Re: Non EV LED Lighting PSU Question

I've been looking through RS. Some little ones there , 440-430-420-410-400 type input tappings with labelled 230 out. as opposed to the one I bought from ETE, single in single out 415 in 240 out. With the RS one gives the chance to connect to higher input windings so lowering the output voltage. Rat...

Re: Non EV LED Lighting PSU Question

If my mate that painted it had been happy with the original built in light system on the lathe, I'd not be doing this We bought it together 3 years ago. Saddle gearbox was shagged...so we stripped it and rebuilt it...But Dave, wanted to make it look shiny too...so he started stripping irreklant bit ...

Since the 240V socket is ring next to the 415V 3 phase socket I think I would have just cable tied a 240V flex to the 3 phase machine lead and plugged both into the wall :wink:
That is how it is at the moment, but was just trying to get it all running off one.

Re: Non EV LED Lighting PSU Question

Ah yes, nice idea
Thanks
Will try that when I get home
Should of thought of that myself, as an extension to my own thoughts. I was thinking I need to load it with a bulb or make sure to power in other stuff first

Got plenty power resistors kicking about

Re: Non EV LED Lighting PSU Question

Already have enough 240 volt outlets on the wall, That is how we currently do it. Just wanted to get it all running off of one single feed. Alternatively I could run a new 5 wire three phase supply, to bring a neutral to the machine as well to give direct 240. But was trying to do it with as little ...

Re: Non EV LED Lighting PSU Question

OK, so I ordered one of these.. https://www.ete.co.uk/product/transformer-415v-to-240v-25va-single-voltage/ and it arrived. Tested it out, but because it is a transformer and its no load voltage being higher until load is drawn ..it is useless for me....bugger. Its no load output is 267 volts. Stick...

Re: Non EV LED Lighting PSU Question

Have ordered a 100VA 380-240 transformer

Would have liked bigger, but want to fit in existing box if I can

Encoder is 18 VA
Looking up LED lighting strips and swan neck units now

Re: Non EV LED Lighting PSU Question

What do you get if you measure between 2 phases of the 3 phase supply? Between phases will be single phase. 400 volts. Was To get standard 240 volts I need the neutral line too. Think in USA your single phase might be across two phases of your 3 phase, but over here we need the neutral to get down ...

Re: Non EV LED Lighting PSU Question

It is 240 vac input

Have been looking at other transformers

https://www.ete.co.uk/wp-content/uploads/2016/10/WV.pdf

Think if I got a 380 In 240 out, I could then run any lights with a 12v Switched mode type supply, and run the Digital display too

Re: Non EV LED Lighting PSU Question

Sorry, absolute Max would be 3 amp, simply because it has a 3 amp fuse in its standard UK 3 pin plug. As you say, probably much much less.

Non EV LED Lighting PSU Question

Not EV related... except if you were to say that if my lathe had better lighting, my next hub motor axle might be more accurate ! 🤪 Ok, so I have a Colchester Triumph 2000 lathe. British mains 3phase power, The power socket and cable is 4 pin, being 3 phases plus Earth. No neutral. I cannot run a ne...

Re: Info on stripping a DNP Epoch freewheel

There are abundant cassettes available with 11t high gear-- probably most of them. But what you have isn't a cassette. It's a freewheel. Your wheel can only take one or the other, and most hub motors take freewheels. Ah well OK , I got it the wrong way around. So in that case, when I did that, how ...

Seem to remember that there was no other option at the time. Think it was that there were no other cassettes available with an 11 tooth . There was a shimano that was made but almost impossible to find, and if you could find New old Stock, they were selling for hundreds of dollars. The DNP was the o...

I'd probably wire the PAS to these.
+5v red
GND 6 to black
TA to the other one

Re: Adding PAS to EM3EV controller

I f you want to open your controller and look, you might be lucky... If it happens to be labelled PAS, then you'd need to solder a wire to that pad, and another from a 5 volt feed and another to ground Get it wrong and you will of course risk screwing the controller on that controller it was labelle...
