Programmable DC Power Supplies
Great accuracy is not limited to voltage; the basic current setting and readback accuracy is 0.1%, pro-
viding high quality load current measurements. Also, with less than 3mV p-p noise, the power applied
to the DUT’s load terminals is both accurate and of high quality.
Excellent accuracy, remote sensing, and a wide power output range make the Series 2200 Multi-
Channel DC Power Supplies essential test instruments both on the bench and in test systems. Their
ability to generate a wide range of output power and measure a wide range of load currents is
supported with:
• Maximum output power of 45W on the 30V channels
• Maximum output power of 30W on the 6V channel
• Voltage setting and reading resolution of 1mV
• Current setting and reading resolution of 1mA
Configure the Channels to Double Output Voltage or
Current or Create Bipolar Power Supplies
The two 30V channels can be combined if more than 30V or more than 1.5A is required. The two
30V outputs can be wired in series to enable an output of 60V with a maximum current output of
1.5A or can be wired in parallel to get up to 3A at 30V. In series or parallel configurations, the power
supplies offer special display modes that indicate the actual voltage and current for the combined
pair. It’s also easy to wire the outputs to make a ±30V bipolar supply and to maintain a user-defined
ratio between the two outputs when using Tracking mode. These modes of operation extend the per-
formance of the power supplies, while the display shows the actual outputs in these special modes to
avoid any confusion or incorrect interpretation of the displayed data.
Convenience Features Help Get Results More Quickly
These multi-channel power supplies offer a number of features that return results quickly and easily:
• A rotary knob, with user-selectable step size, makes it easy to check circuit response to changing
voltage or current. Alternatively, a direct-entry numeric keypad can be used to simplify setting
precise voltage and current values.
• Each channel has its own readout on the display. The voltage and current being delivered to each
channel are visible at a glance. A bright vacuum fluorescent display provides excellent readability
at a distance, at an angle, or under dim lighting conditions.
