Default Power Supply forum

Here's a forum that all you guys can use to talk about your power supplys and ask questions about power supplys and all the good stuff . I'll start if off with some questions about the Novak N-Power power supply.

I'm considering buying a pulsar charger and a novak n-power power supply for the winter season so I have two chargers so I can race two classes on one night if I want to. I want to be able to operate two chargers off of the one power supply, both charging at 6 amps (I will only have one DC only charger when I first got the pulsar, but I just want to have the option of running a second DC only charger off it at the same time). The n-power is rated at 10 amps, but it says it has a dual out put, so is that 10 amps per output, or is it 10 amps combined ?? Thanks for any input!

I'm almost positive that it is 10 amp for both (five each). If you're getting a power supply, you can't go wrong with a Bulldog, maybe a 20 if they make it. That way you can charge two packs at 6 amps a pop. Also, the N-Power is kinda noisy as the fan stays on all the time.

I think you have seen my power supply, but it's a Integy 14 amp supply. Has served me very well and I can use 2 chargers without a hickup. You can get them for around 100 bucks. Pulsar is a killer charger too.

2Tenths is right, the N-Power's rated output is a total number, not an amount per terminal. If you try to run 2 chargers each at 6 amps on an N-Power, you might burn it up(or make it shut down, whichever it would do when overloaded). But you can run one charger at 6 amps & the other at 4 without any problems.....

It's 10 amps total. You can draw 10 amps off one terminal, or split it 6 / 4, or any combination, but it's 10 amps for the whole unit, shared between two terminals.

I've had motors drawing around 11amps, and you can litterally hear the fan on the power supply slow down due to lack of amperage. Not something I suggest doing, but it's not going to poof if you draw it's max for a second or two.

I run both a T-35Stealth & A CE PitBull off my N-Power no problem. I just cant charge & run a motor at the same time. I usually end up drawing to much, and the PitBull stops it's charge due to lack of amperage. hehe..

If you guys want to talk about good power supplies then have you seen the duracomm ones? They're really small and go up to a 25 amp model. www.speedworldraceway.com is the distributor.

Yes, they do still sell them. Mine is running very strong and never has given me a problem since day one. Cheapest is to buy directly from them at http://www.rivergatedist.com/products.htm
They do not take credit cards though. www.towerhobbies.com is another good place to buy rivergate power supplys...it's where I got mine.

Post Power Supplies

Rivergate does not make their own power supplies. They are a distributor for different companies that maufacture them. Usually says the companies name on the face. My Rivergate was maufactured by Todd Engineering Sales Inc. Unfortunately they are out of business now. They were bought by aaps. You can purchase power supplies directly from them at a fairly good savings.

Hope this helps,

Later,

Im currently using a Radio Shack 13.8v 10amp Power Supply. I love it. But it does get pretty warm/hot. Is there a way I can mount a small fan on there?

BTW heres a pic:



There is a heatsink in the back but is that good enough for cooling?
