Product Applications

This power supply is designed to deliver a single, well-defined pulse of DC power for specific tasks, making it particularly valuable in areas where precise timing and voltage control are essential.

Metal Polishing

The 40V 7000A DC power supply is a specialized power supply used in electroplating applications. Electroplating is a process that involves depositing a layer of metal onto a surface using an electric current. The process requires a constant and steady current to achieve a uniform deposition of a thin layer of metal on the surface. The 40V 7000A DC power supply provides the necessary current and voltage required for the electroplating process.
