About pulse power supply

Firstly, after slow energy storage, the primary energy has enough energy, and then charge the intermediate energy storage and pulse forming system. The energy is stored, compressed and pulsed. After digital processing, it is quickly discharged to the load. In the pulse process of pulse power supply, when the current is on, the pulse (peak) current is equivalent to several times or even dozens of times of ordinary DC current. It is this instantaneous high current density that reduces metal ions under extremely high overpotential, so as to make the grain of deposition layer thinner. When the current is turned off, the discharge ions near the cathode area return to the initial concentration and the concentration polarization is eliminated, which is conducive to the continuous use of high pulse (peak) current density in the same period of the next pulse. At the same time, during the turn off period, there are also phenomena such as recrystallization, adsorption and desorption beneficial to the deposited layer. Such a process runs through the whole electroplating process at the same time, and the mechanism contained therein constitutes the most basic principle of pulse electroplating. Practice has proved that pulse power supply has incomparable advantages over traditional DC in refining crystallization, improving physical and chemical properties of coating and saving precious metals.

Product features

1. The single pulse power supply is suitable for electroplating gold, silver, nickel, tin, copper and their alloy materials, which can significantly improve the functionality of the coating. It is used for protective and decorative electroplating, which can make the coating uniform color, good brightness and strong corrosion resistance. When pulse power supply is used for precious metal purification, the purity of precious metal is higher.

2. The adjustable single pulse power supply uses the color touch screen human-machine interface display control, and the operation is simple, intuitive and convenient.

3. The touch screen man-machine interface has the functions of voltage or current setting, frequency setting, duty cycle setting, multi period setting, etc.

4. Touch screen man-machine interface has external communication interface. Equipped with RS-485 (Modbus Protocol) local control and remote control switching function.

5. The power host has the advantages of small volume, light weight, elegant appearance, convenient installation, safe use, anti-corrosion and durability

6. The power supply has protection functions such as overheating, overcurrent, short circuit, undervoltage and overvoltage.

7. High power factor, stable output frequency, high control accuracy, high voltage and current output stability can effectively improve product quality.
