24 Volt DC UPS System
24 Volt DC UPS System
(OP)
Hi All, We have a number of data loggers deployed in the field recording data from various sensors. They all require 24 Volt DC power supplies and each draws about 950mA. To ensure that they keep running during interruptions to the mains I would like to connect them to a UPS.
I have found a couple of suitable devices manufactured by MEANWELL. Anybody have experience with this device from MEANWELL https://www.digikey.ca/en/products/detail/mean-wel.... Will it do the job? Any suggestions for other devices?
Thanks

Caveats:
1) Their noise or ripple ratings are usually lousy. Check that what it delivers won't mess with your data loggers.
2) Some of their measurements tend to be done in some way that hammers their output noise but that you might not be adding to your setup, making the noise much worse.
3) ALL their supplies of any kind have jaw dropping inrush currents. Make sure this won't cause your line supply to choke or the blinks that they always cause don't create problems for you.
If you can see your way thru these things then they're a great bargain.
Let us know how it works out.

You want something like a Phoenix Quint4 setup. A complete system is three parts - 24VDC power supply, UPS module and battery.

RE: 24 Volt DC UPS System
itsmoked, that info is useful. The main thing that attracted me to the MEANWELL was the reasonable cost. LionelHutz I'm pretty sure the MEANWELL DRC-40B (described in the link) can be set up to provide a DC UPS system by adding a battery. It's clearly described in the datasheet. However, that is kind of what i was looking for feedback on as I wasn't sure how well it performs when used as a UPS. ThE Phoenix Quint4 might be a better system but also appears more costly. MEANWELL also make the DR-UPS40 which is setup in a similar way to the Phoenix system (i.e. 24VDC power supply, UPS module and battery).It also has a much higher rated current (40 Amps) which is higher than the DRC-40B (0.95A). Our loggers only draw about 0.95A.
Im not sure which would be the best setup to go with which is what I was hoping to get some feedback on.

I'd give the 40B a shot at that price. Get one and mess with it.
