2. Device description
2.1 Intended use
SDC107 is a driver designed for DC motors with power up to about 150 W.
The driver allows, to control the motor speed and direction of rotation, and the active reduction of the maximum
current drawn by the motor (6 A).
The motor speed can be set via an external signal 0-5 V or via the built-in potentiometer.
Motor operation control (work permit, change of direction of rotation, end inputs) is carried out using optoisolated
ENABLE / DIR / LIMIT N / LIMIT P inputs.
The current limit function (regulated by an external 0-5V signal or built-in potentiometer) allows limiting the
maximum current consumed by the motor and prevent it from overheating or damage.
Features:

Continuous current up to 6 A

Voltage supply 12..36 V

Maximum current limit to prevent motor overloading

Motor speed / current regulation by an external 0-5 V signal or built-in potentiometer

Quick configuration using 6 switches on the front panel of the driver

5 V output for supplying an external potentiometer

Optoisolated inputs for the activation (ENABLE), the direction (DIR) signals and the limit (LIM N, LIMP)

2 outputs (PNP) signaling error and achieving max. current

LED indicator for power, status and error

Overcurrent and short circuit protection of power amplifiers

Thermal protection

Compact housing adapted for mounting on a DIN rail
