AC and DC Power Supply for Aluminum Profile Coloring - Quality Solutions from China Suppliers and Factory
Product Feature
It uses IGBT as the main power switching element, with imported drive and high-performance rectifier tube and non-inductive capacitor. It is a new power supply with high efficiency, energy saving, reliable performance, compact structure and simple operation. It is widely used in electrochemical fields such as surface treatment and electrolysis.
Using inverter technology, its power factor is very high, and it can reach above 0.93 without reactive power compensation. The harmonic content is also small. Rectification effectively reduces the on-state pressure drop, improves the efficiency of the machine and saves energy. The characteristics of high efficiency and high power factor make it save electricity by 20% compared with ordinary SCR rectifier.
The technical process is from Korea KooSoo Heavy Electric Co., Ltd, and it is controlled by servo motor with high accuracy.
High coloring uniformity, automatic and flexible color supplement and color difference reduction, high evaluation rate and long-term stability.
The new coloring power supply independently developed by our company is suitable for coloring process of different colors, and different waveform process programs can be selected. In the past, the output waveform was single and not adjustable, and it took a long time to color dark materials. In order to improve this defect, an asymmetric waveform (different from similar waveforms) output function was added. And can be applied to single and double salt coloring processes.
The switching power supply is designed for electromagnetic compatibility, which does not affect the normal operation of other equipment on site.
The imported driving circuit greatly improves the reliability of operation.
All raw materials and devices have been strictly screened and aged, and the design limit is constantly challenged by destructive examination in the production process. The "three-prevention" treatment and isolation measures against salt fog acidification are adopted, and the protection functions such as overcurrent, overheating and overvoltage are provided to ensure the high reliability of the power supply in harsh environment.
