2.1 Input voltage range

The range is from AC85V to AC132V or DC110V to DC170V.
AC input voltage must have a rage from AC85V to AC132V for
normal operation. If the wrong input is applied, the unit will not op-
erate properly and/or may be damaged.
In cases that conform with safety standard, input voltage range is
AC100-AC120V(50/60Hz).

Inrush current limiting is built-in.
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 and
overcurrent condition of less than 20 sec.
The unit automatically recovers when the fault condition is cleared.
The power supply which has a current foldback characteristics
may not start up when connected to nonlinear load such as lamp,
motor or constant current load. See the characteristics below.
Overvoltage protection circuit, clamping the output voltage by
zener diode, is built-in and comes into effect at over 115% of the
rated voltage. The unit in an overvoltage protection mode cannot
be recovered by a user; it must be repaired at the factory.
Overvoltage protection(diode)also comes into effect if the voltage
is externally applied to the output side.
Avoid applying voltage to the output side.
