FIL-5V-3A is designed for of beam applications from electron guns to ion beams in devices such as scanning electron microscope inspection tools, focused ion beam workstations, and mass spectrometers
UltraVolt has announced the introduction of the FIL-5V-3A precision filament supply (FIL Series).
The FIL-5V-3A is a precision, centre-tapped, non-isolated, low-voltage filament supply rated for 0-5VDC at 0-3amps.
UltraVolt's precision filament supply operates in either constant current regulated mode or constant voltage regulated mode.
In constant current (CC) mode, the current control sets output current and the voltage control sets the voltage limit.
In constant voltage (CV) mode, the voltage control sets the output and the current control sets the current limit.
Units feature automatic crossover between CC and CV modes.
FIL series modules also meet important specs.
Output load regulation is less than 0.5%, no load to full load, in CV mode and less than 0.05% in CC mode, short circuit to full load.
Between +26.4VDC and +21.6VDC, output line regulation is less than 0.01% in either CV or CC mode.
Units currently exhibit a temperature coefficient of 15ppm/C in CC mode.
"The new FIL Series gives our customers exactly what they have been asking for - a high level of precision in a filament supply, without the precision prices!" said James Morrison, executive vice president.
"The device can be used by innovative beam supply engineers with other precision UV devices such as the E Series to advance their designs to never-before-realised levels of stability, repeatability and accuracy".
Units are available with several options, including mu-metal, wrap-around shielding; an eared mounting plate; finned heat sinks (especially for PCB mounting); an RF-tight aluminum case; and the -R6 option for full RoHS compliance.
