.00" x 2.00" • Line fuse: Required • Resistor and armature fuse: Required
