UltraVolt Inc. is offering several families of standard-product, microsize and micropower high-voltage power supplies. The miniature and lightweight models offer low ripple, tight line and load regulation, programmable output and output current-limit protection. Some models perform voltage monitoring to 10 ppm. Applications include avalanche photodiodes, photomultiplier tubes, microchannel plates, image intensifiers, electrostatic chucks, scanning electron microscopes and mass spectrometers. Output voltage ranges from 0 to 100 V through 0 to 8 kV at 100 mW to 6 W of output power, with output currents from 30 μA to 6 mA.
