China 12V 8000A High Power High Current Anodizing Rectifier, Find details about China Electroplating Rectifier, Electroplating DC Rectifier from 12V 8000A High Power High Current Anodizing Rectifier
STP Series Electroplating DC Rectifier Model: STP - 012 - 8000TW | ||||
| ||||
Overview | ||||
STP series DC rectifier is a rectifying type DC power supply based on high frequency switching technology of IGBT switching components. It is a product specially developed by our company for industrial applications such as electroplating, electrolysis, water treatment and hard oxidation. Compared with the traditional thyristor rectifying power supply, this series of rectifier power supplies can reduce the clients' power consumption by 20%~30%. In order to overcome the harsh environment of the applications and the long-term running conditions, the rectifier power supply is basically water-cooled, also the three-proof treatment adopted for the internal components which can achieve effective heat dissipation of the power supply and protection of the internal components of the rectifier. This series rectifiers can cover all the above-mentioned applications, featured for complete control functions, stable performance and high cost performance. | ||||

Technology advantages | ||||
| ||||
Main components | ||||
IGBT | ||||
Infineon (the original Siemens) IGBT module. | ||||
Three-phase bridge rectifier | ||||
SANREX bridge rectifier. | ||||
Main Transformer | ||||
High-frequency Nano crystalline transformer. The transformer is a case type structure. This case is not only the protective layer, but also the output of the transformer, and it also can provide cooling water channel. Another advantage is its large conductive area, small heat. Because the transformer adopts the novel structure, the conformity of production produced is high; it is especially suitable for high power supply manufacturing. | ||||
Output rectifier diodes | ||||
AN (original Motorola) Schottky. | ||||
Heat sink | ||||
Good quality aluminum panel, thickness up to 42mm | ||||
Output copper bar | ||||
99.9% non-oxidation red copper, designed flow ability beyond 2.5A/m2 | ||||
