The new configuration options of the HV Rack series allow customers to order floating channels and green meters, making the series effective in even more environments and applications. The new floating-channel option means customers can configure one to four of the output channels in a unit to float any 0 to 4 W through 20 W, 0 to 15 kV (or lower) UltraVolt power supply up to 15 kV. Original versions of the units did not allow for floating channels. The new versions allow for power supply stacking or for hot-deck configurations, which are commonly used in electron- and ion-beam systems. In addition, the new green meter option replaces the standard blue meters used for current monitoring yet maintains the quality of the HV Rack’s vivid digital displays. While both types of meters are designed for use in high-ambient-light conditions, the new green meters may be desirable in many environments, including cleanroom and semiconductor processing applications.
