[AFMUG] Tower UPS's (again)
We've been using the APC SmartUPS 750XL as a Tower UPS for several years. Put 2-8 100+AH AGM Batteries on them, and they've been rock solid for us. I can think of only a handful of failures in the dozens deployed over the last several years. I used to source them off ebay for $50-$70 each, but they're becoming more and more scarce. Anybody have a recommendation for a simple UPS that will do all the monitoring that the APC does and accept big batteries? We're a Metro-Rural Area, our power outages are usually measured in Hours, not days. So I'm not as concerned with the inefficiency of doing the DC/AC/DC Conversion for Runtime, just power stability during outages/fluctuations.I like the ease of connecting the external batteries to the APC, since the XL line has an Anderson plug on the back for them, and has a larger charger than the normal UPS, so recharge times are very quick. When the boss goes to the WISPA Shows, his head is filled with all kids of ideas, so he want's me to investigate doing everything as a DC Plant, When I price that out, with chargers, voltage converters (24/48), inverters, fuse protection, LVD, Monitoring, etc, it always seems like the price is a couple hundred dollars of parts and it would be cobbled together. Am I missing something with doing a DC Plant? I see the telco's at the sites using a rackmount rectifier with power supply modules, but those are a several hundred by themselves, and they are only 48V, they don't have to worry about 24v radios. When I build a site now, I drop in 2 batteries, and the APC, and the site is up and running in a couple minutes. A DIN rail with a couple power supplies and the box is done, and has fully monitored power, and I can plug in whatever I want without any equipment modifications. -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
Re: [AFMUG] Tower UPS's (again)
I don't trust UPSs for critical backup. I don't trust normal gel cells. On the cheap, solar charge controllers make great rectifiers. They treat the batts well and maximize your charge after a power outage. They are not as costly as a carrier grade rectifier. You can literally power them off of a cheap battery charger. I am of the camp that you don't need LVDs. You want to keep the system running until it just quits due to low voltage. The LVD crowd says you have to save the battery. Well you really should have a back up generator if the power is so erratic that a LVD might be called into action more than once a year. And if it is that seldom, let it run down. A few deep discharges is not going to kill the batt and you may just stay online long enough for the power to come back on. If you do want to use carrier grade rectifiers, I would go with eltek/valere They are modular and can be found on Ebay for reasonable amounts of money. If you do a rack with a BC-2000 you can even do battery discharge tests remotely to check for bad cells etc.And you can have redundancy in the charging. Right now on Ebay, there is a whole shelf for $400 That is a killer deal. 3 rectifier modules. -Original Message- From: Nate Burke Sent: Monday, June 28, 2021 10:57 AM To: Animal Farm Subject: [AFMUG] Tower UPS's (again) We've been using the APC SmartUPS 750XL as a Tower UPS for several years.

Re: [AFMUG] Tower UPS's (again)
You already pointed out the major plus to A/C power: It's simple. Any joker can come along and plug something in. Almost every device has a 110VAC option. UPS's are looking cheaper because you're getting used/refurb. You'll come out more comparable with a new DC system compared to a new UPS with similar runtime and capacity. I've never had a UPS as reliable as a rectifier. A handful of failures out of dozens over several years does not actually sound reliable at all. It's obviously tolerable to you in your scenario, but it's not telecom reliability. Scale that up to 100's of deployments and you'll be chasing dead UPS's more often than you'll want to. The good rectifier systems will be -48v because that's the standard for telecom power. If you're in Ubiquiti/Mikrotik land you'll have to use converters to +24V. If you're in Cisco/Juniper/Arista land then it can all be -48v and then you don't need the converters. I absolutely have been where you are now. If you're on a budget where what you can afford is the used APC XL then maybe you just stick with that. DC plant is better, but you will pay more for it and you'll pay more for the routers and switches designed for it. These are all statements of opinion, but it's opinion informed by 22 years of playing this game. -Adam -Original Message- From: AF On Behalf Of Nate Burke Sent: Monday, June 28, 2021 12:58 PM To: Animal Farm Subject: [AFMUG] Tower UPS's (again) We've been using the APC SmartUPS 750XL as a Tower UPS for several years.

Re: [AFMUG] Tower UPS's (again)
How do you distribute the 48/24v power? A row of fused links? circuit breakers? That's always been the part that looks cobbled together. I see Windstream rectifier racks with wire nuts, and wire just hanging out in the open, and an autozone inverter sitting on a shelf, so apparently even the Telco's don't always have good solutions.

If you’re looking for DC gear for the tower, I have a bunch of sentinel ups shelves with rectifiers we’re going to offload from an acquisition.

Their Modular system is a couple thousand USD ..depending what modules you get. IDK what the setup from the PDF costs, but it looks pretty clean. If you can afford a setup like that you won't regret having it.
