Applications: Mass Spectrometers, Electron Guns, Electron Gun Evaporators, X-Ray Tube Filaments, Power input & control at ground potential
These power supplies use the proven power oscillator from the standard & X-Ray filaments of up to 1.5 ohm (including cable resistance). The filaments can be isolated from ground by up to 30 kV, while power input & all controls remain at ground potential.
Higher isolation voltages are also possible. Please consult the factory for more details.
