A 4:1 transformer comes to mind.
It would have to a basic analog wire wound transformer though, not an electronic "DC converter". From: AF <af-boun...@af.afmug.com> On Behalf Of Gino A. Villarini Sent: Monday, December 05, 2022 11:05 AM To: AnimalFarm Microwave Users Group <af@af.afmug.com> Subject: [AFMUG] Voltage Attenuator? Picking your brains this morning! I need to monitor a 48V battery bank in order to activate some actions on a Control by Web X420 device. The x420 only takes up to 12v in the analog input, how can I linearly attenuate de 40-50V range in to a 12v range to make this work? <https://aeronetpr.com/> Gino Villarini Founder / President @GVillarini 787.273.4143 | <https://www.inc.com/profile/aeronet> <https://www.facebook.com/aeronetpr> <https://www.instagram.com/aeronetpr/> <https://www.linkedin.com/company/aeronet-broadband-corp> <https://twitter.com/aeronetpr> <https://www.youtube.com/user/AeroNetPR> <https://wa.me/17872734144> Metro Office Park #18 Suite 304 Guaynabo, PR 00968 <https://homefi.pr/>
