Tips: The constant current characteristic of three phase plating rectifier

As a kind of electroplating rectifier power supply, the three phase plating rectifier can be divided into two output states: Constant voltage and constant current. The output of current can be adjusted in constant voltage, and the output of voltage can be adjusted in constant current. In general, the power supply is designed to be able to deliver voltages and currents within a certain range. For example, a power supply can output a rated DC 12V and a DC current of 0 to 100 milliamps or 0 to 0.1 amps. The output of the power supply may experience current fluctuations etc. but the output voltage will remain unchanged.

Electroplating rectifiers do not use a constant voltage power supply with a constant voltage and fluctuating current in most electroplating applications. On the contrary, most electroplating uses a constant current power supply with a constant current flow and a freely fluctuating voltage. The plating thickness is the power supply current to On-time evaluation criteria, such as the current density of many gold-plating processes, is about 3.0 amperes per square foot (one foot is 0.3 meters). By controlling the current time, the thickness of the coating can be accurately controlled.
