Spellman's provides a new EBM-TEGR rack mountable triode high voltage power supply for the thermionic scanning electron microscope.
FREMONT, CA: The increased demand for electricity in electronic equipment necessitates the development of more effective cooling techniques to prevent overheating. Application crashes, frozen screens, and even complete device shutdown can result from overheating owing to poor thermal management. Effective cooling of electrical equipment requires thermal control via conduction. Spellman High Voltage Electronics Corp, the world's leading manufacturer of high voltage power supplies, X-Ray generators, and Monoblock® X-Ray sources, offers the latest triode high voltage power supply designed to drive Thermionic Scanning Electron Microscopes (SEM). The new EBM-TEGR features digital communication, a 19" rack-mount chassis, and increased output power at the Accelerator/Grid Outputs. Spellman's patented packaging and encapsulating technology benefit size, cost, and performance compared to competing SEM power supply alternatives.

Programmable up to -30kV at 400uA, the EBM-TEGR provides a high-precision, low-noise, ultra-stable Accelerator supply. This, together with Floating Filament and Grid supplies associated with the Accelerator, regulates the beam. The unit also contains grounded PMT, Scintillator, and Collector outputs for driving the Detector with high voltage. The customer digitally controls this integrated EBM-TEGR power supply system via an RS-232 or optional RS-485 interface. There are five interlocks offered.
Spellman's broad application expertise and distinctive design capabilities have enabled the development of a comprehensive variety of high precision, low noise, ultra-stable technology platforms that can be tailored to satisfy the stringent criteria of Thermoelectronic SEM. Among these are the EBM-TEG, the EBM20N5/24, and the EBM-TEGR. In addition, our global technical support centers provide customers with timely local responses to their demands.
The units are protected against overcurrent, overvoltage, arc, and short circuits. Moreover, they are UL, UKCA, and RoHS compliant. OEM customizations are available.
Spellman High Voltage Electronics is the leading provider of AC-DC and DC-DC high-voltage power converters and Monoblock® X-Ray sources for medical, industrial, semiconductor, security, analytical, laboratory, and under-sea cable power-feed applications.
