Feature: 1. The potentiometer knob can change the duty cycle of the governor output to change the motor speed. 2. Widely used in industries such as CNC machine tools, papermaking and printing, textile printing and dyeing, and optical cable and cable equipment. 3. A modular DC motor speed controller that integrates power supply, control and drive circuits 4. The three‑dimensional structure is adopted, the control circuit adopts micro‑power components, and the photocoupler is used to realize the isolation and conversion of current and voltage. 5. The speed governor is small in size and light in weight, and can be used alone or directly installed on a DC motor to form an integrated DC speed regulating motor Specification: Item Type: DC Motor Speed ControllerTechnical Parameter: Model: CCM96SK Potentiometer: Resistance Value B100K; Opening: Approx. 8mm / 0.3in Input Voltage: DC10-60V The Output Voltage is The Input Voltage: Approx 0-100% Control Power: 12V x 10A=120W, 24V x 10A=240W Rated Current: 10A Maximum Current: 20A Speed Adjustment Range: 5%-100% PWM Frequency: 25kHz. Package List: 1 x Speed Controller Note: Precautions and instructions for use:1. The input of the DC motor speed controller is direct current, and cannot be directly connected to alternating current (such as household 220V alternating current), otherwise it will burn out2 The positive and negative poles of the DC power supply cannot be reversed, otherwise the governor will be damaged.3. The motor can be positive or negative, when the running direction is inconsistent with the expectation. The direction can be changed by adjusting the line sequence.4 Adjust the potentiometer knob to change the duty cycle of the governor output, thereby changing the motor speed.
