DC motor controller 39 series

brushlesscompactpotentiometer

Compact Low Voltage Brushless DC Controls STANDARD FEATURES • Input Voltage Range: 12-14 VDC (model 3908) or 24-35 VDC (model 3909). • Control Functions: include dynamic braking, direction, and enable. • Speed Adjustment: can be controlled by an external potentiometer (included), the onboard MAX speed trim potentiometer, or a 0-5 VDC analog input signal. • User-Adjustable Pots: for speed settings, torque limit, acceleration time. • 12 PPR (pulse/revolution) tach output provides indication of motor speed. • Inherent closed loop system maintains a 2% maximum change in motor speed from 0-100% of rated load when operated at rated speed. • Smart Reverse™ circuit prevents plug reversing if the user accidentally or intentionally changes the direction signal without bringing the motor to a stop first.
