UltraVolt Introduces New Line Of Floating Hot Deck Power Supply Subsystems

June 05, 2008 by Jeff Shepard

UltraVolt, Inc. 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 1A or 24V 1/1.5A.

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%.

"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."
