ULTRAVOLT® INTRODUCES NEW LINE OF FLOATING HOT DECK POWER SUPPLY SUBSYSTEMS

RONKONKOMA, New York -- May 30, 2008 -- UltraVolt, Inc., the world-leading manufacturer of standard-product DC-to-DC high-voltage power supplies, today announced an enhanced series of floating-hot-deck power supplies. “EFL” Series modules are isolated power supplies featuring isolation up to 15kV, along with analog & digital I/O. Therefore, “EFL” Series modules create a completely integrated floating-hot-deck subsystem.

Floating hot decks operate multiple bias supplies, pulse generators, and control systems in E-beam, I-beam, and mass-spectrometer systems.

While UltraVolt’s original floating-hot-deck power supply, the “FL” Series, provides one analog up channel, the new “EFL” Series provides a second analog up channel and improved input / output faraday shielding along with upgraded low-voltage (LV) output power and analog channels.

The improved input / output faraday shielding reduces power-stage coupling noise. The upgraded LV output power provides tightly regulated ±15VDC @ 50mA and +5.1VDC at 500mA. The main output is now available at 12V 1 amp or 24V 1 amp / 1.5 amp.

The upgraded analog channels auto-zero and auto-correct for linearity errors and full-scale gain. This provides a control & monitor capability of 0 to 10VDC with a temperature coefficient of <10ppm per °C. These analog channels have an initial offset error of <1mV and a full-scale gain error of <0.1% while keeping the linearity error to <0.1%.

As a result of all of its enhancements, the “EFL” provides higher performance than the original “FL” Series modules on critical analog control specifications such as gain error 0.2% vs. 2%, linearity 0.5% vs. 1%, and temperature coefficient of 10ppm vs. 50ppm (“EFL” Series vs. “FL” Series, respectively for each comparison).

“UltraVolt is very excited to offer the enhanced “EFL” line with these new capabilities" said James Morrison, Executive Vice President. "With the “EFL’s” PPM level I/O performance and main outputs of up to 36 watts, we can offer our customers the smallest fully featured floating-hot-deck subsystems in the high-voltage industry.”
