4Q PWM

These drives are designed for 12, 24, 36 or 48 VDC regenerative motor applications. They can control permanent magnet motors with peak current capacities up to 1000 amps. 4Q stands for 4-Quadrant, sometimes called regenerative” or “reversing”. These drives can output voltage and current in two polarities and 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.
