Motor-control system provides feedback for positioning
The DCH403-10 is a low-voltage electronic motor-control system with a single-phase a.c. line source. The DCH403-10 combines a custom “regen-capable” switching power supply with a low-voltage drive to allow control over low-voltage motors without the negative effects of currents spikes or the large BUS voltage associated with typical 115/230 VAC controls. The unit’s built-in circuitry diverts regenerative current to a dump resistor, allowing for quicker braking than most PWM drives, says the company. The DCH Series is ideal for applications including solar-powered devices, mobile equipment and actuator control. — American Control Electronics, South Beloit, Ill.
