Keithley 2303 - Power Supply Overview; High Speed Power Supply

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).
NOTE Model 2303B has a blank front panel except for a POWER switch and an ON/OFF
LED. All references to front panel messages, menus, and keystrokes apply to the
Models 2303 and 2303-PJ, and the 2303B if using the Model 2304-DISP remote
display module.
