Flood Source Power Supply FS40A-PS


The FS40A-PS power supply allows fine adjustment of all instrument parameters for achieving a wide range of beam profiles; no additional electronics are required. All adjustable parameters are displayed on the large, high brightness LCD display. All settings can be stored and recalled automatically after unit switch on, or else manually adjusted. The unit also features a built in timer and automatic standby mode. The FS40A-PS can be supplied as a full width 19″ rack mounting unit (3U height) or free standing. Unit can be remotely controlled via one of available interfaces.


The FS40A-PS power supply is designed for use with the FS40A1 Electron Flood Sources which are used for charge neutralization of insulator and semiconductor samples in XPS/AES and SIMS applications.


- Software control (Version Pro, Extended or Library Module).
