Product Introduction
Our company uses high-quality materials and rigorous manufacturing processes for the controllable silicon electrophoretic rectifier. The main transformer adopts a three core five column double star structure, and the transformer iron core is made of imported high-quality silicon steel sheets with grain oriented cutting and strict control of joints. The transformer coil is wound with excellent oxygen free copper wire and adopts two impregnation processes. The primary side control rectifier uses imported high-voltage controllable silicon components, the secondary side uses domestically produced high-quality rectifying components, and the secondary side control uses imported controllable silicon components. Improved efficiency by 15% compared to traditional thyristor rectifiers.
Product advantages
1. The advanced main transformer ensures a complete machine efficiency of over 81% and has good energy-saving effects.
2. Adopting cabinet structure, electrostatic spraying protection, beautiful appearance, and sturdy structure.
3. The selection of components has a large margin, strong load-bearing capacity, and long service life.
4. The circuit is highly integrated, with strong anti-interference ability and low failure rate.
5. By using high-performance LC filters, the harmonic components of the rectified output voltage are effectively suppressed, meeting the requirement of low ripple output in the electrophoretic painting production process.
6. It has a soft start function that can be adjusted from 0 to 999 seconds, and is equipped with a three-level timing function. The current and voltage of each stage can be set separately, and the stable or stable current mode can be selected according to process requirements.
7. Due to the use of a highly reliable control system on the main control board, it has the characteristics of strong anti-interference ability, high control accuracy, good stability, and reliable operation.
8. It has functions such as voltage regulation (constant voltage), current regulation (constant current), soft start, phase loss protection, overvoltage/undervoltage protection, overcurrent protection, overheating protection, etc., ensuring safety issues.
