High Voltage Power Supply Unit


YPS HIGH VOLTAGE POWER SUPPLY UNITS

YPS are able to design, build and configure a range of Power Supply Units (PSUs) to function with Field Emission (FE) based systems. The HV-PSU-30KV is offered by YPS as a standard product. 

FEATURES

Our PSUs are built for high performance with output voltages of up to 30 kV. PSUs are designed to endure high stability and ultra low ripple, ensuring consistent operation. The specially designed high voltage cable can handle up to 40kV with discharge management, whilst the vacuum interlock secures the FE system. Units are modularised for functions in field emission systems.

YPS PSUs provide high speed monitoring of the voltage and current supplies. A PC-based interface connected via a fibre optic link provides remote control and 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.
