Problems solved by technology
[0002] The original high-voltage power supply components are discrete, the voltage stabilization performance is poor, the voltage output value cannot be adjusted, and the power supply itself lacks effective protection
At present, the three-phase voltage of the company's power grid has reached 418VAC, making the original high-voltage output power of 3.5 ~ 4KV reach 4.5KV, which makes the amplifier work unstable, and the excessive voltage is harmful to the power supply lacking effective protection and the entire circuit of the amplifier. Fatal, especially when working under chronic overload
