KNACRO Quad FET MOS electronic switch control panel Pulse trigger switch DC contro Frequent high-frequency circuit to achieve fast off;-off process does not produce noise; there is no spark, no electromagnetic interference; longer life than conventional electromagnetic relay life. Signal trigger terminal: digital high-low. You can access the microcontroller IO port, PLC interfaces, DC power supply. Input signal voltage: 3V ~ 20V; Current: 5ma about. Effect of tube modules, input and output are completely isolated. Output voltage charged: 5V ~ 36V. Current: less than 5A 5A need to add heat sink, the maximum should not exceed 20A. F5305S with original power FET can enter PWM, motor speed control, lamp brightness. You can control the output of power equipment: motors, light bulbs, LED lights, DC motors, micro-pumps, solenoid valves and so on.
