AC Input

American Control Electronics offers drives designed to run on 115 or 230 VAC line power to control 90, 130, 180, or 240 VDC permanent magnet or field-wound motors. Our product offering includes drives that can operate in a 1Q mode (uni-directional), 1Q bi-directional mode (reversing via armature contacts), and 4Q bi-directional mode (regenerative). Enclosure styles range from open-chassis to NEMA 1 steel, NEMA 4X steel, and NEMA 4X plastic. With features such as isolation, torque control, tach feedback, and even custom programming on microprocessor based models, you're sure to find something that will satisfy your application needs.

1Q SCR

1Q SCR

These drives are designed for 90 or 180 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 25 amps, these drives can control motors within the 1/20 HP to 5 HP range. Enclosure styles range from open-chassis, NEMA 1 steel, NEMA 4X steel, and NEMA 4X plastic. 1Q stands for 1-Quadrant and refers to the way a drive controls a motor. 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.

1Q PWM

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.

4Q SCR

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.

4Q PWM

4Q PWM

These drives are designed for 90, 130, 180 or 240 VDC regenerative motor applications. They are powered by a 50/60 Hz, 115 or 230 VAC line source and can control permanent magnet motors. With continuous current capacities up to 7 amps, these drives can control motors within the 1/20 to 1 1/2 HP range. 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. 4Q stands for 4-Quandrant, sometimes called “regenerative” or “bi-directional”.
