Adjust Proper Line Voltage.
Insert proper rating Fuse.
Adjsut the Tap according
to required voltage.
Replace the Damaged Diodes.
Release the Remote Switch
in Normal Load Condition.
N
Is Device Drop setting proper on Load ?
N
Turn ON the Unit at Rated input Voltage. Load the Unit at
max rated Voltage and Current. Adjust the Voltage between
Output Positive and Capacitor Positive between
4.5V to 5V by using Please VR1 on PREG PCB

Check Line Voltage for 230V AC or 115V AC, whichever applicable.
Check whether Fuse Present is 20A for 115V AC I/P and 10A for 230VAC I/P.
Check the Transformer Tapping, whether it is configured accordingly to I/P
Line Voltage.
The Power Diodes connected in Bridge configuration on Heat sink might be
short.
If Remote Sense Switch is pressed on Load, in Normal Operation, there is
chance unit may take High Current and Fuse might Blow.
If Device Drop measured across O/P Positive and Capacitor Positive is not
between 4.5V to 5V at rated I/P Voltage and rated O/P Voltage and Load
condition, there is a chance of Fuse getting blow in Load Condition.
Note : 4.5V to 5V Device Drop at Full Load.
