3. Product features:
① Because of the use of fully sealed oil-soaked cooling structure, not only greatly improve the working conditions of semiconductor devices, but also directly put the rectifier on the edge of the plating cylinder is not eroded by corrosive gas, greatly improve the reliability of the machine.
② Rectifying transformer adopts high magnetic conductivity cold rolled silicon steel sheet, designed into three-phase five-column, six-phase or 12-phase unbalanced
Reactor output structure, than the general three-phase three-column rectifier transformer energy saving about 10%.
③ It has the function of automatic voltage stabilizing and current limiting, current stabilizing and voltage limiting. The output voltage and current can be continuously adjusted.
1) Voltage stabilizing and current limiting function: when the rectifier is working in this state, if the load changes, the voltage will be stable,
The current varies with the load. When the current reaches or will exceed the rated current, it is automatically in the current limiting state, that is, the maximum current does not exceed the rated current, and the voltage will drop.
2) Current stabilizing and voltage limiting function: when the rectifier is working in this state, if the load changes, the current will be stable and the voltage will change with the load. When the voltage reaches or will exceed the rated voltage, it is automatically in the voltage limit state, that is, the maximum voltage does not exceed the rated voltage, and the current drops.
④ It has high and reliable over-current and short-circuit protection function.
When the load current exceeds 50% of the rated value, the rectifier will automatically block the output pulse, the operation time is 10ms and maintain the equipment to normal, and restart.
⑤ It has the function of phase loss protection
When the three-phase power line is missing phase, the rectifier will automatically block the output pulse, the operation time is 10ms and maintain the three-phase power voltage is normal, and restart.
⑥ This product is equipped with a remote control box or with a number of equipment for the use of computer centralized monitoring system (need to be specified in the order).
The main transformer adopts two vacuum dip paint or hot dip paint, drying.
The three-phase integrated trigger control board has multiple protective measures, is a novel anti-in

terference strong integrated double pulse trigger circuit, advanced performance, good output waveform, reliable operation, convenient debugging.
⑨ with soft start function, prevent large current impact, prolong the life of the equipment, ensure the quality of the coating or oxide film.
Attensives adopt computerized standardized design, reasonable structure of the whole machine, sealing and anti-corrosion design of the control line, small volume, light weight, convenient loading and unloading, easy installation and maintenance, and plastic spray treatment of the box body, anticorrosive and beautiful.
