Product introduction

· MOSFET is an electronic device with good switching characteristics, which is widely used in circuits that require electronic switching, such as switching power supplies and motor drives, and lighting dimming. Relay is very familiar with another module with switch properties, but due to the working principle of relay is generally by mechanical contact to reach the purpose of open and close, this is bound to lead to the switching time is very short, the condition of the relay will not work, the other contact switch in some cases the PaPa voice is more troubling thing.

· We designed a 4-way MOSFET switch to provide up to 4 sets of electronic switches for controlling different circuit modules. Affected by the working principle of MOSFET, the electronic block can only be used to control the DC circuit, such as DC LED screen, and is not suitable for the control of AC circuit. The MOSFET switch can be used to control 100V/33A dc circuit in the limit, but the minimum dc voltage to control is recommended to be not less than 9V.

· On the circuit connection, the controlled end of the connection is slightly more troublesome. To control the 12V LED lamp belt as an example, first in the positive(+) and negative (-) connected power supply;

· Then connect the positive pole of the LED lamp belt to the positive pole (+)of the module, and connect the negative pole of the LED lamp belt to switch 1(S1);

· If other LED strips need to be controlled, just connect the positive pole of the LED strip to the positive pole of the module (+), and connect the negative pole of the LED strip to switch 2 (S2), switch 3 (S3), and switch 4 (S4) in turn;

· The connection of the control end is much simpler, We only need to connect the corresponding control port with the sensor expansion board of the single chip microcomputer through the sensor connection line, and then we can control the 12V LED lamp belt through the single chip microcomputer, ln the experiment, we connected two LED strips.
