EPH Elektronik 4Q-Drehzahlregler mit Strombegrenzung

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 the setpoint for the speed to be specified either via a potentiometer (10 kΩ) or through external voltages in the range of 0 to 5 V/DC or 0 to 10 V/DC, with the selection made via a jumper. The armature voltage can also be set via a jumper to a maximum of 12 or 24 V/DC. Another important feature is the adjustable current limitation, which is controlled by a potentiometer. Additionally, the controller offers armature voltage feedback with EMF and I x R compensation, ensuring improved control accuracy and stability. With these features, the 4Q speed controller is a reliable solution for applications that require precise speed regulation.

• Adjustable armature voltage (12/24 V/DC) via jumper
• Setpoint for speed via potentiometer or external voltage
• Adjustable current limitation for added protection
• Armature voltage feedback with EMF and I x R compensation.
