Dual pulse power supply is the latest generation electroplating power supply product, also known as flat wave/bidirectional pulse adjustable switch power supply; It rectifies the power frequency AC power into a DC high-voltage power supply, generates a low-voltage high current power supply through high-frequency voltage conversion and high-frequency rectification, and then filters it into a pure DC power supply through LC. It is then sent to an asymmetric full bridge conversion circuit (also known as a chopping circuit) to generate an artificial flat wave (i.e. pure DC) or bidirectional pulse square wave output.
The main transformer is an efficient and energy-saving transformer independently developed by Tongke Electric. It uses nanocrystalline soft magnetic materials as the main transformer core, with a large overcurrent area, good cooling effect, excellent coupling, low operating losses, and a service life of more than 10 years; The main power component of the power supply is a high-power original imported Infineon insulated gate bipolar transistor IGBT module, with high-quality material selection to ensure quality. The output mode is full bridge full wave output, PWM control. Using RS-485 protocol for remote control is more convenient than traditional host control, reducing host losses; According to customer needs, LCD touch screens can be selected to avoid button and adjustment knob malfunctions caused by long-term operation in harsh environments. Equipped with five protection methods, including overheating, overcurrent, overvoltage, short circuit, and fault, to minimize the probability of equipment damage.
Double pulse power supply provides finer electroplating and better smoothness than single pulse power supply. The anodic dissolution of the reverse pulse of the dual pulse power supply causes a rapid increase in the depth of metal ions on the cathode surface, which is beneficial for the subsequent cathode cycle to use a high pulse current density, resulting in a dense, bright, and low porosity coating; The anodic stripping of the reverse pulse of the dual pulse power supply greatly reduces the inclusion of organic impurities (including brighteners) in the coating, resulting in high purity and strong color resistance of the coating.
