Extending the Output Power
The U2722A/U2723A is equipped with three dedicated channels of up to 20 V and
120 mA per channel.
Series connections
To increase the output voltage, tie two or more of the outputs in series as shown
in Figure 2-13. This is to obtain a higher voltage than that available from a single
output. Series connected outputs can be operated with one load across the
connected outputs or with a separate load for each output.
When a series connection is used, the output voltage is the sum of the voltages of
the individual output. The current is the current of any one output. Each of the
individual outputs must be adjusted to obtain the total output voltage.

NOTE
– Ensure that the voltage (when source current) or the current (when source
voltage) is not clamped.
– Preferably, both are at the same current range.
