DCH403-10 Low Voltage Motor Control

DCH403-10 Low Voltage Motor Control

DCH Series

Many customers prefer to use low voltage motors for a variety of reasons. The issue many run into however is that they don’t have a battery source available to run these motors. The solution is to use a power supply, but that isn’t always ideal. Power supplies can be a limiting factor in an application, such as they cannot accommodate regenerative current in a braking or reversing application.

The DCH403-10 addresses this issue by combining an AC to DC switching power supply with a regenerative PWM drive, creating an all-in-one solution to applications requiring control of 12 to 48 VDC motors when only 115 or 230 VAC power is available. The true lower output voltage will run your motor cooler and prolong brush life. The DCH403-10 is capable of speed or torque control, as well as cycling and positioning control when used with limit switches or resistive feedback devices. However, the microprocessor allows the drive to be programmed for custom applications or routines to meet OEMs requirements and the built-in isolation keeps PLC interfacing safe and simple.

The DCH403-10 is perfect for those needing a wide range of low voltage motor control with quick braking or on-the-fly reversing when only AC line power is available.
