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 %.
This product is used in plasma technologies.
The equipment can be operated between 5°C and 40°C with a primary cooling water at 30°C maximum (200 m3/h) in a non-condensing 5-85% relative humidity. The IN/OUT airflow through the hosting room should be 15.000 m3/h.
A special care must be taken against dust, and especially metallic dust, that can initiate electric arc and high damages to high voltage parts. So in some industrial environment, it might be worth to install the DC power system inside a controlled atmosphere room.
Excepted the 6-monthly routine visual checks of the main components and the monitoring of the dust on the high voltage and electronic parts, the system does not require specific physical maintenance.
The availability of the system nears 99%. In option, a few parameters (like ambient and inlet temperatures), can be recorded and monitored remotely with alarms to enhance this availability.
As all our products, the PLASMA TORCH Power Supply System can be fully customized and adapted to every client requirement.
