Ac+Dc Mode; Dc+Ac Mode - ITech IT7900P Series User Manual

5.3.3 AC+DC Mode

If the output mode select to AC+DC Mode, the instrument will simulate AC and
DC power supply, which can add DC component to AC voltage. Set the output
voltage in the main interface, as shown in the figure below.
Under AC+DC mode, Set the output voltage and frequency of the AC power
supply in the main interface, and set the DC voltage in the configure menu.
Vac: you can set the Vac under the main interface or under the config interface.
DC: set the DC component under the config interface. The setting range is 10%
of rated voltage.

5.3.4 DC+AC Mode

If the output mode select to DC+AC Mode, the instrument will simulate DC and
AC power supply, which can add AC component to DC voltage. Set the output
voltage in the main interface, as shown in the figure below.
NOTE
The AC + DC mode not only expands the application range of pure AC voltage, but also expands
the application range of DC component in laboratory testing.When using AC+DC for testing, please
first understand the ripple parameters of the instrument when it is used as a DC power supply. If
there are strict noise requirements, additional DC noise filters are needed to obtain low noise and
good stable DC voltage for testing.
