Operating Voltage: DC 5V - 36V; continuous current: 15A, enhance cooling conditions, the maximum current up to 30A; power: 400W. High Reliability, High Availability: It adopts double MOS parallel active output to show lower internal resistance,greater electric current and power. Besides it works at 15A,400W under common temperature which satisfies most devices usage and realizes the control of great power devices in a relaxed way. Supporting Multiple Signal Source Triggers: Can be connected microcontroller IO port, PLC interfaces, DC power, etc. 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. Material:PC+metal colour:Blue Package Contents: 20 x Trigger Switch 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 the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
