About this product

Model:  lynxastro_12v5a_ln_psu_uk

Our BEST 12v / 5A Mains Power Supply! 

A medical grade PSU that delivers smooth, dependable, low noise power. Even at sub-zero temperatures. 

Regular power supplies with 12V nominal voltage are designed for indoor use, when used outside in the cold their voltage drops (at -10°C the voltage output may reduce to only 10.5 V). This reduction in voltage can cause a mount’s motors to behave erratically. Indeed most apparent faults with modern mounts can be traced to an inadequate power supply. 

Suitable for use with most modern computerised GOTO mounts with power requirements up to 5 Amps, including the Skywatcher AZ-GOTO, AZ-GTi, HEQ5, NEQ6, and EQ8 (with optional adapter) and Celestron SLT, SE, Evolution, CGEM, CGEM DX, CGE Pro, CPC, CPC Deluxe, CGEM II, CGX and Advanced VX mounts. 

Note this power supply has a fully enclosed plastic casing but should not be used in wet conditions. 

Supplied with a 2m, 3-pin UK-type C13 plug. 

Total cable length 2.9m.

It does the job

A relatively small, but so so useful addition to the growing collection of accessories ... and it does exactly what it's supposed to do.

It works, but
Tuesday, 12 October 2021  | 

The power supply works fine, in that it supplies adequate power to my new Celestron VX mount. However, the connection to the socket on the mount is not really up to the job. The slightest movement of the plug and the connection is lost, which means having to go through the setup and alignment routine again. The problem seems to be that the plug, although it clicks on insertion, does not go in far enough and remains very wobbly; there is no ring on the plug, unlike the car battery connector cable supplied with the mount, which enables you to screw the plug on to the socket. If you accidentally brush against it you lose your power. So, if you want a mains power supply for your VX mount, make sure you get one with a screw locking ring on the plug to hold it in place

Good Quality Supply

I bought this supply to replace an old one that was causing interference problems with my Lynx Astro EQDIR cable and AZ-GTi mount. I'm glad to say it has done the job, good quality supply and the mains cable is reasonably long making it easier to use with a mount than some cheap brands that have very short cables.

FLO advised us to buy this to power the ASIair Pro and so far it works well. The ASIair pro does get a little hotter with this supply than another that we use with a different telescope but we are sure this will be a better supply when we add other peripheries such as dew heaters etc
