Setting the Impedance and AC Power Supply
The following procedure is common to the 61000-3-3 and 61000-3-11 standards.
1
Set the impedance.
See "Setting the Impedance" below.
2
Press the EXT CONT key.
The External Control display appears.
3
Press the F1 key to select AC Power Supply Control.
A sub-menu is displayed.
4
Press the F2 and F3 keys to set the output voltage and frequency
respectively.
Set the AC power supply voltage and frequency according to the rated power of the EUT.
5
Set OUTPUT of the AC power supply to ON.
OUTPUT of the AC power supply is set to ON. The lamp icon in the upper part of the
screen lights up.
When it is synchronized with the frequency of the AC power supply, the triangular wave
in the PLL icon in the upper part of the screen becomes still.
6
Press the F6 key to return.
7
Turn on the power to the EUT.
Setting the Impedance
61000-3-3
Set to the reference impedance. The Line Impedance Network can be used; for details on
how to select the impedance, refer to the Operation Manual of the Line Impedance Network.

●
When you declare the maximum permissible system impedance (Zmax) of the
power supply to be connected as the operating condition of the equipment
•
The voltage drop caused by the EUT is 3% to 5% of the voltage.
•
The ratio of the reactance component to the resistance component of the impedance is
0.5 to 0.75.

AC power supply
Check whether it is output correctly.
Wiring
Check whether the plug for the voltage-sensing terminal is set and
connected to the VOLTAGE SENSING terminal on the rear.
Frequency
The PLL lock frequency range is 45 Hz to 65 Hz.
