This thyristor DC power supply is a traditional DC power supply that can convert power frequency AC power into adjustable DC power. The main transformer adopts a rectifier specific transformer, and the front stage of the transformer is equipped with a medium voltage switch control cabinet to protect and control the rectifier equipment. The rectifier cabinet is used for voltage regulation and rectification through thyristors. The iron core of the transformer adopts directional electromagnetic steel sheets, which have high permeability and low hysteresis loss. The product has good performance, stable and reliable operation, and very complete functions, suitable for fields that require DC power supply such as electroplating, electrolysis, oxidation, water treatment, and electrochemistry.
1. The advanced main transformer ensures a complete machine efficiency of over 90% 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. 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.
6. High output stability: The system has a fast response speed (microsecond level) and strong adaptability to changes in grid power and load. The output accuracy can be better than ± 0.5%.
7. Equipped with a remote control operation cabinet, it protects the host and extends its service life, with a service life of over 10 years and safe and convenient operation.
