6.2.5 Programming the Output Phase
You can control the phase of the AC voltage waveform relative to an external reference with:
PHASe <n>
which sets the phase in degrees. If <n> is positive, the voltage waveform leads the internal reference
or phase A value in three phase configuration.
Note: For three phase clock and lock configurations, the PHASe command sets the
relative phase of B and C with respect to phase A.
6.2.6 Current Limit
This command will set the rms current limit, to set this limit is:
CURRent <n>
where <n> is the rms current limit in amperes.
If the load attempts to draw more current than the programmed limit, and the source is set for constant
current mode, the output voltage is reduced to keep the rms current within the limit. Since the rms
detection involves a filter time constant that is long compared to a single output cycle, the response
time of the rms current limit is not instantaneous.
The power source can be programmed to turn off its output if the rms current limit is reached. This
protection feature is activated when the source mode is set for constant voltage mode.
Note: The CURRent command is coupled with the VOLTage:RANGe. This means that
the maximum current limit that can be programmed at a given time depends on
the voltage range setting in which the unit is presently operating. Refer to
"Coupled Commands" for more information.
