High Reliability and High Availability: Adopt two imported parallel MOS active outputs, lower resistance, electric current is larger, high power, 15A, 400W at temperature, matches most equipment on the market. Perfect Support PWM: You can access PWM signal, signal frequency 0-20KHZ is perfectly supported. Wide Applications: You can control the output of electrical equipment, motors, incandescent lamps, LED lights, DC motors, micro pumps, solenoid valves, etc., can input PWM, control motor speed, lamp brightness, etc. High Reliability, High Availability: It adopts dual MOS parallel active output to show lower internal resistance, higher electric current and power. Note: difference or physical color difference, please don't mind! Type: high power field effect transistor trigger switch drive module, PWM controller, electronic switch control board. Color: Blue Material: PCB Package Contents: 30 * MOS drive module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in a little different from the real thing. The measurement allowed error is +/- 1-3cm.
