ULTRAVOLT® EFL SERIES ENHANCED FLOATING HOT DECK LOW-VOLTAGE POWER SUPPLIES WITH ISOLATED DIGITAL AND ANALOG I/O Enhanced floating hot deck low- voltage power supplies The EFL series of floating hot deck, low-voltage (LV) power supplies offers an integrated solution for systems requiring LV power and controls with high voltage isolation. Combining a highly isolated, DC-to-DC, multi- output low-voltage power supply (LVPS) with an advanced isolated digital and analog I/O topology, the EFL sub- system provides both power and controls to floating-hot- deck circuitry. This solution, when combined with one or more UltraVolt® HVPS or other circuitry, can provide high- performance solutions for a variety of applications. Features Typical Applications › Precision analog control › Floating/stacked ion or e-beam biases › Linearity of ±0.05% and accuracy of ±0.2% › Floating filament bias › 10ppm temperature coecient › Floating pulsers and gated grids › Isolated up to 15 kV or 30 kV › Floating capacitance meters › Isolation resistance of 150 GΩ (15 kV) or 2 GΩ (30 kV) › Floating high side current monitors › 4 regulated floating LV power outputs › Floating leakage testers › Isolated digital and analog I/O to and from floating hot deck NORMAL, HALF-QUIET, AND QUIET MODES All EFLs feature a mode control. Three different models—normal, half-quiet, and quiet—are selectable via the voltage level at the mode pin. A voltage between -1.0 and +0.8 V keeps the unit in normal mode; the up and down analog channels follow their inputs. If the mode feature is not used, the mode pin must be grounded for the EFL to operate properly. A voltage more negative than -4.00 V places the EFL in half-quiet mode. The up channels do not respond to changes in their inputs in half-quiet mode. A voltage greater than +3.75 V and less than +5.0 V places the EFL in quiet mode. In quiet mode, the up and down channels do not respond Note: If a voltage > 0.8 V is applied to the mode pin, it must source less to changes in their inputs. than 400 μA. The voltage level at the mode pin must not exceed +5.0 V at any time. Please contact Advanced Energy® for an analysis of your requirements.
