Safe operation and protection Built with a 30A fuse and a reversepolarity protection function to safeguard the power supply and connected loads from incorrect wiring or overcurrent events. Digital display and readout power design paired with a digital display for clear, realtime monitoring of PWM control. 3digit LED readout displays 000 to 100, representing 0% to 100% PWM duty cycle. Control design Potentiometer with an integrated switch function for convenient, singlelocation control and quick on/off operation. Display details and visibility The 3digit LED display shows values in the 000–100 range; for example, 055 equals a 55% PWM duty cycle. Large 0.56 inch digits enhance visibility, allowing easy reading in challenging lighting or busy environments. Key attributes Function: PWM duty cycle control with safe operation features. Compatibility: designed to integrate with typical PWMdriven power circuits and loads. Size and display: 0.56 inch , 3digit LED readout for quick interpretation. Performance: reliable protection, straightforward control, and clear, accurate dutycycle indication. Applications and use scenarios DC motor speed control in robotics or RC projects: adjust duty cycle with the potentiometer and read the exact percentage on the display. LED dimming or heater regulation in lab or bench setups: use PWM to regulate average power with a clear readout for precise tuning. Power supply testing and debugging: monitor PWM percentage while adjusting settings to verify behavior and performance. This description preserves the original product's features (30A fuse, reverse protection, digital display, potentiometer with switch, PWM readout 000–100, 0.56 inch digits) while presenting them in a clear, customerfocused format with practical usage scenarios.
