Single ph to 3 ph Ramp conversion.

[Patrick Cox]

I am about to link an inverter to a ramp I bought from a 240/230v supply. In the control box which was wired for 415v , the transformer within has 400v 24v on a label can this be operated at a lower voltage to produce the same 24v system. I will post a pic if I can.

 

[Barnaby Stedman]

Whats your question - what does the 24v part of the control box do or what?

 

[Pete999]

Maybe it would have been advisable to have investigated the requirements before you purchase this equipment. just saying.

I am concerned, you are asking a basic question about a transformer but you are about to convert from 400v 3ph to 230v single phase using an inverter.
There are many pitfalls waiting for you and my worry is you don’t have a good enough knowledge of the control system.

 

[Patrick Cox]

I have had a lot of advice on going down this route and quite a few electricians have done this , the motor involved is 3 ph as discussed, and it can receive 220 to 415v , this can be done with an invertor , and the system contained at present and in the past uses a transformer to utilise sensor equipment that inhibits the ramp control should it be necessary.
I would have thought maybe someone had understood that, but maybe didn’t expand enough.

 

[James]

It’s a walk in the park for any experienced electrician that has been trained in machine control systems.
It will be over the heads of many sparks that only do domestic work.
Some industrial electricians can’t do this sort of panel conversion.
Please be careful who you choose to do this for you.
P.s. the transformer will have to be changed.

 

[Patrick Cox]

That’s great I thought that , yes There are quite a few around me locally that have done this , I am just jumping ahead so I can look one up somewhere. Thanks

Can I ask , moving on , I’m sure an electrician can answer this when he sees the system , but to gain knowledge up front , would the transformer be A.C. to DC 24v.
That question may seem out of my depth , but just looking for something ahead.

 

[Barnaby Stedman]

i thought u originally told us that it was a 3ph to single transformer
i think first you need to learn a bit about control circuits

I know what I said I maybe didn’t explain properly.
I have bought an inverter that works from a 230v single phase supply to a 3phase 230 v 3 phase supply on a motor to take either voltage from 220 - 415v . There is a transformer in it to control a sensor system based on 24v . I will need to change that , and that is what I’m asking , hope that clears everything up. I have grasped what I’m doing , but don’t worry , it’s being done properly by a qualified knowledgeable electrician . I am just trying to buy components to change upfront , it can be done !

 

[James]

It absolutely can be done, I wasn’t questioning that.
I am just trying to point out that this is out of the realms of many electricians.

It needs an engineer that understands
reconfiguring 3 phase multi voltage motors
Safety and interlock control best practice
Installing and configuring inverters

Thanks

NO. Transformers are AC devices. AC in, AC out.

 

[Patrick Cox]

Ah well they are switching transformers 230v A.C. to 24 AC sorry terminology!
