Hello there,

I've just received my 600W power supply from here:
24V 25A 600W Power Supply - Mega Power Hyperion Charger imax icharger | eBay

I'm trying to install it but I'm not sure if I'm right or not. Would need some expert confirmation on this as I don't want to put my house on fire lol.

I've found at home an UK plug with a 5 amps fuse. I've connected the L with the L of the power supply and the N with the N:




Is the connection right? Does the little thing in the middle of my plug the ground? Shall I plug that and it would work? no fire? lol

Hi You need to connect the Ground The Earth pin on the plug is the larger longer pin to the terminal next to the black mains connection very important or you may find the case off the power supply live with mains current and you need to insulate those live mains terminals in case somebody touches it by mistake

First of all, the "UK plug" in the photograph is an unusual type. In the common type of plug, the wires are connected by small screws, which I can not see in the photograph. The longest plug pin, as seen in the second photograph, is the earth, or ground , and normally would have a screw terminal , on the end of it inside the plug . I hope that the power supply itself has a cover for the terminals . Is there an earth terminal on the power supply? To wire it correctly to the mains you should use a three core cable, rather than separate wires, and there should be a clamp inside the power supply to stop the cable being accidentally pulled out. There should be a similar cable clamp inside the plug . I do not know what "that little thing in the middle of your plug" is. If there is no earth terminal on the power supply unit itself, you could connect the ground wire to the metal case . All appliances with metal case must have an earth connection.

Thanks Franck.

Added the insulation tape and wire to the ground of the UK plug:


Is it all right? Can I solder everything? :)

There is an earth terminal on the right of the main black one. I just wired it with another black wire. I also tested for continuity the little clamp in the middle and it's the ground.

Is it all right now? Am I safe to solder and plug it to my UK plug?

ps: The power supply is for 220V 50hz. I think it's fine for UK right?

The input voltage is stated as 220 to 240v so it covers the UK voltage range. Cwah, messing about with the mains is no laughing matter, its lethal plus if you cause a fire due to a wiring mistake you can bet any house hold insurance you may have will be void. Giving advise about batteries is one thing but mains wiring as you have it in the pictures makes me worry about your safety and any family you may have living with you. I wont advise you because I fear something is going to go wrong, the way you have wired the PSU is dangerous, very dangerous. Take the unit to a TV repair man and ask him to place it in an earthed box and to use double insulated wiring....

I need to use my power supply. What should I do except to ask for a TV repair man?? Can't I do anything?

What's so wrong about the picture?

yes BUT you still need someone to sort the power supply out, that bit needs a bit of work. I admire your enthusiasm, but you need to learn where to stop. Sorry did not mean to lecture but like NRG felt I had to say something :(

PS and empty your mail box :rolleyes:

Hi cwah

yes i would use a proper mains lead the plug you are trying to use is actually a euro 2 pin plug converter to uk 3 pin

As for other members comments I total agree don't play with mains it Lethal

I was trying to stop cwah using the psu without a safety earth as the case could end up live and also uncovered mains terminals

Guys, I'm going to use a real uk plug. going to take some picfure tonight.

It"s going to be too expensive if I ask for a professional.

will need your help tonight

CWAH - I'll take a pic of my Meanwell S-350-NES when I get home - it has connections like you have.

I used a kettle lead and stripped the ends and fitted them with ring terminals - have a look at the pic when I post it.

A TV repair man / workshop will be use to working with high voltages and as they are probable the easiest to find on the 'high street' it was the first though that entered my head when I saw the level of questions you where asking.

Its already been pointed out what is wrong with the wiring if you cant spot it then please seek some practical help. I'm all for self learning but there comes a point where a line needs to be drawn about giving encouragement over the internet...

Right cwah - get yourself a UK spec kettle lead, cut the kettle end off, strip back the wires and fit these:-



and properly heat shrink them. Advantage of ring terminals is they wont "pull out" of the connection block, leaving a live 240v cable to wave about.

Then connect them to your PSU as such:-



Don't rely on the cables being the right colour - you want to test them for continuity at the plug end (i.e. make sure the right pin goes to the wire you assume it goes to).

See if you can get hold of a termination block guard like mine has:-

I sense a forthcoming Darwin Award here...
"In the spirit of Charles Darwin, the Darwin Awards commemorate individuals who protect our gene pool by making the ultimate sacrifice of their own lives. Darwin Award winners eliminate themselves in an extraordinarily idiotic manner, thereby improving our species' chances of long-term survival."

Sad but probably true in this case.....Anyone who fools around with mains voltages without knowing what they are doing won't be about for much longer to carry on.

Guys, thanks for the safety warning. I'll take a maximum of precaution. Don't hesitate to warn me to the max in order to not burn my house.

Amifang, your advice and pictures are extremely precious, I did the same following what you've said:


I double shrink tape my wire and checked for continuity to make sure that the L goes with the L and same for all others.

I'm going to add 10 layer of insulation tape on top of all the wire (because I don't have the plastic cover).

And that should be fine?

I've been involved with some of Cwah's previous projects - full marks for enthusiasm (his, not mine) but he does worry me - and if you set yourself up to advise him, expect to make a big investment in time and effort.

Rog.

Rog, I'm very thankful for your help. It was really useful.

But you don't have to answer all my questions in details if it's too much. I'll also try not to ask too many questions and look for answer on my own.
