Finished drive board
12V 24V universal SG3525 driver board, this driver uses TIP41, TIP42 to make totem, so that the driver board drives the tube more powerful, but the problem of insufficient heart drive. The drive board is protected by overcurrent and the over-current (short-circuit) protection. The default frequency of the drive board is 11-22KHZ. Changing the resistance of R14 can be changed to other frequency ranges. The buzzer will beep when it is protected. . . . Call.
The pre-stage overcurrent protection is sampled by the shunt in the negative pole of the battery input or a section of the negative input line.
1: RP1 is the overcurrent regulation point. Optional current protection (VIN cannot be left floating during test drive, must be connected to GND to be negatively charged) VIM floating drive board will enter protection
2: RP2 is SG3525 frequency adjustment, adjustable range is 11-22KHZ
3: Test the driver board after the stage overcurrent (short circuit protection) Short-circuit the C and E of the driver board. Look at the board and it will enter the protection: if it enters the protection, if the optocoupler is activated, the driver board will be connected. Protected, the latter sampling does not provide sampling circuit, the parents play.
The drive can be inserted into the board with a single curved needle, or it can be fixed with screws. There are four holes of φ3.5 at the four corners.
