Over-voltage
protection function
(Input voltage)
The input voltage is 15.7 V or more (See: Graph
1).
The input voltage is 14.7 V or less.
Over-voltage
protection function
(Output terminal)
The output voltage is 180 V or more (See: Graph
2).
The output voltage is between 165-175 V or less.
Low voltage protection
function (Input
voltage)
The input voltage of 11.0 V or less continues for 2
s or more (See: Graph 3).
The input voltage is 12.0 V or more.
Excess-current
protection function
The input current is 12 A or more.
The input current of 12 A or less continues for 30 s
or more.
Electric power
protection function
The current is restricted if the electric power is
101 W or more. (Stops immediately if the current
restriction control continues for 10 s or more.)
Electric power of 100 W or less continues for 30 s
or more.
Overheating
protection function The inverter unit is overheated at between 100-
120 degree or more (See: Graph 4).
The unit temperature decreases by 5 to 15
degrees from when the overheating protection
function operates.
Output short-circuit
protection function
The AC output line is short circuited.
30 s or more has elapsed since the short circuit in
the AC output line has been repaired.
