COD Mini 5A 90W PWM 5-28V DC-DC Motor Speed Controller Module Speed Regulator

Mini 5A 90W PWM 5-28V DC-DC Motor Speed Controller Module Adjustable Speed Regulator Control Governor Switch Specification: Working voltage: DC5V-28V Output current: 0-5A Output power: 90W (maximum) Static current: 7uA (standby state) PWM duty ratio: 1%-100% PWM frequency: 20KHz Product size: 30mmx26mmx14mm/1.18x1.02x0.55'' Product weight: 14g Paage size: 95mmx60mmx14mm/3.74x2.36x0.55'' Paing weight: 15g Warm Tips: 1. DC motor governor input is DC, not directly connected to AC, otherwise it will burn out. 2. DC positive and negative terminals do not reverse, otherwise the governor may be damaged. 3. The motor can be divided into positive and negative directions. When the direction of operation is not consistent with the expectation, the direction can be changed by adjusting the line order. 4. Adjusting the potentiometer knob can change the duty cycle of the governor and change the speed of the motor. Note: Please allow 1-3cm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
