DC Speed Controllers
Anaheim Automation offers a low-cost DC Speed Controller to compliment its DC Motor product line. The printed circuit board style Brush DC Speed Controller offers external potentiometer speed control, external voltage speed control, 2-quadrant operation, and an open-loop velocity mode. These DC Speed Controllers are compatible with motors up to 10A and 50V. Screw-Type terminal blocks provide for quick and easy installation.
The MBDC050 series is a DC Brush Speed Controller designed to drive DC Brush Motors at currents of up to 10A (peak) at an input voltage range of up to 50 VDC (model dependent). An external 10k potentiometer or an external DC Power Supply can be used to vary the speed of the motor. This controller features protection from over-current (cycle by cycle) and over-voltage. The fault protection is set for a cycle-by-cycle motor turn-off. Cycle-by-cycle over current limiting is done by monitoring the motor peak current and upon an over current of 10A for the MBDC050-050101 and 3A for the MBDC050-024031 the fault LED turns on to notify the user of this error. When over-current occurs the motor phases are immediately turned off and held off for the remainder of the internal PWM oscillation. A red LED light illuminates to notify the user when an error occurs.
