2290-10 Specifications
10kV Voltage Power Supply Characteristics
CONDITIONS
This document contains specifications and supplemental information for the Model 2290-10
High Voltage Power Supply. Specifications are the standards against which the Model 2290-10 is
tested. Upon leaving the factory, the Model 2290-10 meets these specifications. Characteristics,
supplemental characteristics, and typical values are not warranted, apply at 23°C ±5°C, <70%
relative humidity, and are provided solely as useful information.
