Regulating 4.5V to 35V, the PN35 5A 90W PWM DC Motor Speed Controller manages motor RPM and LED brightness. A 20kHz frequency prevents audible humming during operation. Under high humidity, the exposed PCB requires an enclosure to prevent short circuits.
Key Features
- Wide Voltage Range: Supports 4.5V to 35V DC input. Compatible with lithium packs and 24V industrial power supplies.
- 20kHz PWM Frequency: Cycles power at ultrasonic speeds. Stops motor whine and visible LED flickering during dimming.
- Self-Recovery Fuse: Trips during overcurrent events. Resets automatically after the component cools to prevent hardware failure.
- Ultra-low Quiescent Current: Draws 7uA during standby. Stops battery drain in portable robotics during long idle periods.
Frequently Asked Questions
Can I use this PWM controller for LED dimming?
Yes. The 1-100% duty cycle provides linear brightness control for DC LED strips and panels.
How to connect PN35 motor speed controller?
Attach the power source to the input terminals and the load to the motor terminals. Reversed polarity destroys the controller immediately.
