RUDI-EA2 is a novel, modular high voltage power supply for photoemission and other demanding research applications. The electronics features fully calibrated, independently operating modules utilising the very latest electronics and software technology. Voltage supplies are controlled by high precision 16-bit digital-to-analog converters with high linearity and extremely high temperature stability. Automatic low and high voltage range settings, as well as output polarity, are under full user control.
The combined high specifiation and system flexibility makes RUDI-EA2 the obvious choice for many analysis applications, where stable, high voltage supplies are required and can also be readily configured by the end user.
Each RUDI-EA2 unit is supplied with a comprehensive serial communication protocol description which can be easily implemented for individual control needs, thus removing the reliance on specific, often prohibitive supplier software.
As the demand for smarter, connected technologies increases, PREVAC provides the best in class electronic solutions. The electronic mainboard of the RUDI-EA2 system is a showcase for the best in active digital and analog electronic components currently on the market.
