Introduction
The DSI1020/ DSI3020 Dip Simulator is an option unit used to construct a test system complying with the
“Voltage Dips, Short Interruptions and Voltage Variations Immunity Tests” as defined in the IEC61000-4-11
Ed3.0 (2020) standard. It can be used in combination with one or more Kikusui AC power supply(ies)
(PCR-LE and PCR-WE).
The DSI meets the following test requirements: high-speed voltage switching (rise time: 1 μs to 5 μs), volt-
age dips (0 %, 40 %, 70 %, and 80 %), and phase-voltage and line-voltage tests.
Product features
Controlled from a PC software application
SD009-PCR-LE/WE is used to control a test system consisting of the DSI and one or more AC power
supplies that will perform “voltage dips, short interruptions and voltage variations immunity tests.”
Three types of communication interfaces (RS-232C/USB/GPIB)
The DSI is standard equipped with an RS-232C interface.
You can add a USB or GPIB1 interface as a factory option (P. 3). These options gives you flexibility in
constructing your test system.
Input voltage up to 500 V
The DSI3020 supports testing of 230 V three-phase four-wire, phase-voltage systems and 400 V line-
voltage systems.
Incorporation into a total test system
By combining the DSI with a Kikusui Harmonic/Flicker Analyzer (KHA series) and a line impedance
network (LIN series2), you can construct a total test system that fully complies with relevant IEC stan-
dards.
The next page shows an example of a three-phase four-wire test system comprising series of PCR-
LEs, LIN3020JF, KHA3000, and DSI3020.
1 GPIB interface is not supported with SD009-PCR-LE/WE (Ver.4 or later.)
2 PCR-WE cannot be combined with a standard line impedance network. For the line impedance
network for PCR-WE, contact your Kikusui distributor or agent.

Overview of the Test System
To actually perform tests using the DSI, you will need to install a test system that consists of the DSI and
one or more Kikusui AC power supply(ies.)
Voltage dips, short interruptions and voltage variations
immunity tests
AC power supply and firmware version
The following AC power supplies can be used.
Communication interface
The following communication interfaces can be used with SD009-PCR-LE/WE (Ver.4 or later).
Single-phase three-wire and three-phase output drivers (PCR-LE series only)
For single-phase three-wire output
Using two of PCR-LE series (U-phase unit and V-phase unit), install a single-phase three-wire output
driver (2P05-PCR-LE) in SLOT 1 of each unit.
Be sure to use the DSI in combination with Kikusui AC power supply(ies) (PCR-LE or PCR-
WE.) It cannot be combined with AC power supply(ies) made by other manufacturers.
AC power supply Firmware version
PCR-LE PCR-LE series The required firmware version of AC power
supply is different depending on the version
of SD009-PCR-LE/WE.
For details, see the setup guide of SD009-
PCR-LE/WE to be used.

Introduction
For three-phase three-wire or three-phase four-wire output
Using three of PCR-LE series (U-phase unit, V-phase unit, and W-phase unit), install a three-phase
output driver (3P05-PCR-LE) in SLOT 1 of each unit.
Sync signal interface
This is an interface for receiving sync signals output from the AC power supply.
When using PCR-LE, install the control board supplied with the DSI to SLOT 3 of the PCR-LE.
When using PCR-WE, use the REMOTE connector of the PCR-WE. The supplied control board is not
used.
Application software for controlling the test system
Use SD009-PCR-LE/WE to control the test system.
Use the cables supplied with the drivers to connect between the single-phase three-wire or
three-phase output driver connectors. For details, see the setup guide of the driver.

Installing the Test System
This chapter explains how to install a test system for “voltage dips, short interruptions and voltage varia-
tions immunity tests.”
DSI1020 Connection
Connecting the test circuit
Connect the DSI, the AC power supply, and the EUT to construct the test circuit.
1Check that the POWER switches of all devices are turned off ( ), and shut off the
power supply from the switchboard.
2Check that the terminal (protective conductor terminal) of each AC power sup-
ply’s INPUT terminal block is grounded.
3Unfasten the screws from the terminal cover attached to the lower part of the rear
panel of the DSI.
WARNING
Risk of electric shock.
• Be sure to attach the terminal cover of the DSI. High voltage will be applied to the ter-
minals.
• Before you connect cables to the AC power supply’ OUTPUT terminal block, be
sure to turn the POWER switch off, and then shut off the power supply from the
switchboard.
• Be sure to ground the DSI.
• Never connect the INPUT terminal block of the DSI to the AC line. The internal cir-
cuit of the DSI is not designed to be connected to the AC line.
• Fasten the terminal screws securely. Loose screws are dangerous because the
wires may come loose or the connection may heat up.
• The G terminal in the connect diagrams is not the protective conductor terminal (the main
ground terminal to be connected to an external protective conductor).
• The DSI does not include wires for connecting devices or crimping terminals for the
wires. Check the screw sizes of the I/O terminals of each device, and use appropriate
single-core wires and crimping terminals.
• We recommend that you use wires with a nominal cross-sectional area of at least 8 mm2
(AWG8).

Installing the Test System
4Connect the OUTPUT terminal blocks of the AC power supply to the INPUT terminal
block of the DSI using wires.
To connect to the OUTPUT terminal block of the AC power supply, see the setup guide of the AC
power supply that you using.
5Connect the OUTPUT terminal block of the DSI to the INPUT terminal block of the
EUT using wires.
If necessary, attach relay terminals between this product and the EUT.
6Attach the terminal cover that you removed in step 3.

DSI3020 Connection
Connecting the test circuit
Connect the DSI, the AC power supply(ies), and the EUT to construct the test circuit.
Four test circuits using the DSI3020.
•Test circuit 1: DSI3020 + PCR-LE/WE (1 unit) (P. 20)
•Test circuit 2: DSI3020 + PCR-LE series (2 units) (P. 21)
•Test circuit 3: DSI3020 + PCR-LE series (3 units) (P. 22)
•Test circuit 4: DSI3020 + PCR-LE2/PCR-WE2/PCE-WEA2 (1 unit) (P. 23)
1Check that the POWER switches of all devices are turned off ( ), and shut off the
power supply(ies) from the switchboard.
2Check that the terminal (protective conductor terminal) of each AC power sup-
ply’s INPUT terminal block is grounded.
3Unfasten the screws from the terminal cover attached to the lower part of the rear
panel of the DSI.
4Connect the OUTPUT terminal blocks of the AC power supplies to the INPUT termi-
nal block of the DSI using wires.
To connect to the OUTPUT terminal block(s) of the AC power supply(ies), see the setup guide of
the AC power supply that you using.
WARNING
Risk of electric shock.
• Be sure to attach the terminal cover of the DSI. High voltage will be applied to the ter-
minals.
• Before you connect cables to the AC power supply(ies)’ OUTPUT terminal
block(s), be sure to turn the POWER switch off, and then shut off the power supply
from the switchboard.
• Be sure to ground the DSI.
• Never connect the INPUT terminal block of the DSI to the AC line. The internal cir-
cuit of the DSI is not designed to be connected to the AC line.
• Fasten the terminal screws securely. Loose screws are dangerous because the
