Aircooled plasma generators

  • plasma



The generator construction of the production series RGB-Plasma-Puls-LK is designed for the special requirements of the plasma ionisation process. This is characterized with a high power rectifier, adjusted LC-intermediate circuit and modular IGBT-pulse unit. The intelligent control device of the RGB-Plasma-Puls-LK also consists of a high speed arc-control management to protect the coated products.

// Optional with RGB-Bipol-Power 
// Integrated electronic switch of DC output polarity

// Single devices from: UDC = 400 - 1.500V / IDC = 40 - 1.000A
