(We’re going to focus on two classes of UPS systems in this review. If no load is specified, you should probably avoid that product. A UPS with a runtime of 10 minutes at 50% load is basically the same as a UPS that runs 5 minutes at a 90% load. Look for a load number attached to runtime calculations. This is a number you should pay close attention to, as manufacturers can be sneaky here. Runtime – Runtime is the length of time you can expect a given UPS to operate on battery power.Backup only style UPS systems must switch to battery power under all of these conditions.
This is a much cleaner way of handling these types of problems, helps preserve battery life, and is quieter in operation. Line interactive is a technology that allows the UPS to correct many spikes, under-voltage, and over-voltage situations without switching to battery power. Line Interactive Conditioning – Some UPS systems are line interactive, while others are backup power only.There are several ratings and categories that UPS systems fall into, and many ways that manufacturers manipulate those numbers to make them look better on paper. It’s important to choose wisely when considering products in this category. So let’s talk about what makes a quality UPS for home users. It is very common for the batteries to fail, the components to just stop working when you need them most, and to be unable to get warranty replacement from the hardware vendor due to all kinds of disclaimers and limitations in their standard warranty. Unfortunately, selecting a quality UPS for home use is a difficult process because there are just so many terrible products in the UPS marketplace these days. By selecting the best UPS for home use, you’ll be able to safely power and protect many of your home electronics when the power grid is not behaving. They can even be used to charge your cell phone, tablet, or laptop in the same event. They provide power to your computer, television, or other devices when the power is out.
The UPS or Uninterruptible Power Supply is a fantastic appliance to add to your home.
