5.18 Standard IEC Regulations
IT7900P series AC/DC power supplies provide standard test curves in
accordance with IEC 61000-4-11/4-13/4-14/4-17/4-28/4-29 regulations. It can
be invoked directly by the user when testing IEC compliance tests.
This function provides both the test curve that meets the standard requirements
of regulations and the curve customization function. Users can customize the
curve according to the project requirements of regulations and perform the
extended test of the test object.
The IEC 61000-4-11/4-13/4-14/4-28 regulation waveforms can be executed in
AC voltage source mode, the IEC 61000-4-17 regulation waveforms can be
executed in DC+AC voltage source mode, and the IEC 61000-4-29 regulation
curve can be executed in DC or DC+AC voltage source mode.
Click Standard on the Menu screen directly press Shift+
to enter the regulation test screen.
If in balance mode, the Phase Delay between the first instrument and the
second intrument is set to 60° to achieve six-phase balanced output of 60°
between six phases.
Light up the On/Off button of the second power supply, at this time the
second power supply does not output voltage and is waiting for the On/Off
synchronization signal from the first power supply, and when the first power
supply outputs On, the two units will output at the same time. This step
should be executed once before output. Otherwise the second unit cannot
turn on the output normally.
NOTE
For parameters of corresponding curves and related regulations, refer to
IEC standards.
