4Q SCR

These drives are designed for 90 or 180 VDC regenerative motor applications. They are powered by a 50/60 Hz, 115 or 230 VAC line source and can control either permanent magnet or field-wound motors. With continuous current capacities up to 25 amps, these drives can control motors within the 1/20 to 5 HP range. Enclosure styles include open-chassis and NEMA 4X steel. 4Q stands for 4-Quandrant, sometimes called “regenerative” or “bi-directional”. These drives can output voltage and current in two polarities. 4Q drives can oppose an overhauling load, decelerate a motor faster than the time it takes via a natural coast, and can reverse on-the-fly without the use of power contactors, relays, or switches.
