Input voltage range of the power supplies is from AC85-AC132V
or DC110-DC170V. In cases that conform with safety standard, in-
put voltage range isAC100-AC120V(50/60Hz).
AC input voltage must have a range 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.
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.
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.

nTo decrease the ripple voltage further, install an external capacitor
Co at output terminal as shown below.

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.
