DC/DC power supply EMC

with overload protectionwith overheating protectionwith overcurrent protection

The EMC series of Wisman high voltage power supplies are comprehensive multi-output high voltage power supplies for focused ion beams. Typical applications include transmission and scanning electron microscopy; semiconductor analysis, milling and repair of optical disc drive heads, ion; beam etching and focused ion beam lithography. The modular design approach allows individual components to be easily configured in a common rack-mounted assembly on a large chassis. Interface, logic and control circuits are manufactured using surface mount technology to minimise cost and size. Integrated accelerating power supply, filament power supply, absorber power supply, suppressor power supply and lens power supply. Low output ripple, excellent tuning ratio, stability, temperature drift and accuracy. Wisman's unique high voltage suspension and digital control technology. the EMC series of high precision modules are competitively priced and ideal for OEM applications.
