YPS design, build and configure a range of high voltage e-beam power supply units (PSUs) to function with Field Emission (FE) based systems. The 30kV PSU is offered by YPS as a standard product. Please contact us to discuss requirements for 50kV and 100kV PSUs. PSUs are designed to endure high stability and ultra-low ripple, ensuring consistent operation. A PC-based interface connected via a fibre optic link provides remote control and high-speed monitoring for full integration into an FE-based system. The 16-bit DAC and ADC in the modules enable high resolution for control and monitoring.
