2 Function
2.1 Input voltage range
n
The range is from AC85V to AC132V or DC110V to DC170V.

AC input voltage must have a range from AC85V to AC132V or
DC110V to DC170V for normal operation. If the wrong input is ap-
plied, the unit will not operate properly and/or may be damaged.
Inrush current limiting is built-in.
If a switch in the input side is installed, it has to be the one han-
dling the input inrush current.
If the unit is shut down, recycling AC line has to be done after
cooling down the unit since thermistor is used for the protection
from the inrush current.
The SCR 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 between power ON and OFF to
operate resistance circuit for inrush current.
In cases that conform with safety standard, input voltage range is
AC100-AC120V(50/60Hz).
