PBA100F, PBA150F, PBA300F, PBA600F,
PBA1000F and PBA1500F
¡Input
voltage range of the power supplies is from AC85V to
AC264V or DC (please see SPECIFICATIONS for details).
¡In
cases that conform with safety standard, 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 ac-
curacy might exceed the specification. Please contact us.
¿
PBA300F, PBA600F, PBA1000F, PBA1500F and
PBA1500T
¡You
can use a unit with an input voltage lower than AC85V and
DC120V (PBA1500T is AC170V 3f) by option (please see 7. Op-
tions). If you do so, load derating is necessary. Please contact us
for details.
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.
¿
PBA1500T
¡The
input voltage range is AC170-264V (three-phase).
¡In
cases that conform with safety standard, input voltage range is
AC200-AC240V (50/60Hz).
¡The
input phase line shall not be specified, it can be connected to
any input terminal.
¡In
the case of three-phase four-wire system, connect the three
wires to input terminal (L1, L2, L3), except ground wire.

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.

¡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.
¡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.
tion point is set depending on output voltage setting. However,
even if a sensing line makes open or external voltage is applied
to output terminal in order to activate the function at receiving
inspection, the tracking function does not work, so the function is
activated with higher value in a catalog.
Therefore, do not perform the function test to avoid the any trou-
ble.
¡The
follow type overvoltage circuit doesn’t operate when the
remote sensing comes off. In this case, a standard overvoltage
protection circuit operates. When the overvoltage protection circuit
operates due to the breakdown of the power supply, it is similar.
Standard overvoltage protection circuit is please contact us for de-
tails.
2.3 Overcurrent Protection
¡An
overcurrent protection circuit is built-in and activated at 105%
of the rated current or 101% of the peak current. A unit automati-
cally 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.
2.5 Thermal Protection
¿
PBA300F, PBA600F, PBA1000F, PBA1500F
and PBA1500T
¡A
thermal protection circuit is built-in.
The thermal protection circuit may be activated under following
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
fl
ow 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.
¿
PBA1000F, PBA1500F and PBA1500T
¡Output
Voltage Shutdown
If the overcurrent protection circuit operates continuously for 5
seconds, the output voltage will shut down. To recover the output
voltage, remove a condition that is causing an overcurrent, shut
down the input voltage, wait more than 3 minutes and turn on the
AC input again.
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.
2.6 Output Voltage Adjustment
¡To
increase an output voltage, turn a built-in potentiometer clock-
wise. To decrease the output voltage, turn it counterclockwise.
¿
PBA10F, PBA15F, PBW15F, PBA30F,
PBW30F, PBA50F, PBW50F, PBA75F,
PBA100F and PBA150F
¡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 7 Options).
¿
PBA600F, PBA1000F, PBA1500F and
PBA1500T
¡In
addition to a standard overvoltage protection circuit, an over-
voltage protection circuit to follow to output voltage is built-in. If an
output voltage exceeds a pre-set value, the overvoltage protection
circuit to follow to output voltage is activated and shut down the
output voltage.

The Overvoltage protection circuit to follow to output voltage is

PBA300F, PBA600F, PBA1000F, PBA1500F
and PBA1500T
¡The
power supplies have an external output voltage control func-
tion. The output voltage can be adjusted within a 110% range
from almost 0V by changing the voltage between the terminal
TRM and the terminal -S on CN1. You can decrease the voltage
by drawing a current from the TRM terminal.
You can calculate the output voltage in this case from formula
1
below.
Please note that the formula
1
gives you only an estimate.
Please contact us if you need accurate numbers.

optional for PBA300F.
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.
¡In
PBA600F, 1000F, PBA1500F and PBA1500T series, the over-
voltage protection circuit is a tracking method in which the detec-
