Power supply for Belkin router?

Turkey Machine · 11-12-2008, 11:13

After switching the routers in our house to combat the "having to reset it daily", we've come to the conclusion that the PSU for our Belkin F5D9230-4 is not the supplied one! (PSU supplies 1.2A @ 12V, the unit takes 12V at 0.5A from memory.) So can anyone point me to the correct PSU as Google isn't coming up trumps this time round.

I'd stick with the larger capacity one as it's then only running at 40% capacity. This means that there's less chance of overheating and burning out the windings...

As long as the voltage is the same and the polarity is the same the amperage figure isn't really crucial as long as the power supply figure is equal too or higher than the actual current figure for the unit...

Be careful with that advise, since if its an unregulated supply it may only be 12v at the rated current, or a much higher voltage at a lower current. This could also cause stability problems or it could burn the router out altogether.

Extremely doubtfull as the board on the router will be regulated itself

Also whoever said that the PSU was unregulated

I seriously doubt it will be regulated on the board. And I said this "incase" the PSU was not regulated. I have a 12v battery charger and a 12v PSU for a network switch that open circuit is 19v

You have to be careful.

Sorry but after doing component level repairs on PC, printer and peripherals I've not yet seen a router, switch, hub, print server or any other modern day digital electronics board without either a regulated PSU or in 99% of cases regulation on the board...

Yes I agree that a 12v PSU that is unregulated will be somewhere i the region of 17-19v unloaded but with routers that's fairly irrelavant due to the regulation on the board (the processor and memory on the board will need a regulated 5 and 3.3v as well as the other IC's... If the board isn;t regulated how do they get that from a 12v supply????)

I was referring unregulated 12vDC being regulated to 12vDC not being included on the board, not the processor voltage requirements. While I have no qualifications in electronics, as you say, yes, its unlikely to be unregulated or it would have a regulator on the board, but for a Ã‚Â£30+ router, would you risk using a bad power supply and end up killing it?

Anyway, no point in arguing, its petty

Just make sure you use a decent regulated power supply and not some cheap unregulated one or you could risk damaging it... Thats the only point I was trying to make

You'd be perfectly right on some equipment but it is very dependant on the equipment, but modern day home/soho routers don't make use of anything above 5V on the main boards (the signal voltage is only between 2.2 and 2.8v)... the only ones that do use 12v would be something like a cisco with built in drive or serial connections and on them you would either find a regulated seperate 12v supply or an unregulated 14-18v supply...or even an internal multi voltage psu (switch or transfromer based..)

Anyway I'd personally keep the 1.2A psu the OP has but in the end it's upto them, if they don't feel safe about it no info I can give will stop them from wanting an original PSU, in that case there's absolutely no harm in either swapping or keeping..their choice

I should actually point out that the adapter is identical to the one I have for the Ambit 256 modem. Quite why it's being used as one for the router is a mystery to me!

Another point to mention, it's not 12V at 1.2A, it's actually 10V at 1.2A going to the router, which takes 12V at 0.5A. Is that safe or asking for trouble?

its a belkin get another make

Helpful.

Anybody?

I should add it's not gonna be made wireless, so that's one mitigating factor quashed.

you nay have to contact them. Years ago I had a US Robotics wired router, which started being temperemental, I contacted USR who said it was the powersupply, I faxed them copy of the receipt as it was under guarantie still, and they sent a new one. None of the power supplies I had, even those with switches to choose the power would work with it.

th'engineer · 17-12-2008, 18:25

you can use a mains adapter providing its correct voltage and current on your belkin it should have pin configaration and voltage current required

the belkins i have had in the past have never been stable and always needed rebooting, hence my comments on belkin
