The glow discharge power supplies of the GLOWTEC series are switch-mode power supplies that work with the state-of-the-art current fed converter technology. By the use of this technology the output of the power supply acts like a current source, which is ideal for the use in glow discharge and high voltage plasma processes. Current, voltage and power reach excellent precision due to digital regulation.
Each of these power supplies comes with an integrated configurable arc management. For simple DC glow discharge processes the GLOWTECDC is the right choice. It limits the output current by a resistor. For more sophisticated DC processes a patented and optionally integrated arc current limitation is available. It restricts the output current to max. five times of the nominal current during an arc.
TWO MORE DEVICES IN THIS SERIES: THE GLOWTEC DCp AND THE GLOWTEC AC
