• The KBWS-22D is 115-208/230 VAC • Designed to operate PWM and SCR rated Permanent Magnet motors ranging from 1/50 HP to 2 HP. • The dual voltage models contain a jumper to select motor voltage and special circuitry which automatically accepts AC line input voltages of 115 or 208/230 Volts AC without having to make a jumper selection. • They operate at a switching frequency greater than 16 kHz to provide high motor efficiency and quiet operation. • Standard features include: - Built-in isolation for all inputs. - Signal voltage - Main Speed Potentiometer - Inhibit Circuit and +5VDC Power Supply • Contains pulse-by-pulse current sensing, which provides short circuit protection and prevents control damage due to commutator arcing. • Controls contain an AC line inrush current limiter (ICL) which reduces the AC line surge current during startup. • The controls are ruggedly constructed and contain a remote 5K speed pot. • Requires a plug-in Horsepower resistor to operate • Also contains auto inhibit which provides a smooth, safe start during rapid switching of the AC line • Dimensions: 4.30'' x 3.60'' x 3.20'' • Line fuse: Required • Resistor and armature fuse: Required
