TXF1210
The Teslaman TXF1210 Series is an integrated, multi-output high voltage power supply designed specifically for scanning electron microscope (SEM) drivers. The acceleration section is a highly stable 30kV power supply, integrated with suspended filament lamp source, lead-out power supply and suppression power supply, which can be installed in a 19-inch rack. All outputs provide ultra-low output ripple, minimal micro-discharge, excellent regulation, stability, temperature coefficient and precision specifications for higher image quality and resolution requirements. Suspended power supply is provided through Teslaman's proprietary high voltage isolation technology. Customer control of this integrated TXF1210 power supply system is accomplished through optical fiber RS-232 interface. All security interlocks are based on fail-safe hardware design. UL and CE certification can be carried out.
Typical Application：Scanning electron microscope (SEM), Electron beam controller.

Product Specifications
Input
+ 24VDC, ± 5%, 4A. Surge current < 6A is suitable for 1 second.
Vacuum interlocking device
Vacuum interlocking is an optical interlocking, which works when light exists in optical fiber. When no light is present, this interlock does not work and this power supply turns off all outputs.
Front Panel Indication
Turn on
A green LED indicates the presence of + 24V power supply. It will be lit in the range of 22.8 to 25.2 V, and will flash for 1 second when it exceeds the range.
Vacuum Interlock
Yellow LED indicates that vacuum interlock is closed. The vacuum interlock must be lit to generate high pressure.
Test GUI
A product GUI can be provided free of charge to customers for testing and development work.
Protection
All outputs are protected against arc in the load and continuous short circuit to ground and each other. All low voltage inputs have over-voltage protection of ± 30V. The power input has over-voltage protection and reverse connection protection. If BeamEnergy has more than a 'A' arc during a nominal 'B' time (seconds), the unit will disable all outputs and set all programming to zero. If there are fewer than 'A' arcs, the unit will continue to run. The default values are A=8 and B=10. Both 'A' and 'B' can be set through optical bus commands and GUI. If the over-temperature condition exceeds 10 seconds, all outputs will be disabled. This unit reports fault or trip conditions through status flags. After a trip occurs (arc, over-current, over-voltage, over-temperature, etc.), the unit can be reset by software (fiber bus command) or power cycle.
