The 2591P precision high voltage power supply is specifically designed for focused ion and electron beams. It is used in systems in which low noise, high stability and fast response are main requirements, such as electron and ion beam optics systems for integrated circuit fabrication and testing. The 2591P model provides very high quality output voltage parameters without sacrificing its reliability, since it can withstand severe short circuits, arcs and any other fast transients.

Over voltage and over current limits provide safe and reliable power supply protection against long-term overloads and load malfunctions. Implementing differential programming input as well as separating control return from case ground and high voltage return makes it possible that no noise from control inputs is reflected on the output side. These design features assure that the output ripple and noise specifications are always met.
