Power supply rectification technology:

Plating power supply frequency is a direct current equipment of changing industry frequency alternating voltage into different voltage, frequency and waveform. In the thyristor rectifier main application of “rectification” technology, while in the high frequency switching mode power supply applying both “rectification” technology and “inverter” technology.

Plating Power supply mainly consisted of main circuit and control circuit.

Power supply definition:

Changing different voltage, frequency and waveform.
Power supply components: Main circuit and control circuit.
Power Frequency: 50Hz/60Hz.
Application: zinc plating, anodizing, chrome plating, copper plating, and other nonferrous metals plating.
Alternatives to silicon-controlled rectifier and oil dip power supply.

200A Power supply

200A Power supply

Power supply main circuit includes main transformer, power rectifier components and some other testing, protection devices. Power supply main transformer function is to reducing AC current/voltage to the plating technical process required voltage value. Thyristor rectifier uses frequency (50Hz/60Hz) transformer, while high-frequency switching power supplies using high frequency (10 ~ 50kHz) transformer. Detection devices include voltage meter, current transformers. Protection device is mainly used for power rectification components over-current protection. The control circuit includes a thyristor or IGBT, trigger control circuit, power soft-start circuit, over-current, over-voltage protection circuit, power phase protection circuit.
