 | | A/C Adapter for RCX 1.0
|
|
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 (...) (20 years ago, 30-Mar-04, to lugnet.robotics, lugnet.robotics.rcx, FTX)

(...) 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... (...) Trains still continue to use 9V AC adapters, so buying one (...) (20 years ago, 30-Mar-04, to lugnet.robotics.rcx, FTX)

(...) 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 (...) (20 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)

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 (...) (20 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)

(...) Does it have a switch, or does it just magically figure out what voltage to supply? (...) I have no idea. You'd really need to ask someone who understands the guts of the RCX. I also have no idea why TLC would use strictly AC adapters when the (...) (20 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)

(...) The RCX has a bridge rectifier inside, that converts the AC to DC. It also has a voltage regulator that allows it to take a fairly large input voltage range. You can safely power it with a DC supply, however I wouldn't recommend leaving it on (...) (20 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)

(...) When a fellow MichLUGer brought up the question of hooking up an external power supply to a 2.0 RCX, a lot of these interesting little facts popped up. From the way it sounded, the RCX has a maximum amperage draw, and each side of the bridge (...) (20 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)

The 1.0 RCX with AC adaptor jack takes 9-12 volts. I have been running one on a 12 volt adaptor for ages, and no damage. I think the RCX also includes some protective circuitry, so you shouldn't have any trouble, especially with an adaptor LEGO sent (...) (20 years ago, 22-Apr-04, to lugnet.robotics)
