pure sine wave inverter

[McDisco]

Hey All

Anyone know where (apart from Fleabay) I can get a 150W Pure Sine Wave inverter for a good price?

Cheers

Jaycar electronics and Altronics phone numbers on the www at yellowpages.com

We use the Jaycar pure sine wave ones at work they seem to go OK

Jaycar MI-5080 is the cheapest I could see in the catalogues to hand at $180.

You will find pure sine wave inverters are a lot more expensive than the same power "modified sine wave", and are also less efficient and have a lower overload capacity.

Is that model from jaycar a pure sine wave? It needs to be a pure sine wave and I am running a brand new lappy that I dont think will take kindly to a MSW inverter...at least Im not prepared to risk it anyway....

I will only be using it for a single application at a time and such dont need to have a high wattage unit...its going to either run the laptop or be charging camera batteries.

what breed of laptop, jaycar also have a DC-dc switchmode powersupply that goes from 12v-most laptop power requirements.

I have their catalog and the altronics one so if you give me the type of laptop (and the numbers and specs on its powersupply will help) I'll give you the required part numbers for what you will need to make it all work in a rover.

They describe it as "pure Sine Wave" - They also have ones described as "Sine Wave" ($200 for 300w) and "modified sine wave" ($50 for 150w), so I would say that the one quoted (MI-580) is the one you want.

Yes, it is probably not very efficient transforming 13.8VDC up to 240VAC and then converting it back down again to around 15V DC or whatever your laptop runs on.

Nor particularly safe either!

Go the DC-DC converter....

We have a jaycar 150w pure sine wave inverter. I wanted a inverter to run my fish tanks (in the event of power failure). I tried all sorts of modified sine wave inverters and none of them would run them.

The jaycar inverter fires them up and they run quieter than on the mains :) I've not found anything since that it wouldn't charge/run either. :)

What's a bit of extra heat in the voltage conversion when the outside temp. is 40C as it was when I did the Simpson last year. I used the cheap Jaycar can shaped inverter and used it for my Uniden, SONY cameras and laptop all OK. When you have many different low DC voltage devices, an inverter is the easy way, just don't spill your beer on the inverter!:D

they are the suppliers to Jaycar etc....best to get an account though...

they are owned by jaycar and a couple of other electrical mobs.

our ausus laptop would not run on 150 watt we bench tested it in store 300 watt works great ;)
