1Q PWM

These drives are designed for 90, 130, 180 or 240 VDC non-regenerative motor applications. They are powered by a 50/60 Hz, 115 or 230 VAC line source and can control permanent magnet or field-wound motors. With continuous current capacities up to 15 amps, these drives can control motors within the 1/100 to 1.5 HP range. Enclosure styles include open-chassis and NEMA 1 steel. PWM drives will allow a motor to run cooler, prolong motor brush life, increase speed range, and are less susceptible to noise on the AC line than their SCR counterparts. 1Q drives are sometimes called “non-regenerative” or “uni-directional” drives. 1Q drives can only output voltage and current in one polarity and cannot oppose an overhauling load or decelerate a motor faster than the time it would take via a natural coast. Reversing must be done by swapping the motor wires via power contactors, switches, or relays and the load must come to a complete stop before reversing.
