Which AC adapter goes with the proper Genesis and Mega Drive?
dxm...@my-deja.com
Sega Mega Drives. Over the years, things have gotten so mixed up that
I have lost track of which AC adaptor goes with which system.
Oddly enough, I have *3* different Sega Genesis AC adaptors. All of
them are official SEGA products and say "Plug-in power supply for use
with Genesis console"
Here is what each of them say:
1) Model: 1602
(UL) Listed SA A40915
20J8 Class 2
E82323 Transformer
Input:120V 60Hz 35W
Output:9V DC 1.2A
2) Model: MK-1602
(UL) Listed SA A40915 (SA SAC A40915
20J8 Class 2 LR 60353
E82323 Transformer
Input:120V 60Hz 18W
Output:9V DC 1.2A
3) Model: MK-1602-1
(UL) Listed R 1169
13B4 Class 2
E76320 Transformer
Input:120V 60Hz 20W
Output:10V DC 1.2A
Since they all say "Genesis", I assume that I do not have the proper AC
Adaptor for the Japanese Sega Mega Drive.
Can anyone please tell me which AC adaptor goes with with Genesis? And
which one would be the ideal one to use for the Japanese Sega Mega
Drive?
Also, I have long been using a step-down converter to run my Japanese
White (light grey) Sega Saturn ver. 2.0. I just want to make sure that
I am using the right one.
It is a 220V --> 100V step down converter by "Alpha Art".
It reads:
Input: AC 200V -240V 50/60Hz
Output: AC 100V
Am I using the correct one?
Also, can I use this for my Japanese Dreamcast (when I get one)?
Any and all help would be greatly appreciated.
Thank you.

1 and 2 are for practical purposes all the same; they have the same 9V 1.2A
output (and are both1602s); they're just different revisions. The 3rd one is
odd, I've not seen one that had the 10V rating. I'm sure this is still for a
Genesis 1...I've tested a lot of these supplies and most of them actually
put out 12.5-13.5V anyway.

For certain, either of the first 2 will work on all 4 systems. The one that
would have come with a Japanese Mega Drive would have also been 9V 1.2A
output, but would have been 100V input. It might have been called a SA-160A.
When all systems had the external transformers I used to do exactly this,
run a MD on a Genesis power supply; that way I got the right voltage without
using a transformer.
These same adapters work on both versions of the SegaCD and MegaCD. The
smaller Genesis 2 and Megadrive 2 use a different adapter that puts out 10V
and .85A. It also has a different plug on the system end so you can't plug
the wrong one into the wrong thing by accident.

Assuming you're in Europe or somewhere else where your wall voltage is 220
or 240V that's correct.
If you're in the US you need one that has 120V input and 100V output; I
don't think the one you have would be working at all in that case since
you'd be running the system on effectively about 50V.

Yes. :)

Well, I received it in a package containing a Japanese model #1 Sega
Mega CD and a modded U.S. model #1 Sega Genesis.
BTW, I made a small error in its description. It's Model is "1602-1",
there is no "MK".

OK, but is there any risk of causing any amount of dameage to my
Japanese model #1 Mega Drive? Or it it perfectly safe?

Uh oh! I am in Canada, where we use the exact same electircal current
you guys do.
What does this mean for my using that converter, then?

Well, this one is 200V - 240V, isn't that more than enough? Is that a
potentially bad thing that it is som much more? Please excuse my
ignorance. I know practically nothing about electricity about
electricity.

Well, I have been using it all this time, and, to my knowledge, I
haven't encountered any noticeable problems so far. But I do not want
to take any chances with my precious Japanese Sega systems.

Does this change since I am in North America?
Thanks for all your help Raymond!

input, not 120V. Since it has the same 'main' model number, 1602, I'm sure
Sega considers it equivalent.

It's fine. It gives the correct output, in fact better for the US since it's
meant to be plugged into 120V instead of 100V.

Who knows? It's not correct that's for sure. Normally a transformer just
steps down the voltage proportionally. If that's the case, this one is
intended to take 240V down to 120V, a 50% ratio. So, if you plug it into
120V it probably outputs only 60V. I'm surprised your Saturn will even run
on that.

That's not how it works. The input needs to match what your wall outlet puts
out (i.e. 120V if Canada is like the US as you said above).

Well, low-voltage may not really hurt, but I'm surprised it's working at
all.

Yes, you need a different transformer for it and for your Saturn.
You want a 120V input 100V output one. If that's not available where you are
you can order one from The Electronic Connection, 1-800-345-0101. I think
the price was around $40-50 US.
Don't plug the Genesis power supplies into the above, even when using them
on the MD, just plug them into the wall.

A little extra info. Checking, I too have one of these 1602-1 supplies with
the 10V output. Mine must have come with a SegaCD2. I measured its output
compared to the regular 9V 1602; I got about 13V out of the "9V" version,
and about 13.6V out of the 1601-2.
Maybe somewhere along the line they decided the CD2 needed a bit more
voltage? Who knows?
