ments. Also, with less than 3mV p-p noise, the power applied to the DUT’s load terminals is both
accurate and of high quality.
The maximum output power of 45W on the 30V channels and 30W on the 6V channel, combined
with voltage setting and reading resolution of 1mV and current setting and reading resolution of
1mA, generate a wide range of output power and read a wide range of load currents. Excellent
accuracy, remote sensing, and a wide power output range make the Series 2200 Multi-channel
Power Supplies a critical test instrument either on the bench or in a test system.
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 sup-
plies 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 perfor-
mance 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
The Series 2200 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.
• To save time when repeating tests, instrument settings can be saved in one of 30 internal memory
locations by simply pressing the Save button. To recall that setting, just push the Recall button, and
choose the desired setup.
