Input Voltage Selector Terminals
Short-circuit the terminals if the input is 100 to 120 VAC and open the terminals if the input is 200 to 230 VAC.

Output Indicator (DC ON: Green)
Lights while a Direct Current (DC) output is ON.
6
Output Voltage Adjuster (V. ADJ)
It is possible to increase or decrease the output voltage.

Protection-ON Alarm Indicator
(DC ON: Red)
The red indicator will be lit if the overvoltage (for a 600-W model) or overheat protection (for a 600-W model)
circuit is triggered. This indicator will also be lit when overload (for a 600-W model) is detected.
8
Selector of Parallel Operation
Set the selector to PARALLEL if the Units are in parallel operation.

Definition
MTBF stands for Mean Time Between Failures, which is calculated according to the probability of accidental device
failures, and indicates reliability of devices.
Therefore, it does not necessarily represent a life of the product.
Life expectancy
10 yrs. min.
Definition
The life expectancy indicates average operating hours under the ambient temperature of 40
°
C and a load rate of 50%.
Normally this is determined by the life expectancy of the built-in aluminum electrolytic capacitor.
