typical "outrush" NTCs in inverters?

[eccerr0r]

Anyone have a good idea what kind of resistance and energy handling I should target when subbing output NTCs on power inverters that have burned beyond a crisp?

Any good rule of thumbs anywhere?

My first inclination was to use something similar to inrush NTCs used on ATX PSUs and scale by the number of watts that it needs to handle...

Ahh pieced together one and it's TL10 010
20mm 10 ohm, 10 amp... oh this is going to suck to replace them all.
need to find a cheap replacement...

Speaking of these ntcs, What the heck??? How can you connect them in parallel?

btw, I should have mentioned these are kilowatt range DC to AC inverters, not for gas discharge tubes

Anyway I think I may have to make a substitution here...how it's currently designed is ridiculous.

By unpopular demand, carnage!


BTW I'm *this* close to just putting a jumper or fuse in the place of the NTCs...

(I ended up sticking in a lone 3 ohm 15A NTC temporarily after finding this power inverter is horribly designed - the case cannot be earth grounded!!!)
