Got my Powerjack, LF 3000
It is fairly good, used it overnight seems to worked fine.
today, a fairly hot day I am having a issue of the system shutdown and buzzzzzz constant noise (a buzzer.. not an electrical buzz hahaha)
so i guess 1 of 2 things,
overvoltage or overheat
I have just set voltage to equalise at 15v and not shutting down.. must be undercoating
I have also noticed shutdown was at 14.6-14.7v max seems low?
anyways
I have a small switch on the rear and it makes fan stay on,
I have just switched the fan on and after close to an hour I turned it off after running fine for an hour..
EDIT: OK, It just turned off again!.. and I forced the fan on again and it has fairly warm air coming out, wouldn't call it hot!!
maybe they have a overtemp. set too low?!
My load is minimal.. like 200-300w
OK, so what can I do to solve this if I dont want the fan running 24/7
I can buy a small relay thermo switch on ebay for a few $$ and wire it up myself.. will be messy and adding of a small circuit.., I would rather fix it internally
can I fix this by changing anything inside? say a resistor?
