Description

Scanning features allows for independently controlled scanning speed and range. All settings can be manually adjusted or can be stored and recalled automatically after unit switch on. The unit also features a built in timer and automatic standby mode. The ES40-PS can be supplied as a full width 19″ rack mounting unit (3U height) or free standing. Easy firmware update via USB port. Unit can be remotely controlled via RS232/485 or Ethernet interfaces. Autosave function for saving your parameters/unit preset and applying them automatically after restart.

Application

The ES40-PS power supply is intended to use with the ES40C1 Low Energy Electron Source or Double Pass Mini Cylindrical Mirror Analyzer CMA 40CF. The power supply allows fine adjustment of the electron beam profile to achieve a small spot at high energy and emission currents.

Options

– Software control (Version Pro, Extended or Library Module),
– Analog I/O card for vacuum measurement (1 gauge).
