SPECIFICATIONS

The programmable Keithley 248 High Voltage Supply offers reversible polarity, excellent regulation, low output voltage ripple, and flexible operation. Two front panel digital displays provide accurate readings of voltage and current output. A separate display simplifies setting output values precisely. The Model 248's output can be set using the front panel controls, over the standard GPIB interface, or via a remote analog voltage.

A source with low output ripple is crucial when using sensitive measurement instruments to characterize high resistance or resistivity. When operated without a filter, the Model 248 is capable of sourcing up to ±5000V DC at a maximum output current of 5mA DC with an output ripple of <0.002%. Two selectable filters are available to reduce output ripple in order to optimize operation for lower noise by trading off longer rise and discharge times.

Applications of the Model 248 include high-voltage resistivity and resistance testing, insulation resistance testing, high-voltage component testing, monitoring breakdown effects, and I-V measurements. 
  • Source voltages up to 5kV, negative or positive polarity
  • Up to 5mA compliance current
  • Low output ripple for precision sourcing
  • Two selectable filters
  • GPIB programmable
  • Programmable voltage and current limits
  • Compact, half-rack design
