A plating power supply is a direct current device that converts industrial frequency alternating current into different voltages, frequencies and waveforms. Determining the size and type of power supply for a plating type and all its tanks is the first and most important task in plating production.

The first is to meet the specifications of the plating process, including the power of the power supply, the waveform index, the adjustable range of current and voltage values, etc. 
The second is the reliability of the power supply itself, which mainly refers to the structure, line characteristics, and the reasonableness of the cooling method. At the same time, we should also consider its price performance, to determine how large and what kind of power supply should be configured for a plating type and all its plating tanks is the first and foremost important work in the implementation of plating production. There are two ways to determine the power supply for plating in actual production: one is the volume current density method, which is based on the capacity of the plating solution, and the other is the unit area current density method, which is based on the plated area.
 
After determining the power size of the power supply, the electroplating power supply should be based on the needs of the plating process and the conditions of the plating site to choose the waveform of the electroplating power supply, cooling methods, size and corrosion resistance, including cost factors to balance.
