To achieve quick turn-on and off the circuit, an unlimited number of switching; Conducting and cutting process does not produce noise, no sparks, no electromagnetic interference; Longer service time; The dual-MOS parallel drive, lower resistance, more current, strong power; at room temperature, operating current of up to 15A, power up to 400W, to meet the most use of the equipment; A method for controlling the motor, lights, LED, DCmotors, micro-pumps, solenoid valves, etc. Features: Wide voltage input (5-36V), most devices can be used, very convenient. The interface is clear and simple, powerful, easy to understand, meet almost all your needs. The emergency-stop function ("STOP" button), with reverse polarity protections, reverse polarity will not burn the product. Increase the sleep mode, if this mode is enabled, without any operation within 5 minutes, then automatically turn off the monitor, any button wakeup. After the module is powered down, all parameter settings are not lost. Specifications: Operating voltage: 5-36V. Output capacity: DC5V-36V 15A, 400W (Enhance heat dissipation conditions, the maximum current up to 30A.)
