Making Uninterruptible Power Supplies

I have been buying APC uninterruptible power supplies for over 15 years now and they always work great. One of the biggest reasons I buy APC is their dynamite tech support. They really go out their way to help you if you have any questions or problems. The Power-Saving Back-UPS Pro 1500 which I have two of are second to none. This unit is worth it's weight in gold. It is very powerful and compact.

I needed a LARGE Uninterruptible Power Source for an industrial grade Flat Bed Printer. It needed to be single phase 208V, 3,000VA output capacity. This unit by APC weighs in at 105 pounds so it's no light weight! Unpackaged and set up in a matter on minutes as the factory default settings is adequate for the intended use. The machine can be configured for use in a data rack where you can set it to for a controlled shutdown of servers and after power is restored a controlled restart, selecting 3 different power zones to restart in sequence to get your network back up and running without any user input needed. It is about the size on a large desktop computer and comes with Data Rack mounting hardware or can be used with included floor stabilizing feet.

one of the best power supplies purchased to date!

BEWARE The kit does not come with power supplies.

I purchased this about 2 weeks ago as a replacement for my uninterruptible power supply on my computer equipment. Less than a week ago we had another power failure that lasted about 3 hours. The EcoFlow River 2 Pro performed better than I had hoped. It transferred power seamlessly and none of my equipment even sensed it had happened. The app made it easy to manage my power usage to insure that the most critical electronics remained available.

I did not start out to want an uninterruptible power supply, but only a very capable surge protector. Once I read about the benefits of an uninterruptible power supply I was convinced I had to have one for my equipment. Initially this unit was on back order and I was sure getting one would be taking a very long time. Thankfully the day came when B&H gave me the email saying my Cyberpower EC850LCD was on it's way. I've had it protecting my computer, Time Machine and external hard drive. So far just this week the unit gave me the time to shut down safely after a short electrical blackout. I know this was a wise purchase and I am grateful to B&H for their commitment to honor my order.

I use it to provide conditioned power (uninterruptible as well) to my computer and all peripherals. The automatic voltage regulation is as, if not more important to sensitive electronics. Under voltage and over voltage can do bad things to electronics and it is not as apparent as a power outage, spikes, or brownouts. I have another of the same on my TV, cable modem, DVD player as well. You hook it up, it works, you do nothing (except change the battery every couple of years). I have a Mac and their software doesn't run on a Mac. But it is no big deal as you really don't need it.

The APC Smart-UPS series stands out as a robust and reliable choice for uninterruptible power supply (UPS) needs, catering to both small office environments and larger enterprise setups. Renowned for its durability and performance, the Smart-UPS has earned a solid reputation among IT professionals and businesses. One of the standout features of the APC Smart-UPS is its exceptional reliability. It’s designed to offer consistent power protection with advanced battery management, ensuring your equipment stays operational during power outages or fluctuations. The UPS units provide seamless power transfer and clean, reliable output, which is crucial for sensitive electronics.

It's a power supply which supplies power. Who'd have thunk it?

Not much to elaborate on here. The power supply does what it is supposed to do. That is, it supplies power. A haiku: This power supply works Supplies electricity To my pocket cam
