2 out of 3 ain't bad. bp <part15sbs{at}gmail{dot}com> On 7/11/2019 5:16 PM, Sterling Jacobson wrote: They are also hella expensive, lol   From: AF <af-boun...@af.afmug.com> On Behalf Of Bill Prince Sent: Thursday, July 11, 2019 6:05 PM To: af@af.afmug.com Subject: Re: [AFMUG] Still need help 50v DC regulator 6-10A   These units from Phoenix Contact will do 5-7 amps, and can be wired in parallel to increase output. They're also DIN rail. https://www.phoenixcontact.com/online/portal/us/?uri=pxc-oc-itemdetail:pid=2905008&library=usen&pcck=P-22-05-01&tab=2&selectedCategory=ALL   bp <part15sbs{at}gmail{dot}com>   On 7/11/2019 3:50 PM, Sterling Jacobson wrote: Ok, so instead of a 48v battery string, use a 24v battery string and connect up two 24v to 10A supplies on it and then connect the load/output side in series for 48v?       From: AF <af-boun...@af.afmug.com> On Behalf Of Ken Hohhof Sent: Thursday, July 11, 2019 4:08 PM To: 'AnimalFarm Microwave Users Group' <af@af.afmug.com> Subject: Re: [AFMUG] Still need help 50v DC regulator 6-10A   I’d use a Mean Well RSD-300C-48, but it’s not DIN rail mount and won’t meet your 10A requirement.   One thought is that most isolated output DC-DC converters can have their output put in series, you could put two 24V 10A supplies in series.   From: AF <af-boun...@af.afmug.com> On Behalf Of Jesse DuPont Sent: Thursday, July 11, 2019 4:26 PM To: AnimalFarm Microwave Users Group <af@af.afmug.com>; Sterling Jacobson <sterl...@avative.net> Subject: Re: [AFMUG] Still need help 50v DC regulator 6-10A   How about this one? It's only 5A, though, could run a pair of them and split the load. https://www.trcelectronics.com/View/Mean-Well/DDR-240C-48.shtml On 7/11/2019 2:59 PM, Sterling Jacobson wrote: Sorry to beat a dead horse, but I’m still stuck on this mini-pop DC plant thing.   Is there a DIN mountable voltage regulator that will allow me to feed load from 48v battery string without going over 50v at 6-10A?   I’m still trying to power a couple of MetroLinq 2.5 antennas at the site, but people tell me they explode if given more than say 52v.   Which means my float battery system will kill the radios if it goes into recharge mode at 54v?   Or am I overthinking things?   Looks like to solve this I would need something like Mean Well $100 SD-350B-48 between the battery array and the load to assure it sticks around 50v.   Is that my only solution here?
