What power setup

[TomBoChaz]

Hi

I have a celestron cpc gps 800 and I have recently put it into a personal obs that I have built.

I would like to get a dew heater tape for the corrector and associated controller and I would also like to change from using a rechargeable powertank to something more permanent.

I have electricity to the obs and would like them all to be powered from the mains.

Have you any advice on what the bit(s) in the middle need to be?

Regards

Doing it properly and safely, a bench power supply would be the way to go, something like this Maplin type, has all the protection features you will need built in....

Thanks Tinker1947, do you know if I would need anything else to make the connections, ie, cables, or would that be able to do dew tapes and connect to my telescope?

You really should be looking at a "regulated" power supply for the scope etc http://www.maplin.co.uk/13.8v-regulated-mains-power-units-231 This provides exactly 13.8v (the same as a fully charged "12v" battery!). You would be best getting the largest size 7A as even this is only rated at 5A for continuous use. The dew heaters will run from an unregulated supply if you wish as they are less critical over their supply.

Thanks Bizibilder. Do you know if I can connect scope and dew heaters to it?

I've just replaced my Maplin 5A regulated supply with a Fusion 15A model

Had to make one small modification, the fan tends to seem quite loud at 2am ! - a small 10K pot sorted that out

I've got the Maplin regulated 7A one - works fine Running mount, dew heaters and camera cooling off it.
