• LED electrodeless dimming
• Chemical plating and speed control
• Scientific research and testing
• Student and hobby projects

Key Notes:

1. The maximum current output is fixed at 20A. The actual current is determined by the connected load. Devices requiring less than 20A current can be safely used, but those requiring more than 20A should not be connected.
2. For inductive loads such as motors and fans, ensure the starting current does not exceed the power supply's maximum capacity. Exceeding this may damage the power supply. For such cases, choose a power supply with higher current capacity or use a soft-start protection circuit to absorb impact currents.
