9. The life expectancy
The life of the power supply depends on the life of the built­in aluminum electrolytic capacitor being used
and fan mounted products will depend on fan life. Each life is described in reliability data.
The life of the aluminum electrolytic capacitor varies depending on the method of mounting the power supply,
the load current, and the ambient temperature. Please refer to “Electrolytic Capacitor Lifetime”.
The life of the fan depends on the fan intake or exhaust temperature. Please refer to “Fan Life Expectancy.
Please do not use the product which passed over the life expectancy. There is a risk of unexpected output
shutdown and specifications may not be satisfied.
Please contact us for maintenance or exchange the product which passed over the life expectancy.
10. 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.
RWS1000B : 20A
RWS1500B : 30A
11. Before concluding that the unit is at fault…
Before concluding that the unit 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 Remote ON/OFF control connector is not opened, when use Remote ON/OFF control function
(/R, /RFO,/S).
(6) Check if the output current and output power does not over specifications.
(7) Audible noise can be heard when input voltage waveform is not sinusoidal wave.
(8) Audible noise can be heard during Dynamic­Load operation.
(9) Ensure that large capacitor is not connected on the output side.
Please use within maximum capacitance shown below.
Please contact us, if connecting more than the following capacitance value.
(10) The built­in fan speed is reduced or stop 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.)
(11) Check if the Remote sensing terminal is not opened.
12. Warranty Period
This product is warranted for a period of 5 years from the date of shipment.
For damages occurring at normal operation within this warranty period, repair is free of charge.
Please read the General Safety Instruction before using the products.
