Advanced Energy / HiTek EG353 Power Supplies

Advanced Energy / HiTek EG353 Power Supplies are 35kV high voltage power supplies designed for Scanning Electron Microscopes (SEMs). These power supplies offer built-in flexibility to accommodate various Schottky emission electron gun configurations. The EG353 power supplies feature Direct Drive Digital Control (D3C), which enables a wide range of operational and diagnostic capabilities through an intuitive GUI. These power supplies feature low ripple (<1.6ppm, accelerator), high stability (<10ppm, accelerator), and a 5A time delay internal PCB-mounted fuse for protection. The EG353 power supplies can be easily installed with flexible module and rack-mount options. Typical applications include SEM and electron microscopy using Schottky emission electron guns with LaB6 or CeB6 cathodes and systems with >1nm to <20nm resolutions.
