Can anyone answer my question above?
So how does a dual regulated output work, since the power normally goes via the Receiver which provides a common power bus?
Thanks,
David

Don't have one, so can't give a definitive reply, but the simple method would be something like a Y-lead with the red (assuming Futaba) +ve lead removed from the plug that goes to the Rx servo output concerned.

That way the -ve is still common and the +ve second regulator voltage is taken from the Red +ve lead connected to the second regulator output via the other half of the Y-lead.

Out of interest, the common supply of voltage to servos is often changed on large scale models and jets where high servo currents often are most easily coped with by using a completely external -ve and +ve busbar and just connecting the -ve busbar to the Rx -ve to get the signal -ve reference point.

Hope this is of some help.

Basic explination I got...
Fromeco's new design is basically 2 regulators built into one unit.
There is a lead that provides voltage to the gyro at 5.0v and a second lead that provides 6.0v to the RX from the same supply pack. Which I assume would need to be about 7.2v to handle the dual load with surges and such, but that is an assumption.
Exactly how it does that is up to somebody with a big piece of paper hanging on the wall to explain.

Thanks guys, so one voltage output goes to the receiver while the other goes to the gyro, and the gyro +ve is isolated from the receiver...

In that case I see no reason why I can't power the receiver using the 5 volt output (601/9251 and 9252 cyclics etc), and drive my 9351 collective directly with the 6v output?

My understanding is that the new dual voltage regulator will provide 6V to all the servos except the gyro because some gyros cannot handle 6V. If both outputs are adjustable you can adjust the voltages as necessary.

Again, this is only my understanding. I don't have any product specific information yet....

Dr Lodge,

I think that will depend on the current rating of the two outputs. I'd guess that the 6V output will be the high current one and intended to run everything except the gyro/tail servo which will be run from the 5v output and be a lower current rating.

Only someone from Fromeco can tell us what the rated outputs of the two seperate regulators are going to be, but that would be my guess.

Thanks for your responses guys, think I may drop Fromeco an email to see if they can clarify its spec.

I presume its the 6V output that will be adjustable then?

Reply from mike@Fromeco
I got a reply from Mike at Fromeco, I hope he doesn't mind posting his reply in this public forum. Here it is:

~*~*~

We're not quite ready to release specs yet, I'll be writing up a cutsheet for the product as we wrap up the beta testing period, which may be quite soon.

The device will consist of two regulators on a common pcb, either of
which will be capable of driving the entire load on an all-digital ship (they are identical regulators). The design basis is assuming desert conditions (40C, radiative heat transfer) with minimal convection and substantially elevated temperatures inside a canopy (80C), which turns out to be quite conservative on several counts. I have not yet performed the specification run at STP, but at these most limiting conditions the regulator will quite easily handle 1.5A at 5V (gyro) + 4.5A at 6V (everything else).

[ My note - as both regulators are the same, I'm assuming I can run 1.5A at 6V (collective) + 4.5A at 5V (everything else) ]

The 5V portion is not adjustable, and is intended to provide power to
the gyro (it plugs into the regulator proper). The adjustable section will
have a range of roughly 4.9 to 6.2V, to the receiver.

[My note - need to wait to see how things connect in my desired config ]

I hope this helps a little bit; as I mentioned, we should be releasing
some sort of documentation within a couple of weeks.

~*~*~

So this is exactly what I need - two outputs, one @ 5V fixed, the other at 5-6V variable, and both can be used to power as much or as little of the radio gear as possible. My one reservation then is price compared to the single regulator product, we'll just have to wait for that.

I wonder if we'll see them sell their products via an outlet in the UK anytime soon...

Thanks Mike and Fromeco for your helpful respsonse.

I belive there is a good chance of that
(atleast I am waiting to try one, if they do come available)

On the way
My stock reg is on the way to them today.

When I get the new dual output I am going to put it through its paces. Well as hard as I can.
Then get with them on the results.
Hopefully this will help get the beta testing done and them on the market sooner.

I am really impressed with the quality of their stuff so if the new one is the same (I am sure it will be) then we should have some very nice regulators.
