Low Ripple 1000A 80V DC Rectifier for Industrial Coating Applications

Coating technologies are widely used to improve corrosion resistance, durability, and surface performance of metal components. Among them, E-Coating, CED coating, and PVD coating represent three of the most commonly adopted processes in modern industrial surface treatment.

The electroplating coating rectifier is a DC power supply used in industrial plating lines. It keeps current stable over long working hours. That stability is crucial for uniform coating and smooth surfaces.

You’ll find it in metal finishing workshops, automated plating lines, and custom surface treatment setups.

AC power first goes through a three-phase transformer. Then it’s converted to DC using silicon diodes. This simple setup works reliably for most standard plating processes. Maintenance is easy, and performance is steady.

SCR (thyristor) rectifiers handle higher current jobs. Adjusting the firing angle changes output current and voltage. This helps when the plating process has multiple stages.

High-frequency switching rectifiers are common on modern automated lines. They use high-frequency switching to convert and isolate power. The output is stable with low ripple, while the units are smaller, lighter, and more efficient than older models.

Manufacturers widely use high-frequency rectifiers for surface treatment and electroplating applications, including copper, nickel, zinc, chrome, gold, and silver plating on PCBs, electronic components, automotive parts, precision or aerospace components. These rectifiers offer energy-efficient operation, low ripple for improved coating consistency, compact design to save workshop space, and built-in controls for automated processes.
