Electrophoretic coating DC power supply is mainly used in electrophoretic coating production lines such as automobiles, motorcycles, household appliances, metal casings, as well as rectifier power supply in situations with similar technical requirements. Its purpose is to create a dense, uniformly thick, smooth and highly adhesive paint film on the surface of the workpiece, in order to prevent rusting and extend its service life. Therefore, the rectifier used for electrophoretic painting is one of the key equipment specialized for painting production lines. This device is a dual closed-loop automatic control system consisting of a voltage outer loop and a current inner loop. Therefore, the voltage regulation accuracy is high, the current limiting characteristics are good, and the operation is safe and reliable. The starting, running, and stopping operations of the device are simple and convenient, achieving automatic soft start (automatic boosting) and automatic soft stop (automatic reducing) when starting and stopping. When there is a malfunction during operation, it automatically protects and blocks pulses, displays fault point signals and alarms. Composed of a microcomputer dual control system, the dual control system operates one way and online hot backup one way. When a fault occurs in the working system, the self diagnosis system automatically detects the fault without disturbance and switches to the hot backup system. The power equipment continues to operate according to the original set parameters without stopping or stopping production.
