Precautions for use:
1. The power supply has a rated power of 350W and can be equipped with a 300W*2 power amplifier board. Due to the customer's operating temperature and environmental reasons, the heating of the power supply varies during use. If you feel the temperature is too high, you can use the built-in 12V fan to assist in heat dissipation.
2. This power supply comes with over-power and output short-circuit protection, but since it will impact the power supply itself, try to prevent short-circuit and overload during use.
3. This switching power supply has a semi-enclosed design, and the power supply does not have other casings. Please put it into the case in actual use. Pay attention to safety and be careful of electric shock!
Using pure aluminum heat sink and shell, there are 3 M3 fixing holes in the middle of the bottom, which can be fixed on the chassis or on a larger radiator.
There are also 2 M3 fixing holes on each of the two sides, and a radiator can also be installed or fixed on the side.
Output terminal: +24V and G are connected to the power supply terminal of the power amplifier board, +12V and G can be connected to a small fan to assist heat dissipation or speaker protection circuit.
Input terminals: L and N are respectively connected to the live wire and the neutral wire of the plug. FG can be connected to the shell or the ground wire.
