Pleasure Boat Toroidal Wiring

Roger,
I grabbed the transformer you suggested. I'm at a bit of a quandry on how to WIRE it up. I have taken close up and detailed pictures of the transformer with the hopes that you might be able to assist me.

One pair will be power in, one will be power out. I will send a PM.

actually it looks simpler than we thought. Basically it looks as if 120v IN will go to the 2 BLACK wires and the 24v OUT will go to the Pump...

I am unable to get the PDF, the link doesn't seem to work. That would make sense as the lower voltage has a higher resistance and bigger wire is needed.

I fixed the link please try now.

after yall figure it out, would someone mind PM'ing me and sharing the information. (just for future reference)

Also, a question for Roger,
Is this transformer equal to a 6100 or 6000? or possibly between??
thanks

David,

I have since found out this transformer is not correct as a twin secondary output transformer with inverse phase is required. This functions essentially like US 230V where two 115V lines are opposite phase and can be combined to double the voltage and seperated as needed for half the voltage and the positive of one line rides out on the negative of the other. It is complicated but I will continue my search for an aftermarket alternative. The required output to equal a 6100 is 20V * 2 and 60VA capacity. 24V is a bit stronger and really the maximum that could be used.

Roger would a air con transformer work?

Hi Ralph,

I assume you mean the low voltage supply for the thermostat and controls? I think they generally just use a standard coil, I could be wrong or maybe you are talking about a bigger commercial type system I am not familiar with.

This is roughly what is needed, but the output voltage is too high, 24V is really the maximum and 20V would be the ideal and it only needs a capacity of 60VA. Preferably also not in a raw unprotected form like this one. On the old 6100 the US one strictly speaking was 19V and the Euro one was 20V and this is because the old driver had a rectifier and converted it to DC feed for the pump and the pump got about 24V DC either way due to the Hz difference.

 

[dahenley]

roger, the one you showed says 24V "each" does that mean its a 48V, or its actually 24V and would work, but would be maxing out the pump?

and, if it would work, (and since this has nothing to do with Tunze and its strictly DIY, a cage/box could be constructed around it)
is there a resistor or something like that that could drop the Output V down 4v?

just curious. (Im just starting my Magnets' and Circuits class, so im still New/Lost on this. )

thanks

 

[dahenley]

hey roger, do you have time to look at this and see if this would allow you to use the transformer you mentioned?

The full understanding of the electronics is beyond me, but I do know portions of the board use 40V AC, portions use 20V AC and the pump gets about 24V DC and can take up to 32V DC but this is the maximum and should be avoided and 24V DC is a safety limit as after that you can get arcing and safety issues that are avoided below 24V, that is why cars always stuck to 24V or below even though 36 or 48V was more efficient (electric and hybrid cars being an obvious exception). Planes are 48V and the wiring is always a concern and very specially made and heavily insulated and protected. That link is correct, but I would caution that one wrong move could nick the coil and create a short. The preferred would be to find something readily available and I am sure they are out there.
