■ Warning on using the product
The warning items given below are to avoid danger to the user's body and life
and avoid the damage and deterioration of the product.
Use the product, observing the following warning and caution items.
■ Warning items on power supply
● Power supply voltage
As the rated power supply voltage of the product, the range from 100 to
240 VAC can be used without being switched.
● Power cord
Important: The attached power cord set can be used for this device
only.
● Protection fuse
If an input protection fuse is blown, the product does not operate. When the
fuse is blown, the user can replace it. However, replace it correctly, observing
the warning and caution items that are provided in the section of the
instruction manual where the fuse replacement is 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.

III
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. Do not
operate the product in such an environment.
Also, use in and around a place where a corrosive gas is generated or
spreading causes a serious damage to the product. Do not use the
product in such an environment.
● Do not let foreign matter in
Do not insert metal and flammable materials into the product from
its vent and spill water on it. Otherwise, an electric
shock and fire may occur.

IV
USING THE PRODUCT SAFELY
CAUTION
■ Input/output terminal
Maximum input to the input terminals is specified to prevent the product
from being damaged. Do not supply input, exceeding the specifications
that are indicated in the "Rating" or "Caution on use" column in the
instruction manualof 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 recommended to periodically
calibrate the product so that it is used with its performance and specifications
stable. For consultation about the product calibration, call the dealer or the
company or each sales office where you bought the product.
(Daily maintenance)
When you clean off the dirt of the product covers, panels, and knobs, avoid
solvents such as thinner and benzene. Otherwise, paint may peel off or the

To wipe off the covers, panels, and knobs, use a soft cloth with neutral
detergent in it. During cleaning, be careful that water, detergents, and other
foreign matters do not get into the product.
If a liquid or metal gets into the product, an electric shock and fire are caused.
During cleaning, remove the power cord plug from the outlet.

1. GETTING STARTED
This chapter provides a brief overview of the LSG-H Series, the package
contents, instructions for first time use and an introduction to the front panel,
rear panel and GUI.
1-1. LSG-H Series Introduction
The LSG-H 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-H Series is extremely robust and capable of molding to any test
environment.
Please note that throughout this manual the term “LSG-H 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.

IMON Out
I MON OUT
Current monitor BNC terminal: Output
connector used to monitor the current
by outputting a voltage.
An output voltage of 10V corresponds
to the full scale current for the H and
L ranges. 1V corresponds to the full
scale current in the M range.
VMON Out
VMON OUT
Voltage monitor BNC terminal:
Output connector used to monitor the
voltage by outputting a voltage.An
output voltage of 8V corresponds to
the full scale voltage.
TRIG OUT
TRIG OUT
Trigger out BNC terminal:
Outputs a pulse signal during
sequence or dynamic operation. The
trigger signal has a 4.5V output with a
pulse width of a least 2us and an
impedance of 500Ω.

Variable Resistor
The variable resistors are used to adjust the full scale
and offset setting for the input value of the external
control sources such as voltage or resistance.
Exhaust fan
The exhaust fan is used to expel the heat from the unit.
Please ensure there is at least 20cm distance between
any object and the fan.
