Dave Smith Posted March 10, 2011 Share Posted March 10, 2011 I and many others use one of the Maplin power supplies. Mine is the 10A version so there is plenty of power available for the mount and dew heaters.Dave Link to comment Share on other sites More sharing options...
G2EWS Posted March 10, 2011 Share Posted March 10, 2011 Hi Paul,Lots of power supplies out there and as Dave suggests Maplin is a good source. Or you might have a spare supply hanging around?Important thing is to make sure the polarity is correct. If you have a power socket check what the centre and outer polarity is, then make sure the supply is the same way round. Sorry if I am teaching you to suck eggs but you don't want to blow your kit up!RegardsChris Link to comment Share on other sites More sharing options...

RascalUK Posted March 10, 2011 Share Posted March 10, 2011 Hiya Andy does that supply from eBay plug straight in to your SW mount or did you need another lead? Link to comment Share on other sites More sharing options...
G2EWS Posted March 10, 2011 Share Posted March 10, 2011 Hi Rascal,Looks like the supply plugs straight in. As mentioned above, just check that the polarity is the correct way around.I would normally be very wary of buying an item such as this off eBay. Whilst is mentions approvals, you need to be confident that this company is a legitimate one and not someone operating from overseas or from their back garden whom disappear when your house burns down. I would also check out the approvals to make sure they are relevant.I obviously cannot vouch for or otherwise, but if a member on here - Andy - has one then it can only be a good thing. All I suggest is you be aware before buying. I have seen many products not up to standard causing all sorts of problems!Best regardsChrisps I hope I have not worried you unduly, but I am very cautious about these things. Particularly so as I am an electronics engineer. Link to comment Share on other sites More sharing options...
Andyfx Posted March 10, 2011 Share Posted March 10, 2011 Hi guys.Yes the power supply does plug straight into my Skywatcher Alt Az mount, the jack is of the correct size and polarity. The only downer is that the lead with plug attached is short, however this is easily extended in a safe manner for outdoor usage and it beats paying out for 8 batteries at a time!
