1.1 Input Voltage Range
¡Input voltage range of the power supplies is from AC85V to
AC264V (please see SPECIFICATIONS for details).
¡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 specifications and/or start hunting 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
might exceed the specification. Please contact us.
¡When DC input voltage is applied, external DC fuse is required for
the protection. Please contact us about detail.
¿ PLA100F, PLA150F
¡Power factor correction circuit will be stopped at AC250Vin
or more. The operation is normal except decreasing the power
factor. Please contact us about detail.
¡Operation stop voltage is set at a lower value by output power de-
rating.
-Use Conditions Maximum output power
PLA100F 40W
PLA150F 60W
Input AC50V (DC70V)
Duty 1s/30s
*Please avoid using continuously for more than 1 second
under above conditions. Doing so may cause a failure.
¿ PLA300F, PLA600F
¡By using -U option, it is possible to operate at input voltage dip
condition that is lower than AC85V. Output derating is required
(Refer to 5. Option and Others). Please contact us for details.
1.2 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.
¿ PLA100F, PLA150F, PLA300F
¡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.
¿ PLA600F
¡Thyristor technique 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 the inrush current
limiting circuit becomes operative.
1 Function ¡When the switch of the input is turned on, the primary inrush cur-
rent and secondary inrush current will be generated because the
thyristor technique is used for the inrush current limiting circuit.
1.3 Overcurrent Protection
¡An overcurrent protection circuit is built-in and activated at 105%
of the rated current. An unit automatically recovers when a fault
condition is removed.
Please do not use a unit in short circuit and/or under an overcur-
rent condition.
¡Intermittent Operation Mode
When the overcurrent protection circuit is activated and the output
voltage drops to a certain extent, the output becomes intermittent
so that the average current will also decrease.
¡When used with overcurrent at start-up, power supply may not
start-up by Intermittent operation mode. See the characteristics
below. (PLA100F, PLA150F)

1.4 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.
Remarks :
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 contact us for details.
1.5 Thermal Protection
¿ PLA100F, PLA150F
¡PLA100F and PLA150F do not have thermal protection.
¿ PLA300F, PLA600F
¡A thermal protection circuit is built-in.
The thermal protection circuit may be activated under the follow-
ing conditions and shut down the output.
1
When a current and a temperature continue to exceed the val-
ues determined by the derating curve.
2
When a fan stops or air flow is blocked from the fan and weak-
ens.
If the thermal protection circuit is activated, shut off the input volt-
age and eliminate all the overheating conditions. To recover the
output voltage, have enough time to cool down the unit before
turning on the input voltage again.

2 Series Operation and
Parallel Operation
2.1 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 power supplies
that are serially connected. Please make sure that no current ex-
ceeding the rated current flows into a power supply.

Fig.1.3 Example of measuring output ripple and ripple noise
1.7 Output Voltage Adjustment
¡To increase an output voltage, turn a built-in potentiometer clock-
wise. To decrease the output voltage, turn it counterclockwise.
¡When output voltage is adjusted, it should be turned slowly.
¿ PLA300F, PLA600F
¡We are offering an Option -V, which doesn’t have a built-in poten-
tiometer but instead enables you to adjust the output voltage by
using an external potentiometer (please see 5 Option and Others).
1.8 Isolation
¡For a receiving inspection, such as Hi-Pot test, gradually increase
(decrease) the voltage for the start (shut down). Avoid using Hi-
Pot tester with the timer because it may generate voltage a few
times higher than the applied voltage, at ON/OFF of a timer.
1.9 Low Power Consumption
¿ PLA100F, PLA150F
¡Low power consumption function is built-in in PLA100F and PLA150F.
(No load power consumption: 1.5W typ)
¡In 0 to 30% load, switching power loss is reduced by burst operation.
By this function, ripple and ripple noise specification are changed.
¡Ripple and ripple noise are changed by used condition. Please con-
tact us about detail.

Table 5.10 LV alarm operating conditions
Alarm Output of alarm
LV
If the output voltage drops below
the rating, the alarm signal is out-
put from LV and LVG terminal.
Note : 1This becomes unstable
in the event of output
overcurrent (intermit-
tent overcurrent).
2The alarm signal is not
output for parallel op-
eration that does not
use OR diodes.
Open collector method
Good : Low
(0 - 0.8V, 10mA max)
Fail : High or Open
50V 10mA max
¡Parallel operation
In case of parallel operation, please make the following process.
1Before wiring, output voltage should be set to the required
voltage at first to each power supply. Each output voltage dif-
ferences must be less than 0.1V or 1% of the rated output volt-
age, whichever smaller.
2Please connect each wire refer to Fig.5.10. And please use
same length and same type wire to connect each load line.
3As variance of output current drew from each power supply is
maximum 15%, the total output current must not exceed the
value determined by the following equation.
The rated
current per unit
= X(Number of unit) X0.85
Output current in
parallel operation
* Please confirm that each output current is within the rated cur-
rent.
-
When the output voltage adjustment is required after wiring, retry
the above process from 1again.
-
When the number of units in parallel operation increases, input
current increases at the same time. Adequate wiring design for in-
put circuitry is required, such as circuit pattern, wiring and current
capacity for equipment.
-In parallel operation, the maximum operative number of units is 5.
-It is not possible to work as master and booster operation.

When the output current is less than 10% of rated output current,
the output voltage fluctuates occasionally. The minimum current
is different depending on the model and the number of parallel
operation. Please contact us.
-
When output cable is not same length from each power supplies,
output current value will not be balanced at each units. Please
set the cable length as same as possible.
¡Remote sensing
-These models have a built-in remote sensing function.
If you do not use the remote sensing function, you can short out
between +S and +M and between -S and -M on CN1.
When the power supplies are shipped from a factory, they come
with a dedicated harness (H-SN-31) being mounted on CN1. If
you do not use the remote sensing function, you can use the
power supplies as they are.
-Please see Fig.5.10 if you do not use the remote sensing function.
Please see Fig.5.11 if you use the remote sensing function.
-When you use the remote sensing function, please wire from +S
and -S on CN1. Harnesses are available for your purchase.
Please contact us for details.
When you use the remote sensing, please note the followings.
1Wire carefully. When a connection of a load line becomes loose
(due to such factors as loose screw), the load current flows to
the sensing line and internal circuits of the power supply may be
damaged.
2Use a sufficiently thick wire to connect between the power supply
and the load and keep the line drop at 0.3V or below.
3If the sensing line is long, connect C1 and R1.
4Use a twisted pair wire or a shielded wire as the sensing line.
5Do not draw the output current from +M, -M, +S or -S.
6When the remote sensing function is used, the output voltage of
the power supply may show an oscillating waveform or the output
voltage may dramatically fluctuate because of an impedance of
wiring and load conditions.
Please check and evaluate carefully before using the remote
sensing function.
If the output voltage becomes unstable, we suggest you to try the
followings.
- Remove the remote sensing line on the minus side and short
out between -S and -M.
- Connect C1, R1 and R2.
Please contact us for details.

5.2 Others
¡While turning on the electricity, and for a while after turning off,
please don’t touch the inside of a power supply because there are
some hot parts in that.
¡When a mass capacitor is connected with the output terminal
(load side), the output might become the stop or an unstable oper-
ation. Please contact us for details when you connect the capaci-
tor.
¡In case of input voltage stop at no load, output voltage is kept for
several minutes because of low power consumption. Please be
careful in maintenance, to avoid electrical shock.
¡In PLA300F and PLA600F, thermal protection will be activated by
internal fan stop. Please have the regularly maintenance for im-
proving reliability.
¡When these power supplies are connected to the input terminal in
parallel, the total capacitance between line and line becomes big.
Therefore, the electrical discharge resistance on the safety stan-
dard might become necessary.
Please contact us for details when safety standard is necessary at
multiple units usage.
