    Default LX200 Power supply



    Recently received a 10" LX200 GPS from a good friend. It came with an 18 volt Sceptre AC Adaptor. The adapter is a big heavy brick and appeared to me to be high quality. I used it several times connected to a battery charger with no problems. But last night I plugged in into an AC outlet and to my other scope, which is a ETX 105. It (the adapter) started smoking and appears to be burned out. I have two questions. One, since the scope was given to me, I'm not sure if this was the original adapter from Meade. Its product number is PD1820APL6A. Input 120 VAC 60 Hz 57W Output 18VDC 2A. The LX200 and the ETX both say 12 volt adapter on the panel so is using an 18 volt adapter incorrect?? Two, I have always used internal batteries for the ETX and sometimes with the LX200. I read on another thread somewhere that this is not recommended. Any thoughts on that? Three, is it preferable to plug an adapter into my battery charger/power inverter than to an AC outlet? and my most important question is what would you recommend to replace my original adapter with? Should it be 18volts or 12?? I'm not looking to go cheap. I just want a high quality product that is unlikely to create any voltage spikes or problems with my electronics.

    The ETX supplied power supply according to the manual is only 12v so you may have damaged something using the 18v power.

    It is AN original adapter from Meade. The power supply you mention, the Sceptre PD1820APL6A, is exactly the one that came with my original Meade LX200 Classic. It is an unregulated 18V supply, which actually runs a bit higher than that, like 20V. The LX200 Classic was intended to use an 18V supply, but as far as I know the ETX was not. I don't even think the LX200 GPS was supposed to use that supply, maybe your friend also had an LX200 Classic and mixed up the power supplies?

    I don't think I damaged anything when i plugged it into the telescope. I think it started smoking as soon as i plugged it into an outlet. I smelled it but didn't react quick enough.

    That's interesting! No he didn't have a classic. But he bought this scope about 15 or so years ago when the GPS version first came out. Maybe Meade made the mix up?

    You can purchase the Meade AC power supply from most vendors if you want to use that again.

    Do not use an 18V supply for any scope but the LX200 Classic, it will harm the electronics. This is the 12V 5A power supply Meade sells for their later 12V GPS, RCX, ACF, scopes.
    I would get rid of the 18 volt Sceptre supply.
