Welcome to our shop! This trigger switch board is made of high-quality material, ensuring durability and a long service life. It has a maximum drive current of 8A and a standby current of less than 0.11-1mA. With low standby power consumption and high output power, it is perfect for various applications such as self-locking electronic switches, development boards, motors, relays, solenoid valves, and more. The board works as a trigger switch, meaning that once triggered, the output terminal will output the power supply voltage and won't trigger the output terminal without voltage output again. The power supply voltage for this board is DC 9-24V (H9-24V version) and it features a driver IC, the N-channel MOSFET AOD4184, which can handle a maximum drive current of 8A. The continuous output current is 8A (9V-15V) and 6A (15V-24V) for the H9-24V version. The size of the board is approximately 36 * 17.5 * 14mm / 1.4 * 0.7 * 0.6in and it weighs about 7g / 0.2oz. Please note that when using this board with inductive load, it is recommended to connect appropriate freewheeling diodes in parallel to avoid damaging the switching elements of the circuit. 100% Satisfaction: Our customers are our top priority.
