1 Function
1.1 Input Voltage Range
The rated input voltage range of the power supply is AC85-264V
¡
(See SPECIFICATIONS for more details).
To comply with the safety standards, use the power supply with
¡
the input voltage range of AC100-240V (50/60Hz).
If the input voltage is outside the rated range, the power supply
¡
may not operate in accordance with the specications and/or start
hunting or fail.
If the input voltage changes suddenly, the output voltage may go
¡
out of the specications. Consult us for more details.
When the power supply is used with DC voltage input, an external
¡
DC fuse is required for protection. Consult us for more details.
PLA15F, PLA30F
¿
Power factor correction is not built-in. If multiple units are used in a
¡
same system, the input harmonic current standard may not be met.
Consult us more details.
PLA100F, PLA150F
¿
If the input voltage is more than AC250V, power factor correction
¡
does not work and the power factor deteriorates. Consult us for
more details.
PLA15F, PLA30F, PLA50F, PLA100F,

1.2 Inrush Current Limiting
¡
¡
Avoid using the power supply under the above-mentioned
*
conditions for more than 1 second continuously as the
power supply may be damaged.
PLA300F, PLA600F
The –U option is available for PLA300F and PLA600F to handle
instant voltage dip of less than AC85V but output power derating
is necessary. (See 5. Options and Others.)
Inrush current protection is built-in.
If you need to use a switch on the input side, select one that can
withstand an input inrush current.
Instruction Manual
PLA15F, PLA30F, PLA50F, PLA100F,

PLA150F, PLA300F
Thermistor is used in the inrush current limiting circuit. When you
¡
turn the power supply on and off repeatedly within a short period
of time, have enough intervals for the power supply to cool down
before being turned on again.
PLA600F
¿
Thyristor technique is used in the inrush current limiting circuit.
¡
When you turn the power supply on and off repeatedly within a
short period of time, have enough intervals for the inrush current
protection to become active.
There will be primary inrush current and secondary inrush current
¡
owing because thyristor and TRIAC technique is used for the in-
rush current limiting circuit.
1.3 Overcurrent Protection
Overcurrent protection is built-in. It works at more than 105% of
¡
the rated output current. The power supply recovers automatically
when the overcurrent condition is removed. Do not use the power
supply under a short-circuit or overcurrent condition.
Intermittent Operation Mode
¡
When overcurrent protection works and the output voltage drops,
the output voltage goes into intermittent mode so that the average
output current can decrease.
If the power supply is turned on with an overcurrent load, it will im-
¡
mediately go into intermittent mode and may not start up. See the
characteristics below. ( PLA15F, 30F, 50F, 100F, and 150F)

1.4 Overvoltage Protection
Overvoltage protection is built-in. If overvoltage protection works,
¡
shut down the input voltage, wait more than Table 1.1, and turn on
the input voltage again to recover the output voltage. The recovery
time varies depending on the input voltage, etc.

Avoid applying an overrated voltage to the output terminals as
it may cause the power supply to malfunction or fail. In case the
above-mentioned situation is expected in operating such loads as
a motor, for example, consult us for advice.

PLA15F, PLA30F, PLA50F, PLA100F, PLA150F
¿
These models are not equipped with thermal protection.
¡
PLA300F, PLA600F

Thermal protection is built-in.
¡
Thermal protection will work under the following conditions and
the power supply will shut down.
When the operating temperature and the output current greatly
1
exceed the derating curve.
When the built-in cooling fan stops or the air ow from the fan is
2
obstructed.
If thermal protection works, switch off the input voltage and elimi-
nate the conditions causing thermal protection to work. Allow
enough time for the unit to cool off before switching on the input
voltage again to recover the output voltage.

¡
ment. The measuring method shown in Fig. 1.2 is recommended.

Remarks :
When measuring output ripple or ripple noise with an oscilloscope,
do not let the oscilloscope’s GND cable cross the magnetic ux
from the power supply. Otherwise there may be electrical potential
generated on the GND cable and the measuring result may not be
accurate.

Load
PLA300F, PLA600F
¿
With the option –V, the power supply comes with an external po-
¡
tentiometer instead of a built-in potentiometer. (See 5 Options 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
PLA15F, PLA100F, PLA150F
¿
These power supplies are designed for low power consump-
¡
tion at no load. (No load power consumption: PLA15F:1.0W typ,
PLA100F/150F:1.5W typ)
When the load factor is 0 - 35% (PLA15F) and 0- 30% (PLA100F and
¡
PLA150F), the switching power loss is reduced by burst operation,
which will cause ripple and ripple noise to go beyond the specications.
Ripple and ripple noise during burst operation will change depending
¡
on the input voltage and the output current. Consult us for advice on
how to reduce ripple and ripple noise.
When there is a need to measure the stand-by power consumption,
¡
measure it by using the average mode of the tester. The measuring
environment may inuence the result. Consult us for more details.

the alarm signal will be
unstable.
The alarm signal won’t
2
be given in parallel
operation if OR diodes
are not used.
Parallel operation
¡
For parallel operation, please take the following steps:
1 (Before wiring) set the output voltage of each unit to the desired
value. The output voltage difference between the units must be
less than 0.1V or 1% of the rated output voltage, whichever is
smaller.
2 Wire the power supplies as shown in Fig. 5.10. Make sure the
output wires of the units connected in parallel are of the same
length and the same type.
3 Make sure the total output current does not exceed the value
determined by the following formula:
Output current in
parallel operation
The rated
= X (Number of unit) X0.85
current per unit
*Make sure the current drawn from each unit is less than the
rated output current.
When adjusting the output voltage after wiring, repeat the above-
-
mentioned steps (1 to 3).
If the number of units in parallel increases, the input current in-
-
creases as well. Make sure the input equipment and wires have
enough current capacity.
The maximum number of units for parallel connection is 5.

Master-Booster operation is not possible.

If the output current is less than 10% of the rated output current,
-
the output voltage may uctuate.
The required minimum current is different depending on the model
and the number of units in parallel. Consult us for more details.
If the length of the output wires of each unit is different, the output
-
current from each unit will be unbalanced. Make sure to use out-
put wires of the same length for all units in parallel.
Remote sensing
¡
These models are equipped with a remote sensing function.
-
If the remote sensing is not used, the following terminals of CN1
must be shorted:
+S and +M
–S and –M
When the power supply is shipped from our factory, a designated
harness (H-SN-31) is attached to CN1. If remote sensing is not
used, there is no need to remove the harness.
The wire connection when remote sensing is used or not used is
-
shown in Fig. 5.11 - Fig. 5.12.
When using remote sensing, make sure to nish wiring +S and
-
–S rst. The designated harness is available for sale. Contact us
for more details.
When using remote sensing, pay attention to the following:
-
Wiring must be done carefully. If there is bad connection on the
1
load lines due to loose screws, etc., the load current ows into
the sensing lines and the internal circuit of the power supply may
be damaged.
Make sure the wires between the load and the power supply are
2
thick enough to keep the line drop less than 0.3V.
If the sensing wires are long, place C1 and R1 across the load
3
lines.
Use a twisted pair wire or a shielded wire for the sensing lines.
4
Do not draw the output current from +M, –M, +S or –S.
5
The impedance of the wiring or the load may cause the output
6
voltage to oscillate or uctuate.
Test to conrm remote sensing works ne. If the output voltage is
found to be unstable, the following methods are recommended:
- Remove the remote sensing line on the minus side and short
–S and –M.
- Use C1, R1, and R2.

ter it is turned off.
If large capacitors are connected to the output terminals (load
¡
side), the output voltage may stop or become unstable. Consult us
for advice.
If the power supply is turned off at no load, the output voltage re-
¡
mains for a few minutes as the power supply is designed for low
internal power consumption. Be careful of electrical shock at the
time of maintenance.
If the built-in cooling fan in PLA300F/PLA600F stops, the built-
