Description: Using original power MOS tube, can adjust PWM output Can let the drive up to 24 v load, such as LED lights belt, for dc motor, micro pump, solenoid for valve By PWM adjustable can realize stepless dimming LED, motor stepless speed regulation Product instructions: PWM signal for high level effectively When the PWM for high level (3.3 V to 3.3 V) : As the power supply voltage, between V + and V - working indicator, work load When the PWM is low level (0 V to 0.5 V) : V + and V - between 0, work lights out, don'for t work load and Material: Electrical Components Product Color: See Pictures Output load voltage :0-24V Drive up to 24V allows the load, such as LED lights, for DC motors, miniature pumps, solenoid valves Output load current: Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
