4.2.12 OUTPUT IMPEDANCE Menu [MX30-3Pi or MX45-3Pi Model in 3 phase mode only]
Figure 4-27: OUTPUT IMPEDANCE Menu
The MX30-3Pi and MX45-3Pi offers programmable output impedance in three-
phase mode of operation. This allows the user to simulate line impedance
conditions by programming resistive and inductive elements of the AC source’s
output impedance.
NOTE: No programmable impedance function is available in single
phase mode or on MX system configurations other than the
MX45-3Pi.
The OUTPUT IMPEDANCE menu can be accessed from MENU 3. The following
fields are available in this menu:
Entry Description
RESISTIVE Sets the resistive component of the output impedance.
(The lower limits for the resistive and inductive
components may vary on different AC source models
and are set as part of the source calibration.)
INDUCTIVE Sets the inductive component of the output impedance.
(The lower limits for the resistive and inductive
components may vary on different AC source models
and are set as part of the source calibration.)
SET MINIMUM Selecting this field and pressing the ENTER key sets
both impedance components to their minimum values.
This effectively turns the programmable impedance
function off.
NOTE: The Programmable Impedance function of the MX30-3Pi or
MX45-3Pi is mutually exclusive with the Automatic Voltage
Level Control (ALC) mode of operation. One must be turned off
the enable the other.
