Power Supply Overview; High Speed Power Supply - Keithley 2303 User Manual

1-4 Getting Started

Power supply overview

The power supply (shown in Figure 1-1) can output up to +15V at up to 3A or +9V at up to
5A. Voltage can be set in 1mV steps, and current limit can be set in 100µA steps. Maximum
power output is 45W. The power supply can also be used to sink current (up to 2A). As a sink
(current polarity is negative), the power supply is dissipating power rather than sourcing it (see
"Sink operation" for details).
