EM-295C is a one direction DC motor speed controller. The controller uses PWM principle and works high efficiency. The PWM frequency mode can be set to high or low freq .
This device has designed for speed control use. The rpm is regulated against supply voltage changes and the RxI compensation improves rpm stability at low rpm. The current limit limits the torque of motor or shutdown the motor Device has also few auxliary I/O. The output can be used for fault indication or brake control. The inputs can be used as a end limits, stop, brake or freewheel control input.
