DCH401-5-LFB Positioning Control

DCH401-5-LFB Low Voltage Motor Control

The DCH401-5-LFB is a modified version of our DCH401-5 for linear positioning applications. It is designed to take in a resistive feedback signal that the drive uses to compare with a commanded position signal, which the drive will then act on to move the motor forward or reverse until the two signals match. The control can be accurate to within 1/1000th of commanded position.

The DCH series combines an AC to DC switching power supply with a regenerative PWM drive, creating an all in one solution to applications requiring control of 12 or 24 VDC motors when only 115 or 230 VAC power is available. The microprocessor design allows the drive to be programmed for custom applications or routines to meet an OEMs needs. With an isolated front end, this series is compatible with a 0-5 or 0-10 VDC analog from any PLC.

Potentiometer Kit 202-0101 is included with a purchase of the DCH401-5-LFB

  • Microprocessor Based: Allows custom programming for OEMs
  • All-in-One Package: Combines a custom regen-capable switching power supply with low voltage drive
  • True Low Voltage Output: Allows control over low voltage motors without the negative effects of current spikes or a large BUS voltage associated with typical 115/230 VAC SCR and PWM controls
  • 4Q Reversing: Regenerative / 4-Quadrant drives have the ability to perform quick and contactorless braking and/or reversing-on-the-fly
  • Isolated Logic: Allows floating or grounded 0 - 5 or 0 - 10 VDC signals
  • Stopping Modes: Forward and reverse inhibits can be set for N.O. or N.C. to brake to a stop. Can be used for rapid starting and stopping
  • Diagnostic LEDs: Power, Current Limit
  • Positioning Control: Standard drive has been modified to allow for positioning control with a resistor feedback.
