7. External Fuse Rating
8. Before concluding that the unit is at fault, make the following checks.
MODEL
LS25
LS35~LS50
LS75~LS150
NOTE : It is normal to hear audible noise from power-supply under Dynamic Load operation or if the input voltage
waveform is not sinusoidal.
9. Warranty Condition
Warranty applies but not limited to the following.
Following cases are not covered by warranty.
Refer to the following fuse rating when selecting the external input fuse. Surge current flows when input turns on.
Fuse rating is specified by Inrush Current value at input turn on. Do not select the fuse according to input current (rms)
values under the actual load condition.
This product is under warranty for 3 years (based on 8 hours/day operation) from the date of shipment. During the
warranty period, TDK-Lambda will, at it’s option, either repair or replace products prove to be defective.
Check if the rated input voltage is connected.
Check if the wiring of input and output is correct.
Check if the wire size is correct.
Check if the output voltage trimmer (V.ADJ) is properly adjusted.
Check if the output current and output wattage does not exceed the specification.
Ensure that a large capacitor is not connected across the output terminals. Please use within maximum capacitance
shown below.
