5V-35V PWM DC Motor Speed Controller Module
₦ 2,000Description:
5V-35V PWM DC Motor Speed Controller Module is a Mini Style DC Motor Speed Regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM). This allows controlling the speed of a motor with fully adjustable 0%-100%.The motor speed controller can easily provide a continuous current of 3A to your DC motor or other DC load.
Features:
- Mini DC 3-35V 5A PWM Motor Speed Controller. Wide voltage DC motor speed controller, PWM duty cycle: 1% -100%.
- Mini Style DC Motor Speed Regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM).
- Default disconnection of short circuit point, suitable for 5-35V input.
- Manually connect the short circuit point according your needs, suitable for low power 3-15v input.
- By screwing the potentiometer, you can turn off power supply output. High voltage and high current resettable fuse, overcurrent automatic disconnection, power off for cooling for a few seconds fuses automatic recovery.
Specifications:
- Operating voltage: DC4.5V-35V
- Output current: 0-5A
- Output power: 90W (max)
- Quiescent current: 7uA (standby)
- PWM duty cycle: 1% -100%
- PWM frequency: 20khz
- Size: 30mm x 26mm x 14mm (Without Handle)
Precautions:
- DC motor governor input is DC, can not directly connected to the AC (for example: home 220V AC), otherwise it will burn!
- DC power supply positive and negative terminals do not reverse, otherwise the governor may be damaged.
- The motor can be positive or negative, when the direction of operation and expectations do not match, you can adjust the line order to change the direction.
- Adjust the potentiometer knob to change the governor output duty cycle, the motor speed changes.
