Features: FET modules input and output is fully isolated. The signal triggers the end: the digital high-low.IO ports can be connected microcontroller PLC interfaces DC power supplies. The input voltage: 3V-20V; Current: 5mA or so. You can control the power output of the equipment motors light bulbs LED lights DC motors miniature pumps solenoid valves etc. Output controlled voltage: 5V-36V. Current: less than 5A if the current is more than 5A heat sank is needed------the maximum should be less than 20A. The original F5305S power FET can enter PWM control the motor speed the lamp brightness. Specifications: Overall Size : 46 x 25 x 18mm(L*W*H) Weight : 15g Package Content : 1 x Trigger Switch MOS Module aeProduct.getSubject()
