ITEM NAME:HW-687 PWM DC Motor Speed Controller Module DC4.5V-28V Adjustable Regulator Product Description Description: HW-687 5A PWM DC Motor Speed Controller Module DC 4.5V-28V Adjustable Speed Regulator LED Switch Governor Dimmer Specifications: Operating Voltage: DC 4.5V-28V Output Current: 0-5A Output Power: 90W (Maximum) Quiescent Current: 7ÃŽ ¼A (Standby) PWM Duty Cycle: 1% -100% PWM Frequency: 20kHz Size: 30 X 26 X 14mm/1.18 X 1.02 X 0.55" Cautions: 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. Notes: 1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! 2. Please allow 1-3mm measuring deviation due to manual measurement. Included: 1 X PWM DC Motor Speed Controller.PWM Duty Cycle: 1% -100%. PWM Frequency: 20kHz. 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.
