The range is from AC187V to AC528V single phase.
AC input voltage must have a range from AC187V to AC528V for
normal operation. If the wrong input is applied, the unit will not op-
erate properly and/or may be damaged.
lnrush current limiting is built-in.
In cases that conform with safety standard, input voltage range is
AC240-AC480V(50/60Hz).
If a switch on the input side is installed,it has to be the one han-
dling the input inrush current.
The thermistor is used for protection from inrush current. When
power is turned ON/OFF repeatedly within a short period of time,it
is necessary to have enough time for power supply to cool down.

Overcurrent protection is built-in and comes into effect at over
105% of the rated current.
Overcurrent protection prevents the unit from short-circuit, overcurrent,
or peak current exceeding the specified range.
The unit automatically recovers when the fault condition is cleared.
Peak current protection is built into FCA200F.
When the power supply is operated at as folloows, this function
comes into effect and shut down the output.
Continuous over rated current.
Over peakload based on 2.8 peak current.
Output shall resume about 120 seconds after power is turned off.
Thermal protection is built into FCA200F.
When the power supply is operated at as follws, this function co-
mes into effect and shut down the output.
Over rated temperature.
Poor ventilation.
Continuous over rated current.
Over peakload based on 2.8 peak current.
Turn off power and drop the temperature to normal level.
Output shall resume after applying input voltage.
Overvoltage protection is built-in and comes into effect at 115 -
140% of the rated voltage.
The AC input should be shut down if overvoltage protection is in
operation.
Please avoid applying the over-rated voltage to the output termi-
nal. Power supply may operate incorrectly or fail.In case of oper-
ating a motor etc. , please install an external diode on the output
terminal to protect the unit.
Adjustment of output voltage is possible by using potentiometer.
Output voltage is increased by turning potentiometer clockwise
and is decreased by turning potentiometer counterclockwise.
2.4 Peak current protection
2.5 Thermal protection
The minimum interval ofAC recycling for recovery is 2 to 3 minutes.
The recovery time varies depending on input voltage and load dur-
ing operation.

When two or more power supplies are used side by side, position
them with proper intervals to allow enough air ventilation. Ambient
temperature arround each power supply should not exceed the
temperature range shown in derating curve.
When cooling by forced air, arrange the fan so that ventilation can
be fully obtained inside the power unit.
Option with DIN rail attachment(option symbol:-N1) is only for
mounting A. Otherwise, vibration and shock will make the power
unit come off, which is dangerous.

n

Series operation is available by connecting the outputs of two or
more power supplies with the same output voltage,as shown below.
Output current in series connection should be lower than the low-
est rated current in each unit.
Parallel operation is not possible.
2.8 Isolation
nFor 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 out-
put & FG, remote ON/OFF (option) must be shorted to outputs.

Avoid the use except under the following conditions, or failure of
internal elements may be caused.
Because of the characteristic of load(pulse load), noise may be
generated from the power unit. Prior to use in the quiet location,
checking is required.
