Features This driver uses original power MOS tube, can proceed PWM adjust output. It can drive up to 24V load, such as LED lamp strip, DC motor, mini pump, solenoid valve. PWM can be used to realize LED stepless dimming and motor stepless speed adjustment. The maximum output current is 5A, and it will need to install a heat sink when driving load more than 1A. There are total five pieces of driver boards in one set that you may use for many projects. Features:This driver uses original power MOS tube, can proceed PWM adjust output.
