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.
