High Reliability & High Availability: Adopt two parallel MOS active output, lower resistance, electric current is bigger, strong power, 15A, 400W at room temperature, meet with most equipments on the market. Perfect Support Pwm: You can access the PWM signal, the signal frequency 0-20KHZ perfect support. Widely Applications: You can control the output of power equipment, motors, light bulbs, LED lights, DC motors, micro-pumps, solenoid valves, etc., can input PWM, control motor speed, lamp brightness and so on. High Reliability, High Availability: It adopts double MOS parallel active output to show lower internal resistance,greater electric current and power. Please note:the physical slightly color difference or difference,please do not mind, thank you!
