KS/KWS/KWD Series Instruction Manual
BEFORE USING THE POWER SUPPLY UNIT
● Check that input/output terminals are correctly connected
according to instruction manual.
● KWS/KWD series are designed for 85-265VAC continuous
input. No need to switch operation to 100VAC or 200VAC
input voltage.
● KS series is designed for 85-132VAC input. If a 200VAC is
input, the power supply unit will be damaged.

3. Explanation of Functions and Precautions
1 Over Current Protection (OCP)
6 Series/Parallel Operations
OCP type is current limiting with automatic recovery. OCP
For series operation, either (A) or (B) is possible. Please
function operates when the output current exceeds 105%
or above of OCP specifications. The output automatically recovers when the over current / shorted conditions
is removed. Do not operate under overload or dead short
conditions for more than 30 seconds, which could result
in damage to the unit.
connect a diode for by-pass when using method (A) of
the series operation. Please use the diode whose rated
forward current is equal or more than load current and the
rated maximum reverse voltage is higher than the output
voltage for each power supply.
3 Ripple
The maximum ripple voltage value in the specifications is
measured in the ripple measurement circuit designated by
JEITA RC-9131 probe. When the load wire is long, connect a film capacitor, etc., to prevent the ripple at the load
terminal from becoming large. Note that the accurate measurement is not possible if the probe ground lead of the
oscilloscope is long in measurement.

KWS
KWD
The over voltage protection (OVP) circuit with zener diode
clamp system is built in. (In KWD series, OVP circuit is
built into CH2 only.) Over 110% of nominal voltage will
clamp the output. If the output voltage is lowered due to
the over voltage application, the output will not resume.
Replacement of the power supply unit is necessary.

7 Isolation Test
KWS and KWD series are built to meet the VDE Class B
standards by adding external capacitor between L and N
on the input side.
Refer to the recommended values below.
KWS5, KWD5: AC250V 0.22μF
The insulation resistance between output and FG is more
than 100MΩ at 500VDC. For safety operation, voltage
setting of DC isolation tester must be done before the test.
Ensure that it is fully discharged after the test.

5 Inrush Current
KS10 and KS15 use power thermistor to protect the circuit
from inrush current. In power thermistor, the suppressed
current value changes depending on the temperature, and
the inrush current may become large in conditions with
high temperature or when restarting input soon after stopping it.

8 Withstand Voltage
This series is designed to withstand 2kVAC for between
input and output, 2kVAC between input and FG, and
500VAC between output and FG each for 1 minute. When
testing withstand voltage, set current limit or withstand
voltage test equipment at 20mA. (Output-FG: 100mA)

KS/KWS/KWD SERIES
The applied voltage must be gradually increased from zero
to testing value and then gradually decrease for shut down.

There is no restriction on mountintg direction but there
should be enough consideration for airflow so that heat
does not accumulate around the power module vicinity.
Also note that the output derating is necessary when the
ambient temperature is high, as shown in the figure in the
right.

5. Recommended soldering/cleaning
1 Recommended soldering medhod
2 Recommended cleaning conditions
The temperature conditions in soldering should be the following.
Recommended cleaning conditions after soldering are
shown below.
● Dip condition: 260℃, within 10 seconds
Pre-heat conditions: 110℃ for 30-40 seconds
● Soldering iron: 350℃ within 3 seconds
● Cleaning solvent
IPA (isopropyl alcohol)
● Cleaning procedure
Cleaning should be conducted with a method that does
not cause intrusion of the cleaning fluid into the inside of
the power supply unit. (Note that if the cleaning fluid intrudes into inside of the power supply unit, the reliability of
the power supply may be impaired.)
Note) Consult us if your cleaning method is other than that
recommended above.
6. Before concluding power module damage
Check if the rated input voltage is connected.
Check if the wiring of input and output are correct.
Check if the pattern width connected to input/output is
not too narrow.
Ensure that a large capacitor is not connected on the
output side.
Please use within maximum capacitance shown below.

5V 100μF or lower, 12V 200μF or lower
