Description
Specification: Item type: PWM motor speed switch. Material: Electronic Components – Operating Voltage: DC 4.5V-28V Output current: 0-5A. Output power: 90 W (maximum). Standby current: 7uA (standby mode). PWM duty cycle: 1% -100%. PWM frequency: 20 kHz. Weight: approx. 16 g. Package contents: 1 x motor speed controller switch. Notes: The input of the DC motor controller is DC and it is not directly connected to the AC current (e.g. B. 220 V AC), otherwise it will burn out. ! ! Do not swap the positive and negative connections of the DC supply, otherwise the controller may be damaged. The motor can be positive or negative. If the running direction does not match the expectation, the direction can be changed by adjusting the line order. By adjusting the potentiometer button, the speed controller working cycle is changed and the engine speed changes.
