The DC speed controller from EPH Elektronik is a highly developed 4Q speed regulator designed for use in various applications. With a maximum armature voltage of 24 V/DC and a current limit of up to 5 A, this passive component offers precise speed control. The setpoint for the speed can be adjusted either via a potentiometer (10 kΩ) or through an external voltage of 0 - 5 V/DC or 0 - 10 V/DC, with the selection made via a jumper. The armature voltage feedback is provided by an EMF with I x R compensation, ensuring improved regulation accuracy. This product is ideal for applications that require reliable and customizable speed control.

• Adjustable current limit via potentiometer
• Setting of the speed setpoint via external voltage input or potentiometer
• Jumper for selection of armature voltage (max. 12/24 V/DC)
• EMF feedback with I x R compensation for improved regulation accuracy.
