DLC7000C pulse power supply has single positive pulse and double positive and negative pulse power supplies, using unique modulation technology and digital control. The positive pulse opening width (T+) and the negative pulse opening time width (T-) can be adjusted in the full cycle respectively. Positive current, voltage regulation, negative current and voltage can be adjusted independently. Can fully meet the different needs of customers. It is suitable for gold plating, silver plating, nickel plating, tin plating, etc., which can significantly improve the coating performance; when used for protective-decorative electroplating (such as decorative gold), it can make the coating color uniform, good brightness, and strong corrosion resistance. In particular, the anodization and dissolution of the reverse pulse of the dual-pulse power supply makes the metal ion concentration on the cathode surface rise rapidly, which is conducive to the use of high pulse current density in the subsequent cathode cycle, so the coating is dense, bright, and low porosity; the dual-pulse power supply The reverse pulse anode stripping greatly reduces the entrapment of organic impurities (including brightener) in the coating, so the coating has high purity and strong discoloration resistance.

In the pulse electroplating process, when the current is turned on, the pulse (peak) current is equivalent to several times or even dozens of times of the ordinary DC current. It is this instantaneous high current density that causes the metal ions to be reduced under extremely high overpotentials. , So that the grains of the deposited layer become finer; when the current is turned off, the discharged ions near the cathode area return to the initial concentration, and the concentration polarization is eliminated. This 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 shutdown period, there are phenomena such as recrystallization, adsorption and desorption that are beneficial to the deposited layer. Such a process runs through the beginning and end of the entire electroplating process simultaneously, and the mechanism contained therein constitutes the most basic principle of pulse electroplating. Practice has proved that the pulse power supply has incomparable advantages over traditional DC electroplating in terms of refining crystallization, improving the physical and chemical properties of the coating, and saving precious metals.

The dual-frequency power supply is a new type of power supply. Due to the reasonable processing of high-frequency pulses and low-frequency pulses, the application fields of switching power supplies are expanded.

1. Single pulse power supply:

Single-pulse power supplies generally output a one-way pulse current with fixed parameters. If you want to change the pulse parameters, you need to reset it after shutdown.

2. Double pulse power supply:

The dual-pulse power supply generally outputs periodic commutation pulse current with fixed parameters. If you want to change the pulse parameters, you need to reset it after shutdown. ...

3. Multi-pulse power supply:

Multi-pulse power supply refers to intelligent multi-group periodic commutation pulse electroplating power supply, which can cyclically output multiple groups of unidirectional or periodic commutation pulse currents with different parameters such as pulse width, frequency, amplitude, commutation time, and duration. Since the structure or composition of the coating obtained by using different parameter pulse currents is different, choosing appropriate pulse currents with different parameters alternately for electroplating is expected to obtain a micro-nano metal multilayer film coating with excellent performance. The DLC7000C intelligent pulse electroplating power supply provides a powerful means for the development and production of nano electroplating technology。

◆ Cyclic output of ten groups of current waveforms with different parameters, each group of current can be arbitrarily selected among the waveforms of DC, single pulse, double pulse or DC commutation.

◆ The duration of each group of current can be arbitrarily selected from 1S to 9999S, which is convenient to control the thickness of the coating obtained by each group of currents.

◆ During the alternate operation of each group of pulse current, the average current is always the same to ensure that the peak current of each group of pulses is different when using different duty cycles.
