Setting the Outputs
Outputs connected together in series cannot be grouped
.
To program outputs connected in series, first program the current limit
of each output to the total desired current limit point. Then program the
voltage of each output so that the sum of both voltages equals the total
desired operating voltage. The simplest way to accomplish this is to
program each output to one half of the total desired operating voltage.
The operating mode of each output is determined by the output’s
programmed settings, operating point, and load condition. Because
these conditions may change during series operation, the front panel
status indicator will reflect these changes. This is normal. Momentary
status changes are also normal.
Specifications for outputs operating in series can be obtained from the
specifications for single outputs. Most specifications are expressed as a
constant or a percentage (or ppm) plus a constant. For series operation,
the percentage portion remains unchanged while constant portions or
any constants are changed as indicated.
All series specifications referring to voltage are twice the single output
specification except for programming resolution, which is the same as for a
All series specifications referring to current are the same as for a single output
except for CC load effect, CC load cross regulation, CC source effect, and CC
short term drift. These are twice the current programming accuracy (including
the percentage portion) at all operating points.
Load Transient

Load transient specifications are typically twice the single output.
