PWM DC Motor Speed Controller Speed Adjustable Switch LED Control Dimming Module DC 4.5V-35V 5A 20khz Max 90W

説明

1.Working voltage: DC4.5V-35V

2.Output current: 0-5A

3.Output power: 90W (maximum)

4.PWM duty cycle: 1% -100%

5.PWM frequency: 20kHz

Working principle of product module:

By changing the duty cycle size through PWM, the output voltage size can be changed, thereby changing the motor speed.

特記事項：

The input of the DC motor speed controller is DC power, and it cannot be directly connected to AC power (such as 220V AC power for household use), otherwise it will burn out!!!

·Do not reverse the positive and negative terminals of the DC power supply, otherwise the governor may be damaged.

·The motor can operate without distinguishing between positive and negative directions. When the direction of operation does not match the expected direction, the direction can be changed by adjusting the wire sequence.

·Adjusting the potentiometer knob can change the output duty cycle of the governor and the motor speed.

Attention to LED dimming wiring:

When the module is used for dimming LED lights, a current limiting resistor needs to be connected in series to prevent excessive current in the LED lights.
