@irrelevant pauper do you really mean "valuation" - i.e. how much all your stuff is worth??

That said, I'm 100% certain that she knows what she's doing, just to wind up the elders. Of course she also plays the game with me, "grandad I can't reach!" indicating feminine products on the top shelf, which having examined same she has me put back in favour of her usual brand which is at eye level. I think she's been taking lessons from granny (my wife). Love her to bits!

Isn't English a wonderful language, often means whatever the listener wants to hear Meanwhile I have relatives (yes, I'm a Brit) who would fit the descriptions although I doubt they'd go the "paedo" route they are certainly rather racist (against any and all "foreigners"), luckily the Thai family love their girls (my granddaughters) so any comments fly over at flight-level 350 and climbing. Out in the 'burbs I get the opposite effect. It's the Thai's with the black looks when I go shopping with my 100% Thai granddaughter, she's 14, pretty and just getting "starter curves", unfortunately she likes to hold granddad's hand! Cue the black looks and mutterings from the locals.

Yeah, I thought you would have already checked, but ... Cycling lives down:- Thailand Extra Forums => Community Forums => Sports, Hobbies and Activities => Cycling in Thailand (did I say it was well hidden?).

I would immediately be looking at a sharp/protruding spoke end since it's always the same place. Moving to the (well hidden) Cycling Forum ????

We like to continue life as normal when the PEA has decided that we don't actually need power. So our baby 6kVA unit runs everything except the water heaters and big irrigation pumps. It even runs our two inverter A/Cs without blinking (12,000 and 24,000 BTU units).

I think I'd be pulling the whole thing out and going for a nice modern unit.

Edit the full stop off the link and you get this:-

Are the A/Cs inverter type or conventional? If we assume they are 18,000 BTU each then you are looking at something like a 6kVA genset if they are inverter, possibly double that (say 10kVA) if they are conventional (large startup surge). Could you survive on one A/C? What's your preferred fuel? Petrol gensets are cheaper than diesel but burn a more expensive fuel. I would certainly go for one of the "silent" types unless you are miles from anyone else, the open frame units are noisy! I'd also ensure they are electric start / stop so you can add an automatic transfer switch for seamless operation (going outside in the dark and the rain to start the beast gets old very rapidly). There are a lot of units on the market now that are "ATS ready" or come with an ATS ready to install. Installation isn't rocket science but you'll need a sparks unless you are competent DIYing electrics.

OK, listen very carefully, I shall say this only once - Fuses do NOT that's NOT provide over-voltage protection! Fuses provide over-current protection for the power supply and your wiring, they do not provide any protection whatsoever for your cameras, that is not why they are there. EDIT The closest thing we have to a wai seems to be this which is called "jap" (I know, I know).

How do you expect glass fuses to protect your cameras from over voltage? I'm really not sure what your objection is to the auto-resetting PTC fuses. As I noted in an earlier post you could use 2 or 3 of the outputs in parallel to drive the XVR the PTC fuses will ensure that the current is shared equally by the outputs , or you could replace one of the PTC fuses by a 2.5A one. SMPS's really don't tend to fail over-voltage, they tend to fail no-output.

Yeah ^^^, just checked on the website, the vehicle reg is no longer in the profile. It's a loooong time since we got ours, we were definitely cautioned not to move it between cars on pain of death.

Yeah, we signed up at one of the offices. Once you've got it working you can top-up online, certainly the SCB banking app has a specific EasyPass option so dead easy! You're not supposed to use one unit for multiple vehicles but our original unit is still registered to the pickup from 2005, never any issues.

From the minimal detail available I would suggest the beast really is intended to supply 18 "1A" cameras, it's got a decent heatsink, fan and a 30A relay. Item 7 in that list is confusing as heck, I completely understand your worries, and what is Item 9 on about? Something that it's important to understand is the purpose of the fuses. They provide over-current protection in case of a short in your wiring, without them the power supply would quite happily shove >20A down your Cat-5 which it won't like, causing heating and potentially a fire. The fuses provide no over-voltage protection, the voltage rating is simply the maximum voltage they are rated to operate at (look at your average 20mm glass fuse, 250V even on the 12V side of the supply). Having the fuses also means that a short in one camera supply would leave the others unaffected and operating. If the PSU fails in a way that bangs out 24V, farewell cameras. One would hope that the PSU is designed in a way that would prevent that (in reality they usually end up with the driver devices going pop resulting in zero output voltage).

72V is the maximum the fuses can withstand? I'm not sure of your thought processes here! If you want more than 10A then find a unit that can supply more than 10A. Why not employ a professional contractor to design and install your TV system??

Why replace something that is designed for the job? I'm sure the box you have will do the job you need just fine (no warranty implied or inferred). To be honest I really can't help thinking that you are over-thinking your problem. Even flat-out downhill with the wind behind them your 6 x 1A cameras and 1 x 2A XVR are only going to pull 8A (in reality they will likely be pulling rather less) so does it actually matter if your box can only supply 10A?

They are rated at 1.1A 72V max. https://m.littelfuse.com/~/media/electronics/datasheets/resettable_ptcs/littelfuse_ptc_72r_datasheet.pdf.pdf It's important to understand that these chaps are not actually fuses or breakers, they are current limiting devices (when they get hot their resistance increases thus limiting the current). If one output won't power your NVR there's nothing to stop you putting two (or even three) outputs in parallel, the PTCs will ensure that the current is shared equally.

Yeah, the round yellow chaps are PT "fuses". Rather than try to interpret the Chinglish spec. (which might make sense when we know what the fuses actually are) in the manual it's better to research the markings on the devices themselves. How are they marked, are they all the same?

1A is probably the max charging current, leave alone, it's working ????

Can't say by looking, if it switches over instantly (like I would expect) then it's evidently got some rather smarter electronics than the other unit which seems from the description to think about it for a while.
