UPS Guide Part I: What are Uninterruptible Power Supplies?

Uninterruptible power supplies, aka UPS, are devices that stores energy to provide emergency power to your electronic equipment. In other words, they act as a backup battery to protect your computer and similar devices in case of a circuit failure, outage, or similar power disruption. While the charge generally lasts just a few minutes, it gives you the ability to finish your current tasks before safely powering down. Moreover, it offers protection from internal electronic damage and unexpected losses. But how does it work?

How do Uninterruptible Power Supplies Work?

There are a few different types of uninterruptible power supplies, but the primary feature among them is called SPS, or offline/standby technology. When the power supply detects a reduction in voltage, it turns on the inverter channel to release energy from the battery pack. This ensures that the attached equipment continues to receive power, providing a great deal of safety and ease of mind.

As you can expect, uninterruptible power supplies have a wide application of uses, from the home setup to the mega server room. And, in addition to their safety features, they offer a range of benefits for a variety of situations.

UPS Guide Part II: Benefits of the Best Uninterruptible Power Supplies

We’ve had a look at the science behind uninterruptible power supplies, but the question remains– why should you invest in one for your computer workstation? Let’s have a look:

  • Safety First. The best uninterruptible power supplies feature technology like AVR and surge protection to keep your equipment (and your home) safe.
  • Protects Data. If an unexpected power outage or surge strikes your home or office, all the data on your PC could be lost– unless you’ve got a UPS waiting on standby.
  • Healthy Equipment. Electronics are not built to experience consistent power surges or an unexpected loss of power. Fortunately, you can ensure the health and lifespan of your gear with the right UPS.
  • Peace of Mind. No matter what your situation, nobody likes it when their PC or other electronics suddenly shut off. Uninterruptible power supplies are guaranteed protection against harmful circumstances, ensuring peace of mind and comfort.

In addition, there are a number of bonus perks to specific UPS models. Look for smart systems that let you monitor and protect your equipment from afar, as well as convenience options like intuitive display panels.

Still having trouble choosing the right model? Let’s take a closer look.

UPS Guide Part III: Choosing the Best Uninterruptible Power Supply for You

There are a number of things to think about when shopping for the best uninterruptible power supply. Let’s take a look at a few of the main considerations:

  • Number of outlets

  • Convenience features
  • Price

The best uninterruptible power supply is different for every situation. If you plan on protecting a server room or large home theatre, you’ll naturally need a more powerful option. That said, if it’s simply a solid gaming rig that you’re protecting, a base unit with a few outlets may do just the trick.

I have an apc smart ups , 1000 va I can’t recommend their unit as I feel it is unsafe. it may protect your computer ,but I’ve had problems with sticking relays and batteries getting so hot you have to handle them with gloves so you don’t get burned. they need to put some kind of protection on these units so the battery disconnects from the charger if a dead cell develops. I came home to a bad Sulphur smell and it was the ups .I had to remove the unit with gloves it was so hot.the battery cases were starting to melt.

Yikes! That’s not good. I’m glad to hear you’re okay.

I know that APC is almost synonymous with UPS at this point, though. Maybe one slipped through QC?

You should definitely get in touch with the company.
