Cheetah ST- 4/6/8/10
-
maximum power 4/6/8/10 kW, power regulation is done by semiconductor devices ( „switch mode“)
-
robust IGBT inverter für maximum reliability
-
special electronics with integrated arc-counter and sensor for the length of the arc allows shortest recovery times and safe switching-off at critical conditions
-
adjustabe high voltage from 0 to -10kV (0 to –8kV for the ST-4 ); extremely stable regulation (<0,05%) for a minimized focus of the beam
-
stability of the emission current: <0,5%
-
remote control via integrated PLC interface or optional remote control module for adjustment of high voltage and emission current
-
very compact and light, installation in a 19“ rack: ST-4/6/8: high voltage module: 5 units high, control module 1 unit high
-
programmable sweep module „Cheetah“ is standard for ST-6/8/10, an analog sweep module for the ST-4, each is 2 units high (1unit=1,75“)
-
air cooling for all models
