The Excelitas E-Gun High Voltage Power Supply is a highly regulated power supply designed for use in an electron-beam system. The supply provides high voltage for the electron beam emitter, filament power and closed-loop emission current control. High frequency power conversion technology is used for all power supply functions. The unit is designed to run continuously at full output.
The high voltage output of the supply is single-ended, and can be varied from near 0 to negative 125 kV. Maximum emission current is 58.0 mA at full output voltage.
Emission current regulation is achieved through control of emitter’s filament current. Maximum filament current is 18A into a 1 ohm load.
The power supply is comprised of a Converter Assembly and a High Voltage Tank Assembly. The High Voltage Tank Assembly is filled with oil for purposes of electrical insulation and cooling.
Control of the power supply is performed by 15 V or 24 V interface signals supplied by the customer.
Extensive internal interlocks and diagnostics are incorporated to provide reliable and safe operation, as well as to facilitate installation
