Unfortunately, the manual doesn't list the specifications for the AC adapter you need. You can however, charge the Powerpack via the cigarette lighter in your car. (see p. 16 of the manual). Also, look at p. 23 of the manual.
The unit is only 200watt and the fuse cost about $2,Thats if there one built into it,
The replacement power supply is about $20-00 NZD
Probably 20minutes to fix (for a novice) depending on their skill level and tools available,
BEST ADVICE Replace it
Power is something you dont want to mess with because it can kill.
The power packs are replaceable but people arent.
Be very careful and dont mess with the power.
1 or 2 extra hdds and ram does not require much extra power and your coolmaster should do the job. But if you intend to use a newer graphic card you should check the requirenments for wattage at your new card manufacturer product specification webpage. I am pretty sure that almost all newer graphic cards require at least 500 watt to run without problem. My advise is to buy at least a 550 watt psu although i don't know what is your hardware. Try to post your hardware specs and calculate for each component (cpu wattage+graphics wattage +etc) your power supply need to be over 50 wattage. Hope that helped!
Unplug the PS-15KX 120V AC cord !! Then take cover off. DO NOT plug the AC cord in unless you are used to working around a lethal voltage and current !!!!!!!!!!
If you can use a Multimeter, then measure resistance across each pair of the 3 leads of the output transistors. You will probably find fractions of an ohm across a pair of leads. One or both may be shorted. NOTE: Do not ever measure resistance in a powered up circuit, kiss meter bye-bye and maybe burn you too.
By putting more robust transistors in this supply, you may not gain much reliability. The supply is rated at a continuous current draw, which is less than the intermittent current they advertise. Read the spec's of any power supply you get and look for continuous current ability.
There are several better transistors that will substitute for the 2N3055. You will need to look at a transistor substitution book and check specs. The internet is great for this. I used to use all kinds of data books, and still have them! But looking up info on-line is nice. Motorola has some that will fit and have higher current and voltage ratings,
Get someone who is a ham or geek if you aren't sure about sticking your fingers in the power supply.
Be Careful, Work Safe, it is a factor of longer life.
This is a fairly ordinary 200 Amp, 600 Volt IGBT. It might cost this much because they just aren't made anymore.
Unless you wanted this part for a specific reason that you didn't mention then I think you'd be better off buying some more modern 'bricks' with better performance.
I got five 600amp 1200volt IGBT's for $100 off ebay a few months ago.
An avenue of research that might be of interest to you would be SSTC or solid state telsa coils. Google searches will find you many SSTC sites with IGBT H bridge circuits and drivers basically doing the same thing as you are intending.
