EPH Elektronik 4Q speed controller with current limitation

The 4Q speed controller with current limitation from EPH Elektronik is a passive component designed for precise control of the speed of DC motors. It allows for flexible adjustment of the desired speed setpoint via a potentiometer or external voltages from 0 to 10 V/DC, enabling easy integration into various applications. The armature voltage can be set to 12 or 24 V/DC as needed, enhancing the versatility of the device. Additionally, the controller features an adjustable current limitation that ensures the protection of the motor and connected components. The feedback of the armature voltage is achieved through an EMF with I x R compensation, ensuring precise control and stability during operation. With its compact dimensions, the controller is ideal for applications where space is limited and provides a reliable solution for motor control in various industrial and technical environments.

• Adjustable armature voltage (12/24 V/DC) selectable via jumper
• Desired speed setpoint adjustable via potentiometer or external voltage
• Integrated current limitation to prevent overloads
• EMF feedback with I x R compensation for precise control.
