4.2.12 OUTPUT IMPEDANCE Menu [MX30-3Pi or MX45-3Pi Model in 3 phase mode only]
Figure 4-26: 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 MX35-3Pi.
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.
