The following figure shows the life expectancy of the fan (EVS600W)
The difference between the intake temperature and the exhaust temperature of the product at 100%.
EVS600W : 10

Measurement point of fan exhaust temperature
The noise to occur from fan
：
25dB~45dB (Reference value)
8. External Fuse Rating
Refer to the following fuse rating when selecting the external input fuse.
Surge current flows when input turn on. Use slowblow fuse or timelug fuse. Fastblow fuse can not be used.
Fuse rating is specified by inrush current value at input turn on.
Do not select the fuse according to actual input current (rms.) values.
EVS300W : 6.3A
EVS600W : 15A
9. Before concluding that the product is at fault…
Before concluding that the product is at fault, make the following checks.
(1)Check if the rated input voltage is connected.
(2)Check if the wiring of input and output is correct.
(3)Check if the wire size is not too thin.
(4)Check if the output voltage control (V.ADJ) is properly adjusted.
(5)Check if the output current and output power does not over specifications.
(6)Audible noise can be heard when input voltage waveform is not sinusoidal wave.
(7)Audible noise can be heard during DynamicLoad operation.
(8)The builtin fan speed is reduced or stopped at light load (about 5% or less of rated output current).
The builtin fan is stopped due to output shut down. (Such as OVP or ON/OFF control, etc.)
