2.1 Input Voltage Range
¡Input voltage range of the power supplies is from AC85V to
AC264V.
¡To comply with safety standards, input voltage range is AC100-
AC240V (50/60Hz).
¡If input value doesn’t fall within above range, a unit may not oper-
ate in accordance with specications and/or start hunting or oper-
ate protection circuit or fail.
If you need to apply a square waveform input voltage, which is
commonly used in UPS and inverters, please contact us.
¡When the input voltage changes suddenly, the output voltage
accuracy might exceed the specication. Please contact us.
¡When the power supply is used with DC voltage input, an external
DC fuse is required for protection. Consult us for more details.
¡If the input voltage is more than AC250V, power factor correction
does not work and the power factor deteriorates. Consult us for
more details. (except KLEA240F, KLNA240F)
¡Operation stop voltage is set at a lower value than of a standard
version (derating is needed).
-Use Conditions
Output
KLEA120F,KLNA120F 70W

Input AC50V or DC70V
Duty 1s/30s
*Please avoid using continuously for more than 1 second under
above conditions. Doing so may cause a failure.
2.2 Inrush Current Limiting
¡An inrush current limiting circuit is built-in.
¡If you need to use a switch on the input side, please select one
that can withstand an input inrush current.
¡Thermistor is used in the inrush current limiting circuit. When you
turn the power ON/OFF repeatedly within a short period of time,
please have enough intervals so that a power supply cools down
before being turned on.
2.3 Overcurrent Protection
¡A overcurrent protection circuit is built-in and activated over 105%
of the rated current. A unit automatically recovers when a fault
condition is removed. Please do not use a unit in short circuit and/
or under an overcurrent condition.
¡Hiccup Operation Mode (except KLEA240F, KLNA240F)
When the overcurrent protection circuit is activated and the output
voltage drops to a certain extent, the output becomes hiccup so
that the average current will also decrease.
2 Functions 2.4 Overvoltage Protection
¡An overvoltage protection circuit is built-in. If the overvoltage pro-
tection circuit is activated, shut down the input voltage, wait more
than 3 minutes and turn on the AC input again to recover the out-
put voltage. Recovery time varies depending on such factors as
input voltage value at the time of the operation.
Note :
Please avoid applying a voltage exceeding the rated voltage to an
output terminal. Doing so may cause a power supply to malfunc-
tion or fail. If you cannot avoid doing so, for example, if you need
to operate a motor, etc., please install an external diode on the
output terminal to protect the unit.
2.5 Output ripple and ripple noise
¡Output ripple noise may be inuenced by measurement environ-
ment, measuring method g 2.1 is recommended.

2.6 Output Voltage Adjustment Range
¡To increase an output voltage, turn a built-in potentiometer clock-
wise. To decrease the output voltage, turn it counterclockwise.
2.7 Isolation
¡When you run a Hi-Pot test as receiving inspection, gradually
increase the voltage to start. When you shut down, decrease the
voltage gradually by using a dial. Please avoid a Hi-Pot tester with
a timer because, when the timer is turned ON or OFF, it may gen-
erate a voltage a few times higher than the applied voltage.
2.8 Signal Output
Functions of LED indicators.
¡Functions of LED indicators and signal output in the form of are
shown below. Checking the presence/absence of voltage at the
output terminal of a power supply is possible.

3 Series/Parallel
Operation
3.1 Series Operation
¡You can use a power supply in series operation. The output cur-
rent in series operation should be lower than the rated current of a
power supply with the lowest rated current among the power sup-
plies that are serially connected. Please make sure that no current
exceeding the rated current ows into a power supply.

¡When you mount a power supply on a DIN rail, have the area
marked A catch one side of the rail and push the unit to the direc-
tion of B. To remove the power supply from the rail, either push
down the area marked C or insert a tool such as driver to the area
marked D and pull the unit apart from the rail.
When you couldn’t remove the unit easily, push down the area
marked C while lightly pushing the unit to the direction of E.
