Micro Arc Oxidation Power Supply KWYS Series - Leading China Suppliers & Factory for Advanced Coating Solutions
Product Feature
It has the functions of input overvoltage and undervoltage, output voltage limiting, current limiting, overcurrent, overvoltage and overheating protection, and has the functions of power supply phase loss, component overtemperature, quick melting, overcurrent cutoff, current limiting and short circuit protection and sound-light alarm.
Three-phase alternating current is output through a rectifier transformer, and two groups of thyristors are used for rectification at the valves; The latter stage adopts IGBT chopper technique, which makes the output have three modes: DC, DC superimposed pulse and asymmetric AC pulse.
Using DSP control technology, the output waveform and duty cycle can be set at will; The output stability accuracy can be higher, especially in the low current state; The workpiece ablation can be judged intelligently by single chip microcomputer, and the workpiece can be effectively protected.
The whole equipment has reasonable structural design, beautiful appearance and easy maintenance. In order to ensure that the equipment can work in corrosive gas media such as acid, alkali and humidity, the electrical control part adopts isolation measures, and the control trigger plate is sealed with plexiglass box. Ensure the long-term reliable operation of the equipment.
The upper limit of the working current of the power switching element is increased by more than 2 to 3 times through the dynamic current sharing parallel technology, and then its reliable operation is guaranteed by the residual energy elimination circuit. The two technical approaches closely converge to form an overall technical route, which ensures the maximum application power of the equipment, thus establishing a more optimized preparation process of light metal surface functional film, promoting the application of light alloy in weapons and equipment, automobiles, medical care and other fields, and realizing the large-scale production demand of its products.
