2290-10 Keithley DC Power Supply

 Accessories Supplied:

• CD with user manual
• Software drivers
• Accessory information Power cord

 The Keithley 2290-10 provides voltage outputs up to 10,000V and has a 1mA current capacity. This supply measures both output voltage with 1V resolution and output current with 1µA resolution. In addition to the voltage and current output displays, a third display shows one of four settings: output voltage, voltage limit, current limit, or current trip. These values can be set precisely with the front panel keypad. The settings can also be programmed over the IEEE-4888 interface, or the output voltage can be set with an analog control voltage.

Low output noise is essential when using sensitive measurement instruments to make leakage current or high resistivity measurements. The maximum output ripple for the Model 2290-10 is less than 1V_RMS. The maximum output ripple of the Model 2290-5 is 100mV_RMS. Two selectable, internal filters on the Model 2290-5 reduce the maximum output ripple to only 3mV_RMS. Extremely low noise from both power supplies enables sensitive measurement instruments to make accurate current measurements down to picoamp levels.

Series 2290 Power Supplies and a Model 2290- PM-200 Protection Module protect both user and instrumentation from hazardous voltages. An interlock circuit built into the power supplies can be used to ensure that the output voltage is disabled if a high voltage test fixture access door is open. In addition, all Series 2290 power supplies have low voltage analog outputs to permit safe monitoring of the high voltage and the output current.
