2 Functions
2.1 Input Voltage Range
¡
Input voltage range of the power supplies is from AC170V to
AC264V.
¡
In cases that conform with safety standard, input voltage range is
AC200-AC240V (50/60Hz).
¡
If input value doesn’t fall within above range, a unit may not oper-
ate in accordance with specifi cations 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 specifi cation. Please contact us.
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.
¡
Relay 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 limit-
ing 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
relay technique is used for the inrush current limiting circuit.
2.3 Overcurrent Protection
¡
An overcurrent protection circuit is built-in and activated at 105%
- 120% of the rated current. A 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.
¡
Low-voltage protection is activated when output voltage is re-
duced by over current protection under the low-voltage protection
value.
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 10 or
more seconds and turn on the AC input again to recover the out-
put voltage.
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.
2.5 Low-voltage Protection
¡
Low-voltage protection is built-in. This protection will shut down
the output with the activation. To restart the output, recycle AC
input after 10 or more seconds.
