EPH Elektronik 1Q speed controller with built-in current limiter

The 1Q speed controller from EPH Elektronik is a powerful and versatile resistor specifically designed for the precise control of DC motors. With a maximum armature current of 3 A and a nominal voltage of 24 V/DC, this device provides a reliable solution for applications requiring variable speed control. The speed controller is designed in a circuit board format, allowing for easy integration into existing systems. The current limit can be individually adjusted via a potentiometer, enabling adaptation to different load conditions. Additionally, the setpoint can be selected both internally and externally, increasing flexibility in application. The PWM MOSFET output stage ensures efficient performance with a high switching frequency of over 18 kHz, resulting in stable and precise control.

• Load-dependent transistor controller for precise speed control
• Adjustable current limit via potentiometer
• Setpoint selection internal/external via jumper
• Efficient PWM MOSFET output stage with high switching frequency.
