15kW Simba 2 Power Supply controls up to 3 guns
The Temescal Simba 2 electron beam power supply is a constant-voltage power supply capable of continuously delivering -10 kV at 1.5 amperes as well as filament power for up to three electron beam sources. The entire 15-kW high-voltage output can be delivered to one electron beam source or shared with up to three sources operating simultaneously in one, two, or three vacuum chambers. Compatible with sources featuring either permanent-magnet or electromagnetic deflection, the Simba 2 power supply offers stable output at all voltage levels, rapid arc recovery, ease of integration, and safety and convenience for operating as well as service personnel.
Available Options:
- Single Gun Control Simba: 208/240V, 380/415V or 480V
- Two Gun Control Simba: 208/240V, 380/415V or 480V
- Three Gun Control Simba: 208/240V, 380/415V or 480V
Technology
Multiple voltage and current ranges enhance the versatility of the Simba 2 power supply. The power supply operates in user-selectable voltage ranges of -3 to -7 kV and -6 to -10 kV. Voltage output is linearly adjustable within each range and regulated to within +1%. The gun control circuit enables the user to define four emission current ranges for each electron beam gun, ensuring excellent low-power stability. Each gun’s emission current is fully adjustable within each range and independently regulated to +1%.
- 15kw of high-voltage output for simulataneous operation of up to three electron beam sources.
- Rack-mountable controls
- Optional interface for control by host computer
- Constant voltage in two user-selectable ranges
- Linearly adjustable voltage output
- Current control programmable in four ranges, ensuring excellent low-power stability
- Adjustable arc supression settings on HV regulator
