Flat screen TV 12 volt stabiliser

I ofter see people talk of running flat screen TV's on 12 volt.

hear is a stabiliser a bit pricey though

Try it

I think a lot of folks try it without the stabilizer
The price did not show up John!:Sad:

 

Press

Got it John
Press search and the price pops up!!!!!oh:oh:oh:

 

Just looked at my spelling in the original postingoh::Blush::Blush:

 

Your 12 volt battery is a natural stabilizer!
Don't believe all that crap about things blowing up!
There is not one recorded malfunction due to an un regulated power supply!

 

That'll be why the 240v supply unit is regulated and stabilized then !!!!!!!!!!

 

i bought one at york show and its the best thing i did :thumb:
over or under voltage and at best your tv will switch off but not with this supply.
you pay for quality.

I think what D.D. means that if you only run directly off the battery you are unlikely to have a problem. Surge or over voltage problems only arise when running the equipment and applying a charge, i.e. running engine or mains charger, at the same time.

I beg to differ. I've seen the result and seen the distress when the warranty claim was rejected. But then being in the business you tend to come across these things.
A secondary reason for using a voltage regulator is to avoid the tv dropping out everytime the heating kicks in or the water pump turned on.

Agreed there, it's a bitch having to switch on every time someone wants a pee, espescially when you drink as much bee, em cola as I do.

Also v handy for small chargers that need a regulated supply, you can get them with multi 'ends' now by the way although that was always easily overcome anyway.

 

Amperor often have them on eBay with a buy it price & make an offer. I got one for £36 with free postage. As said it keeps the voltage constant, another advantage I don't have to bother with the mains adapters for use when on hook up when the voltage is over 14 volts I just run everything off the 12 volt. I even made an adapter from a poundland 4 way cigarette adapter, I just plug the amperor into it & can run the TV, sat. digi box or freeview hard disk recorder off the it.

 

Your 12 volt battery is NOT a natural stabiliser at all, what it can do is act as a smoother to take out transient voltage pulses, not the same thing at all!

Having been "in the trade" for nine years, the last five in business for myself I can honestly say I've seen loads of domestic TVs buggered up by over voltage. The first ones I saw were about seven or eight years ago and were "Manhatten" branded and supposedly purpose designed for leisure vehicle use. I lost count of how many came back with burned out back lighting circuits due to over voltage and the manufacturers walked away form all of them as warranty claims.

I just picked one up for one of ours that is going to some festival in wales - he was running on a generator, so picked one up to smooth out any spikes. We had one blow on one of the hire vans last year due to this.

I think it was £36 with free overnight delivery from snellyvision.:thumb:

 

Mine was less than a tenner from Maplin, no doubt someone will say it cant be any good for a tenner.

 

I looked at the Maplins ones & if you read the info about it you will find that the 12 volts (which is what you want ) isn't controlled unless it's the input is 24 volts .
Have you checked it with the engine running to see what the voltage is?

 

The 12 volt adapter I bought from Maplin does regulate at 12volts (output current max 3A), so maybe they have changed to a different unit. Part code A92JH currently £19.99.

 

Have you checked the output with the engine running ?
Just read a question asking if it regulates the 12 volts & they say it does, but I'm sure I read on the pack that it doesn't for 12 volts but I hope I'm wrong.

 

Has any one ever had a TV damaged by running it direct from the battery? and I mean you directly not "I know a guy who had a brother whose son had one....."

Could this be just another urban myth started by the manufacturer of the gadget and of course there is always some one to buy one, then embellish it to justify his purchase.

Doug...

 

If you check the spec it is NOT a 24V input only 12v. It also states regullated accross all voltages.

 

Been running various tvs for 9 yrs wired direct into Ariel plug without a problem - pic goes off but leaves sound on giving plenty of warning of low battery :thumb:
