I recently bought one from Jaycar, stock code MP3075, it was $189.
13.8 V
Continuous 15 AMP
17AMP 50% duty cycle
20AMP surge

have a look on their site jaycar.com.au under power adaptors > powersupplies

i had a look at jaycar and im just woundering how many chargers could you put on that power supply?

thanks

AC

Well it depends what you are charging at.. if you are crazy and are charging at 8 amps.. you would probably put only one on it.. but if you charge at 5-6 amps like normal people, you could be able to put 2 on it.....
As for a lamp, why dont you go and get one that runs off normal 240V power from k-mart and then put a daylight globe in it?

Jaycar have some very good supplies, the best IMO is a small 15 amp i think it is with a couple of gauges on the front, i think it is mid 200 dollars.

You need roughly 6-7 amps per charger, 12-13 amp for 2 chargers, and 15-18 amp for three chargers.

Spend as much as you can afford, it is a one off purchase and will last many many years of use. Try and get a decent light one some of the basic jaycar ones are very very heavy.

AC

yes i have a dickhead electronics one..quite a heavy black box

HPI_P3

do they all have gauages at the front so that you can control the ammount of amps going into the chargers. because at the moment i only have one charger so i will only need 6-7 amps. and is there any other places where you can get power supplies other than jaycar.

AC

Yeah most of them have guages... you can buy psu's from most electronic stores.. like dicksmith

HPI_P3

PSU'S???? what are they. and how much are they?

I think it was an abbreviation for power supplies.

AC

psu stands for Power Supply Unit

ok thanks. i was talking to someone and he said that he has a computer power supply and he has fixed it up so it is safe . he said that he wouldnt run his expensive chargers off a shoty one, but he said this one is reliable. are computer supplys reliable if you fix them up?

AC

Hmm, well some are, some arent. At my local club (forrestville aka northside) most people are using the computer power supplies, and they seem to be alright. If they have been done PROPERLY they are alright. But beware of the bodgy ones.

HPI_P3

the guy that i was talking to today was gonna sell it to me at castlehill raceway for $50 do think that is a shoty one to sell for that.becasue i dont think that this guy would sell me a dud.

I was using the jaycar jaytech10amp psu for bout 2 years with no probs.. it is a bit heavy and large (compared to a poota psu) but it was very reliable and was capable of handling high currents than it was rated at, tho i wouldn't recommend doing that.

as for weight: generally speaking, better quality electronic gear will weigh more than equivilent less quality gear. in this case, a better power supply will have a larger heatsink and a very sturdy case. try comparing equivilent hi-fi units.. an akai unit will be significantly lighter than a sony or yamaha.

as Besercoe said above, it should be a one off purchase so get something that will cater for the future.
