Attention:
- It is a bare board with high-voltage circuit. Professional knowledge is highly recommended.
- Circuit and component grinding and epoxy resin potting treatment. Schematic diagram, PCB and technical support are not provided.
- Air cooling fan is needed for long-term high-power use. The power supply features over-temperature, over-current and short-circuit protections. It will be locked when over-current and short-circuit protections are triggered. You must disconnect your AC power supply, wait for the voltage of main filter capacitor to drop to 0V, and then restart.
- This power supply is a true LLC resonant power supply, and the resonant circuit features high-frequency sine wave. It is not an ordinary square wave switching power supply, which is very suitable for power amplifiers, with excellent performance.
- Each power supply has been tested before delivery. The board is constantly upgraded and revised, and the component circuit may be changed. Please refer to the actual items. Thank you for your understanding!
Note:
- Please leave a message about the main output voltage you need. Different voltage capacitors have different component parameters. Please refer to the actual product.
- Since the switching power supply only regulates the main voltage, the current of independent and auxiliary outputs must be less than the current of main voltage output. For example, when the current of main voltage is 10mA, the auxiliary and independent cannot withstand a load of more than 10mA.
- Please choose the main voltage type you want when purchasing. Voltage capacitors and component parameters are slightly different. Pictures are for reference only. Please refer to the material items.
- Other items in the pictures are not included, for demonstration purposes only.
Wiring:
It is tested with resistance wire and a load. The input voltage is AC 218V and the power is 3411W.
