Really confused about umbilical cord connectors

jordyyy · 14th December 2010, 07:28 AM

I have two Antek 3225 (300VA 25V) transformers for my MyRevC amplifiers. Is there any connectors that will support both transformers on 1 umbilical cord? Would it be more reasonable to have two umbilical cords?

I found these: rated for 1500vac
Switchcraft - HPCP41F - Electrical Connectors - Connectors - Allied Electronics
Switchcraft - HPCC4F - Electrical Connectors - Connectors - Allied Electronics

xlr, neutrik, iec connectors are only rated for 250vac...

Does anyone have any suggestions? I went through a million searches and I'm having a lot of trouble. thanks

I suggest looking through this very forum, another thread just like this was begun and answered just last week

You are getting your volts and VAs confused. You are dealing with 110VAC in the US. The Netriks will do just fine and only one cord (I am asuming it is the power cord) will do.

tyco AMP connectors would handle the current and can be stacked.

What is/are the umbilical/s transferring? Low voltage or high voltage?

I think I might be way in over my head with the umbilical cord. I might switch my design to 2 single monoblocks and try and shield the transformers. Although, I was going to fit my lighter note kit into the amp chassis, I can separate that as well.

Mickeymoose: I think you are right.
If i used one Neutrik connector, it has 3 pins. Would that mean 4 reds would go to one pin, 4 blacks to another pin, and 2 green and 2 blues to the third pin? Should both the transformers be center taped or not?

If I could only see a picture of someone wiring two antek transformer up to an umbilical power cord I would be okay haha.

AndrewT: I don't know...

If you put both of your greens and both of your blues to the third pin you will be shorting out the transformer.

This frightens me.
Do alarm bells ring for anyone else?

Build two monoblocks. Copy exactly a good safe proved to work design and build example.
If you have any queries, post them before you start guessing.

Only way iv'e gotten this far. Im going with 2 monoblocks

On Antek xformers red and black are the two poles of your input to 110VAC
Blue and green are the outputs, 25VDC.
*normally* you would rectify the signal and add some smoothing to get DC before connecting to your amps.
If that is indeed the case then you will need three connections per monoblock, V+, V-, and GND.
If that's not how you're doing it then maybe a picture or drawing will help you explain what you're trying to do.
