Preface Preface Welcome Thank you for using a Keithley Instruments product. The Series 2200 Multichannel Programmable DC Power Supplies are flexible DC sources designed to power a wide range of applications. The model 2230-30-1 offers three power channels and the model 2220-30-1 provides two channels. The output channels on both models are independent and isolated, allowing you to power circuits with different references or polarities.
Specifications This section contains specifications for the Series 2200 Multichannel Programmable DC Power Supplies. All specifications are guaranteed unless noted as "typical."
