Pyramid 10 Amp Power Supply (068888701655) Power Supply Questions & Answers
Can I use this as a battery charger?
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.
The current drops when you put a load on it but
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!
The red lightcomes on when i hook up things to it
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.

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.
How did people at the bottom of the social pyramid support those at the top?
Well, look at the pyramid. There are more at the bottom... a lot more less powerful that hat to contribute and pay all to the owners of the land and we're allowed only to survive. In some cases, not even survive, slaves would be worked to ***** in many cases, in some civilizations under the farmers and artisans were thousands more slaves making the bottom of that pyramid wider, allowing for even more riches at the top.

How to resolve your meter when it's on temper mode
Tamper mode means the prepaid meter is in a mode where it does not supply power. Check your meter remote controller (used for recharging units). If it displays a Relay Open symbol, the meter is in tamper mode.
To remove tamper mode requires you contact the distributing company and request a tamper reset token. The tamper reset token is a 20-digit code that clears the meter from tamper mode and restores it to its default state.
My Employer Says They Are Going To Cut My Wages. Can They?
If you are in the middle of a contract, then cutting your wages is almost certainly a violation of your employment law rights. While I am by no means an expert on this matter, I did have a similar issue years ago - mid-contract wage cuts - and I hired an
employment attorney to fight the case on my behalf. It turned out that my employer was basically looking to scare people into taking the wage cut.
They got into some pretty serious legal trouble for their transgression, and nothing happened to me in terms of wage cuts after that. If you are between contracts, your employer can re-negotiate your salary, but as far as I am aware, if you are in an agreed-upon contract, they cannot just decide to reduce your salary. If you want to settle matters, contest this action with support from a legal professional.
