¿ªÔÆÌåÓýYes ¨C what he said ;) ? Don¡¯t worry about amps, just make sure whatever you are using for up-converting the voltage can handle at least 5 amps ? Thanks ? Brian ? ? Brian Valente Brianvalentephotography.com ? From: Losmandy_users@... [mailto:Losmandy_users@...]

I now use it at 17V adjusted.? The system consumes the amps it needs to function.?? ? How many amps?.... ? I measured the amps my CG11 / Gemini1 and GM8/Gemini1 takes... under 0.5 amp sidereal tracking... and just under 1 amp fast slewing.? On the CG11, I've got a very heavy Meade LX200R 12 inch and its counterweights mounted.? So outputting even 2 amps will be sufficient ...if the supply can keep it reasonably level.?? ? The key word "level" meaning free from a lot of ripple in voltage (the modern AC/DC supplies use small buck-boost high frequency like 400 kHz to do that...not big AC 60 cycle transformers any more).? So people prefer larger amp rated supplies like 4 amp to 5 amp.? But I still get good results from even 2 amp DC output rated supplies, like the 12V ones used on external hard drives.? ? ? Hard also to know how the China made supplies are really "rated" since cheating on specs gets you more profit.? So I'd sguest you use a 3 amp to 5 amp rated AC/DC supply.?? ? ( Now that they are field tested, I'm going to make up some more of my own booster boxes with the volts and amps display.? These are really nice and compact...the DC plug goes in and it will have either Gemini1 4 pin Power cord or Gemini2 power cord out.? Let me know privately if interested....I'll send some pictures ...) ? Have fun, Michael? ? ? On Jan 4, 2018 2:35 PM, "taylorwab@... [Losmandy_users]" <Losmandy_users@...> wrote:
