With phase loss protection function

When the three-phase power line is out of phase, the rectifier will automatically shut down the output pulse, the operation time is 10ms and keep to the three-phase power supply voltage is normal, and restart.

(2) With automatic voltage regulation and current limiting, stable current and voltage limiting function, the output voltage and current can be continuously adjustable.

⑤ The product is equipped with a remote control box or a computer centralized monitoring system for multiple equipment (to be explained when ordering).

1) Voltage regulation and current limiting function: when the rectifier is working in this state, if the load changes, the voltage is not disorderly, and the current changes 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, the voltage drops.

⑨ Can choose 4-20MA,0-5V,0-10V analog control interface or digital control mode with RS-485 communication interface.

Product details

This product is widely used in electroplating, oxidation, electrolysis, rare earth smelting and electrophoretic paint, chemical equipment anti-corrosion anode protection, battery charging, DC motor speed control and other places requiring DC power supply.

3. Product Features:

(1) The rectifier transformer adopts high permeability cold-rolled silicon steel sheet, designed into three-phase five-column type, six or twelve phase without balance reactor output structure, than the general three-phase three-column rectifier transformer energy saving about 10%.

With high reliability over current, short circuit protection function. When the voltage reaches or will exceed the rated voltage, it is automatically in the voltage limiting state, that is, the maximum voltage does not exceed the rated voltage, and the current drops.

⑦ Three phase integrated trigger control board with multiple protection measures, is a novel anti-interference strong integrated double pulse trigger circuit, function to improve the predecessor, good output waveform, reliable operation, convenient debugging.

When the load current exceeds 50% of the rated value, the rectifier will automatically shut down the output pulse, operate for 10ms and hold until the equipment is normal, and restart.

The main transformer adopts two vacuum dipping paint or hot dipping paint, drying.

2) Current stabilization and voltage limiting function: when the rectifier is working in this state, if the load changes, the current is not disorderly, and the voltage changes with the load.

With soft start function, to prevent the impact of large current, prolong the life of the equipment, to ensure the quality of the coating or oxide film.
