Power supply for EAF

Post by cbutterworth » Mon Jan 13, 2020 5:38 am

The Zwo EAF works great with my WO Zenithstar 103. It was easy to install and setup.

My only problem is the power supply.

I use a 12v AGM battery and the voltage fluctuates somewhat (as these type of batteries do). However, I cannot find details in any of the Zwo information on the voltage tolerances of the EAF.

From other Zwo users, I have gleaned that using a battery is fine and that a voltage of between 11.5vdc and 15vdc is fine. Other users report that 12vdc should be provided via a regulated supply.

Should I use the battery, I can equip it with a 1 or 2 amp fuse, but am still a little worried. Seems to me that a well designed product would have taken into account the various power sources used by astronomers.

Any ideas?

Thanks,
Charlie

Does anyone have an answer to my straightforward question?

Given that this is the official Zwo support forum, I’d have expected a response by now.

If this forum is an indication of the quality of Zwo support, then maybe I’ll return my Zwo EAF and buy a Pegasus Cube.

Sorry for the late response.
We recommend 12V power supply for EAF. The tolerance is 10-16V.
