Power supply for Meade ETX

Postby stormwatch » Mon Nov 27, 2006 7:56 pm


I have a power supply which I would like to use to power my Meade ETX 125 but I'm not sure if it will blow the thing up. It can be switched between 3,6,9 and 12 volts (I believe the ETX takes 12 volts). But there is a polarity switch on it and I have no idea what way to set it or if it even makes a difference. This switch has a picture on the left with negative at the top and positive at bottom, the right of the switch has the opposite (positive top, negative bottom). Which way do I set it?

Also, the current says - 500mA6VA
What the heck does that mean?
Output is direct current (DC)

Is the adapter safe to try with my scope? Any help would be fantastic thanks.

500mA6VA means it will output 6 watts - half an amp @ 12 volts.

Your scope needs 12V - current sounds a little on the thin side, but someone else can advise.
