Hi! I saw your question, and maybe this will help. I also have a Texas Star 100w amp, and this same power supply. Even though the nominal draw for your equipment is way below the rated amp flow of the power supply, when you key up, and the output on the amp is at max, you are drawing the limit of your power supply! Try running this setup at a lower linear output. You don't need the full 100 watts to get out! 60-80 watts is aplenty! You should start at a low output, and slowly increase the output(while keyed up), untill the power supply starts to complain.(buzzer/light). This is what your limit will be. The only other cure, is a MUCH bigger power supply. Unfortunately, I cannot afford a 60-90 amp supply, so this is what I am forced to do to use the one we have. Also,keep your cb's output very low when using the linear amp. These amps are supposed to get a low signal from your radio, or the linear amp is overdriven. (noisy and unstable. Hope this helps you! 73's to you! jimsjinx

Will the unit power up without the cb radio? I would suggest a short somewhere in the system if the protection light continues to shine bright.

Hello,

I don't think it is possible. That won't be a good idea. It's a bad idea.

Allowing the not too bright individual is like using the unit as a experiment. I think they cost too much money to be used as an experiment.

Also, situations may arise where the not too bright person won't be able to handle.

In conclusion, my answer is "It is not Possible".

I hope the above is clear. if not, please let me know.

Regards.

if the lead wires are disconnected then it might be shot. have you checked the fuse?

I found one at www.retrevo.com

Yes, you can use this as a battery charger, but you would have to manually disconnect the power supply every so often and check the voltage of the battery to see how charged it was. Once the battery was fully charged, you would need to disconnect it, so it would not become damaged by overcharging.

Note: I'm answering your post with the assumption that you plan on using this power supply with a computer. If this is not your intention, please disregard my solution attempt.

You likely already know this, but if you are powering a computer you're going to need a power supply with more wattage. I would recommend nothing less than a 350 watt power supply.

Follow this link to calculate how much power you need to run your computer: http://www.extreme.outervision.com/psucalculatorlite.jsp

If you're not ready to give up on your 270 watt power supply, then remove all PCI/PCI-E devices, USB ports, extra fans, non-boot hard drives, extra DVD/CD drives etc. one at a time until the computer powers up. Anything you can do to reduce the load on the power supply will help.

Good luck and thanks for using FixYa.

Hi jjmn2rcp,
Current is defined as voltage divided by resistance. By adding a load to the amp, you decrease the current. Normally the amp should compensate for this, but if the load is to high, the amp will shut down to prevent damage, which is likely what's happening in your case. The amp is rated for 13.8V DC at 10 amps, so make sure you don't have to much connected to the amp. You can find a manual and schematic for the amp at http://pyramidcaraudio.com/manuals/PS15KX.pdf.
Hope that helps!

Usually, this indicates an overload condition. I have a Pyramid 35 amp supply that has no green light but uit does have a red light and an irritating little beeper that the instruction book says is activiated when power draw approaches 90% of rated output. (Why not call it a 30 amp supply if you can't use the full 35???) Enough editorializing. You don't say if the supply actually works, just that the light changes color. If it doesn't work at all, I would start with checking the diode bridge for a blown or leaking diode. If one is bad, it can output enough to drive an LED but fail anything else. If these are good, check the filter capacitor. If this is bad, the hum could concievably confuse the regulator circuit. Next, I would check what ever voltage regulator it has in it. I can't comment on specifics as there are many schemes that can be used. My unit, for example, is like a mouse driving an elephant. It has a small 723 regulator IC, (Aprox. 100ma output), controling 4 large TO-3 pass transistors driven by a 36 volt 40 amp transformer to boil it all down to an adjustable 12 to 15 volts.
The bottom line is without knowing if the unit is puting out or not and not having it in my hand to look at, this is the best I can do. I hope it helps.
Good luck.

Needs to get a Depot service done for the Electronic board. Could be an issue with Capacitor or IC. Good luck.

if this is on your computer

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ? hope this helps
