JEMA SA delivers PLASMA Power Supplies Systems, both for heating in reverse metallurgy applications or for coating/sputtering in CVD or PVD applications.
JEMA SA PLASMA Power Supply Systems:
convert AC into DC both controlled in current and voltage.
manage the entire arc initiation, propagation and stick to nominal and stable conditions as given by the plant control.
are composed of a few cabinets that are usually located in an environment controlled room separated from the main process.
are fitted with all necessary protection and feed-back signals.
achieve a global efficiency above 95 %.
Maintenance is limited to a routine visual check of the main components and the monitoring of the dust on the high voltage and electronic parts.
The availability of our systems approaches 99%.
Like all our products, the PLASMA Power Supplies Systems can be fully customized and adapted to every client requirement.
The HEATING PLASMA TORCH Power Supply System transforms a 3 x 15.600V INPUT into a controlled 0 to 1700 Adc and 0 to 2500 Vdc characteristics (up to 3 MW). The set point in both voltage and current are given by the plant control system and the PLASMA TORCH Power Supply System regulates its inner choppers to achieve those set points.
In addition, upon the start order from the plant control, the HEATING PLASMA TORCH Power Supply System manages the entire arc initiation, propagation and fix to nominal and stable condition as given by the plant control.
In nominal conditions the HEATING PLASMA TORCH Power Supply System achieves a global efficiency of 96,6 %.
