UltraVolt, Inc., has announced the extension of its EFL Series of enhanced floating “hot-deck” isolated power supplies. EFL Series units were originally offered up to 15kV of isolation; now the line can achieve up to 30kV of isolation. The EFL Series of “hot-deck” isolated system modules are already know for simplifying designs that have electronics highly isolated and/or truly floating on high voltage. Designers just apply power, signals, and controls to the module and have an output isolated by 150GΩ (15kV) or 2GΩ (30kV), and AC leakage capacitance of <40pF (all models). The new 30kV version of the EFL Series achieves a 100% increase in withstand voltage in only a 5.7 in3 increase in volume.

With this single encapsulated module, users have 30kV isolated low-voltage power sources of +12 or +24 VDC, ±15VDC and +5VDC as well as two analog I/O channels, and one digital I/O channel. The new 30EFL maintains the EFL Series enhanced performance, which includes analog channel initial offset error of <±2mV, gain error of <±0.2%, linearity error of <±0.5%, and a temperature coefficient of <±10ppm.

Typical applications for the EFL Series include some of the world’s most advanced devices, such as: scanning electron microscope (SEM) image and inspection systems and tools, focused ion beam (FIB) tools, medical patient diagnostic / patient treatment equipment, and mass spectrometers. Uses for EFL modules in these applications are stacking / floating high-voltage power supplies, floating precision filaments, floating bias supplies for detectors, floating gate supplies, floating LVPS for powering fiber optic links, and floating precision bias supplies.

“UltraVolt continues to offer new products for users requiring complete, proven solutions to address key time-to-market challenges”, said James Morrison, CEO and Co-Founder. “The EFL Series expansion to 30kV gives our customers a complete floating sub-system with precision controls at double the current working voltage. The EFL Series enables our customers to get the job done - to highly isolate electronics from ground and even to power and operate floating electronics with continuous high voltage bias of 30kV. With this unit, we continue Making High Voltage Easier® by meeting the needs of our customers’ diverse applications.”
