Pulse Plating & Pulse Plating Reverse rectifiers are designed to handle forward and reverse pulsed output current with the possibility to create, via software, special mixed waveforms with DC & pulsed output current. These rectifiers are able to generate very fast and complex current and voltage patterns (repetitive sequence of pulses) where minimum pulse (phase) duration is 1ms. Using these fast pulse patterns in combination with appropriate chemical products, remarkable improvements are obtained.

Pulse Electro Deposition (PED) is widely used to improve the electrochemical process. The potential or current is alternated swiftly between different values with the aim to lower the effect of a charged layer forming around the cathode. In PCB manufacturing the combined use of additives and reverse current pulses, improves the uniform distribution of metal on sharp edges. The application are varied: PCB, anodizing, micro-plating, etc. Applications of PED are object of research, and many other uses of this technology may yet be discovered. Generally speaking, there are no limits to pulsed applications. While are not specialized on the chemistry of plating we can propose power supply solutions that best fit your applications.

Multi-tower configuration
Multi Tower is needed if the input main current is more than 230Arms. Multi Tower systems can be controlled individually with one tower designated as the Master to synchronize the pulse or one control point thru the Master Box.

• RS232/RS485 converters required if more than 3 towers
• RS232/RS485 converters required if more than 3 towers
• only one output pole can be interconnected
