explained. If the fuse is incorrectly replaced, a fire may occur.
● Changing the power supply voltage
The rated power supply voltage cannot be changed. Use the
product only at the rated power supply voltage indicated on the
product. Otherwise, a fire may occur. The product's rated power
supply voltage is from 100 to 240 VAC. Use the product in this
range. (For use at a voltage higher than 125 VAC, Please
confirm the voltage ratings of the power cord.)
■ Warning item on grounding
The product has the GND terminal on the panel surface to protect the
user from electric shock and protect the product. Be sure to ground
the product to safely use it.
II
USING THE PRODUCT SAFELY
WARNING
■ Warning item on installation environment
● Operating temperature
Use the product within the operating temperature indicated in the
rating column. If the product is used with the vents of the product
blocked or in high ambient temperatures, a fire may occur.
● Operating humidity
Use the product within the operating humidity indicated in the rating
column. Watch out for condensation by a sharp humidity change
such as transfer to a room with a different humidity. Also, do not
operate the product with wet hands. Otherwise, an electric shock
or fire may occur.
● Use in a gas
Use in and around a place where an inflammable or explosive gas
or steam is generated or stored may result in an explosion and fire.

that are indicated in the "Rating" or "Caution on use" column in the
instruction manual of the product. Otherwise, a product failure is caused.
Also, do not supply power to the output terminals from the outside.
Otherwise, a product failure is caused.
■ When the product is left unused for a long time
Be sure to remove the power plug from the outlet.
(Calibration)
Although the performance and specifications of the product are
checked under strict quality control during shipment from the factory,
they may aging rate because of aging rate in its parts. It is

1. GETTING STARTED
This chapter provides a brief overview of the LSG Series, the
package contents, instructions for first time use and an
introduction to the front panel, rear panel and GUI.
1-1. LSG Series Introduction
The LSG Series is a family of high performance DC electronic loads
positioned to test a wide range of different power sources. The DC
electronic loads are fully programmable to simulate anything from
basic static loads to complex dynamic loads. With the ability to
operate independently or in parallel, the LSG Series is extremely
robust and capable of molding to any test environment.
Please note that throughout this manual the term “LSG Series” refers
to any one of the models in the series lineup, unless specifically
stated otherwise.
1-1-1. Model Line Up
There are a total of 3 DC electronic load models and 1 booster
pack model.

Wire Gauge
considerations
Before connecting the unit to a power source,
the wire gauge must be taken into account.
Load wires must be large enough to resist
overheating when a short-circuit condition
occurs as well as to maintain a good regulation.
The size, polarity and length of a wire are all
factors in determining if a wire will withstand
short circuiting.
Wires that are selected must be large enough to
withstand a short circuit and limit voltage drops
to no more than 2V per wire. Use the table
below to help make a suitable selection.

Load Line
Inductance
Considerations
When using the LSG Series load generator,
voltage drop and voltage generated due to load
line inductance and current change must be
taken into account. Extreme changes in voltage
may exceed the minimum or maximum voltage
limits. Exceeding the maximum voltage limit
may damage the LSG Series.
To determine the voltage generated, the
following equation can be used.
E = L x (∆ I / ∆ T)
E= voltage generated
L=load line inductance
1-4-5. Load Wiring
14
∆ I= change of current (A)
∆ T= time (us)
Load line inductance (L) can be approximated
as 1uH per 1 meter of wire. (∆ I / ∆ T) is the slew
rate in A/us.

The diagram above shows how changes in
current can affect voltage.
Limiting Load
line inductance
Load line inductance can be reduced in two
ways.
1. Ensure load wires are as short as possible and
twist the positive and negative load wires
together.
2. Current change can be limited by limiting the
slew rate or response speed when switching in
CR and CC mode.
“Twisted pair” will be shown on any connection
diagram where the load wires should be twisted
together.

Description
The LSG Series has input terminals on both the
front and rear panels.
Follow the procedures below for all load
connections. Please adhere to the following
precautions to ensure your safety and to protect
the unit from damage.
Connection
When connecting the LSG Series to the DUT,
make sure that the polarity of the connection
between the DUT and the unit matches.
Ensure that the maximum input voltage is not
exceeded. The maximum input voltage is 150
volts.

Caution
If the polarity to the input terminals is reversed,
the reverse voltage protection function is tripped.
The reverse voltage protection function is tripped
when reverse voltages greater than -0.3V are
detected.
Warning
Do not touch any of the input terminals when the
unit is on.
Warning
Connecting the input terminals to the wrong
polarity can damage the DUT or the LSG Series.
Warning
The front panel and rear panel input terminals are
physically connected. Any voltage that is input to
one set of terminals will also appear on the other
set of terminals.
1-4-6. Load Wire Connections

Description
The front panel input terminals feature polaritydistinct caps and accept M6 sized crimped
terminals.
Caution
The front panel input terminals on the LSG
Series are physically connected to the rear
panel terminals.
Step
1. Turn the power off from the rear panel or put the
unit into standby mode.
2. Turn the power off from the DUT.
3. Connect the load wires to the input terminals:
Connect the positive (+) input terminal on the
load generator to the high potential output of
the DUT.
Connect the negative (-) input terminal to the
low potential output of the DUT.

Description
The rear panel input terminals accept up to M8sized crimped terminals. The rear terminals
come with a load input terminal cover for safety.
Caution
The front panel input terminals on the LSG
Series are physically connected to the rear
panel terminals.
Steps
1. Turn the power off from the rear panel or put the
unit into standby mode.
2. Turn the power off from the DUT.
3. Connect the load wires to the input terminals:
Connect the positive (+) input terminal on the
load generator to the high potential output of
the DUT.
Connect the negative (-) input terminal to the
low potential output of the DUT.

Description
The rear panel terminal cover should be used to
prevent electric shock. The rear panel terminal
covers should always be used when connecting a
load to the rear panel terminals. As the front panel
and rear panel terminals are physically connected,
the terminal cover should also be used as a safety
measure when a DUT is connected to the front
terminals
Caution
Ensure the power is off before making any
connections to the LSG Series.
