1 Function
1.1 Input voltage range
¡The range is from 85 VAC to 264 VAC or 120 VDC to 350 VDC.
¡In cases that conform with safety standard, input voltage range is
AC100-AC240V(50/60Hz).
¡AC input voltage must have a range from 85 VAC to 264 VAC for
normal operation. If the wrong input is applied, the unit will not
operate properly and/or may be damaged.
1.2 Inrush current limiting
¡Inrush current limiting is built-in.
¡If a switch is being used for input, ensure that it is configured to
handle the input inrush current.
¡A thyristor is used for protection from inrush current. When turning
the power OFF and then ON again within a short period of time,
inrush current limiting may be disabled; therefore ensure enough
time before switching ON.
1.3 Overcurrent protection
¡Overcurrent protection is built-in and comes into effect at over
101% of the peak current in. Overcurrent protection prevents the
unit from short circuit and overcurrent condition.
The unit automatically recovers when the fault condition is cleared.
¿Intermittent current characteristics
¡When the output voltage drops more than 50% of the rated output
voltage value at overcurrent, the average output current is re-
duced by intermittent operation of power supply.
1.4 Peakcurrent protection
¡Peakcurrent protection is built-in (The protection circuit operates
when load current exceeds the rating current and the use deviates
from the condition in Instruction Manual 4).
If this function comes into effect, the output is shut down (delayed
shut down).
The minimum interval of AC recycling for recovery is 3 to 4 min-
utes (*).
*The recovery time varies depending on the voltage and load at
the time the protection activated.
1.5 Thermal protection
¡Thermal protection circuit is built-in and shut down under following
condition.
1When the current and the temperature which exceed from the
derating curve.
2The case FAN stops or air flow is interrupted and the amount of
the wind decreases.
If the thermal protection activates, shut off input voltage, remove
the cause of the overheating, wait for the unit to cool down, and
recycle to recover output voltage.
1.6 Overvoltage protection
¡Overvoltage protection is built in. When the overvoltage protec-
tion activates, shut off input, wait for at least 3 to 4 minutes, and
recycle to recover output voltage(*).
*The recovery time varies depending on input voltage.
Remarks : Please avoid applying the over-rated voltage to the out-
put terminal. Power supply may operate incorrectly or fail. Incase
of operating a motor etc. , please install an external diode on the
output terminal to protect the unit.
1.7 Output voltage adjustment range
¡Adjustment of output voltage is possible by using potentiometer.
¡Output voltage is increased by turning potentiometer clockwise
and is decreased by turning potentiometer counterclockwise.
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.
If the unit is tested on the isolation between input & output and
output & FG, remote ON/OFF (option) must be shorted to outputs.
2 Assembling and
Installation Method
2.1 Installation method
¡When two or more power supplies are used side by side, position
them with proper intervals to allow enough air ventilation. Ambi-
ent temperature around each power supply should not exceed the
temperature range shown in derating curve.
¡Fix firmly, considering weight, though it can be used by the instal-
lation method shown in Fig.2.2.
2.2 Mounting screw
¡The screw should be inserted up to 6mm max from outside of the
power supply to keep a distance between inside parts and an iso-
lation (Fig.2.1).

3 Series Operation and
Parallel Operation
3.1 Series operation
¡Series operation is available by connecting the outputs of two or
more power supplies with the same output voltage, as shown be-
low. Output current in series connection should be lower than the
lowest rated current in each unit.
¡Parallel operation is show in Fig.3.1.
2.4 Expectancy life and warranty
¡Expectancy life
The expectancy life is as follows. The mean of load factor 100%
depends on installation condition, refer to SPECIFICATION.
¡Warranty
The warranty is 5 years when average ambient temperature of
year is Ta = 40Cor less and load factor is average 50% or less.
However, the warranty is 3 years when average ambient temper-
ature of year is Ta = 50Cor less and load factor is series 100%.
2.5 Current monitor
¡It is possible to monitor load current by measuring CB voltage that
is between CB terminal and -V terminal. The relation between CB
voltage and load current is shown in Figs.2.4 to 2.6.
Note : Figs.2.4 to 2.6 are references, and are not meant to be
taken as guaranteed values.
¡Ensure that voltage measurement between CB and -V terminals
is carried out with equipment that has sufficient input impedance
(testers, etc.). If this equipment has low input impedance, then the
relationship between CB voltage and output current will change.
Additionally, please be aware that a short between terminals may
result in damage to internal components.
¡Please use twist pair cable or shield cable between CB terminal
and -V terminal, or the operation may be mulfunction.
¡Please use an oscilloscope for pulse loads.
3.2 Parallel operation/master-slave operation
¡Parallel operation is available by connecting below.
¡As variance of output current drew from each power supply is
maximum 10%, the total output current must not exceed the value
determined by the following equation.
When the number of units in parallel operation increases, input
current increases at the same time. Adequate wiring design for
input circuitry is required, such as circuit pattern, wiring and cur-
rent capacity for equipment.
In parallel operation, the maximum operative number of units is 5.

-The difference from standard is shown Table 5.1.
¡Peak load is possible to draw as below.
¡Ensure that the device is used in accordance with the following
conditions, as failure to do so may result in damage to internal
components.
¡Due to the nature of a pulse load, a power supply may make a
sound (noise). If the unit is used in a quiet place, consult factory
for the load condition in advance.
1100 VAC convection
2100 VAC forced air
3200 VAC convection
4200 VAC forced air
5 Option
¡Output voltage in parallel operation is adjustable by using the po-
tentiometer of the “master” unit. Select one power supply to be
the master, and turn the potentiometer of the other, “slave” power
supplies, clockwise to the end. Then use the potentiometer of the
mater to adjust output voltage.
¡When the output current is less than 5 to 9% of rated output
current(ACIN200V at forced air), the output voltage fluctuates oc-
casionally. The minimum current is different depend on the model
and the number of parallel operation, so please consult us at any-
time.
¡In parallel operation, output voltage increases like stairs due to a
delay of the rise time of output voltage at turn on.

¡In the event of one power supply failing and ceasing output of
power, use of N+1 parallel redundancy means that output voltage
is guaranteed through a backup; therefore, the system can con-
tinue with normal operation.
However, please consider the following condition.
15% or less of the output voltage decrease when one power sup-
ply stops.
2Even if one or several power supplies stop, output current that
meets the following formula is required from the remaining nor-
mally operating power supplies.
In parallel operation, the maximum operative number of units is
5.
3Please detach or exchange the broke down power supply after
intercepting the input voltage (impossible hot swap).
4The broke down power supply is detached or exchanged, and
after output voltage of new one is adjusted alone, the power
supply should be connected load (your system).
*Parallel operation cannot be done with standard model.
-
The following electric specifications are different from standard
model.
5If diodes are used to configure a circuit to achieve even higher
reliability, use connections as in Fig. 5.9.
-
Please connect the diode with +V.
-
Please do not connect VB of the power supply mutually.
