I bought an RCX with an AC adapter jack and an AC adapter from Pitsco. They
arrived today. But when I opened the adapter I saw that it outputs 12V, not
9V. It’s an old Dacta AC adapter from 1996 (copyright date on packaging). I
already tried using it with my RCX and measured the motor outputs, and I got
about 9.5V for all of them. Do you think this adapter could cause damage
over time? I want to know if I should send it back and use my 9V train AC
adapter instead.

The LEGO adapters output AC voltage, but most retail adapters output DC,
which will burn out your RCX. I’ve heard that you can find AC-output
adapters at Radio Shack, but...

Can I get a 9V adapter from LEGO? I also have one lying around someplace
that lets me choose the output voltage . . . I could use that, too, but I’m
a LEGO purist. Heh.

Trains still continue to use 9V AC adapters, so buying one isn’t a big deal.
You can find them listed separately on
Bricklink, but if you buy
them from S@H you have to buy the whole
Train regulator.

Wait, are you saying the RCX runs on AC power?
You are right that the 12V adapter I got puts out AC. I didn’t notice that
before -- I thought it was an AC to DC converter. Then I checked my train
adapter, and it’s identical to the one I just bought. How about that!
Now I’m confused. Is the RCX AC or DC when it’s plugged in? What about when it’s
using batteries?

| I must also be blind. In tiny raised print just above the port on the RCX, it says "9-12V~". Had I seen that I would never have asked my original question in the first place. But I'm still curious about whether the RCX runs on AC or DC power. Does (...) (21 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)
