As we're all dependent on technology, it's important to ensure that our electronic devices such as computers, smartphones, TVs, and others are protected from power surges, lightning strikes, and voltage drops that can cause irreparable damage. Most people use either a UPS or a surge protector, but few understand the difference between them or which to choose. In this blog post, we will compare the differences between the Uninterrupted Power Supply (UPS) and Surge Protectors to help you decide which is right for you.
What is a UPS?
A UPS, or Uninterrupted Power Supply, is a backup power source that provides temporary power to your devices during power outages or brownouts. It provides protection to devices against power surges, power bumps, sags, and even common power failures. These devices have a built-in battery that kicks in as soon as there's a power outage, allowing critical equipment to stay running without interruption until power is restored, or until a backup power source like a generator can take over.
UPSes are usually rated in VA or voltage-amperes, which is a measure of the maximum voltage and current it can supply to your devices. They tend to be bulkier, heavier, and pricier compared to surge protectors, but the added protection and peace of mind makes it worth the expense.
How does a surge protector work?
A surge protector, on the other hand, is designed to protect electronic equipment against voltage spikes caused by events such as lightning strikes, power grid fluctuations, and other electrical events. It prevents the excess voltage from reaching your connected devices, acting as a mediator between the power source and your devices. The basic function of a surge protector is to divert the excess voltage to the earth, keeping your devices from being damaged by the high voltage.
Surge protectors come in different varieties, ranging from basic to advanced models with more features. Basic models tend to have lower joule ratings and can only protect against smaller surges in voltage, while more advanced models offer more levels of protection with higher joule ratings, better surge protection capability, added features such as EMI/RFI filtering and power conditioning, and can handle larger surges during thunderstorms.
UPS vs Surge Protector: Which is right for you?
So, which one should you choose? It all depends on your needs. If you live in an area that frequently experiences power outages and needs power to stay on no matter what, a UPS is the way to go. It'll not only protect your devices from damage but also allow you to continue working during power failures.
If your area is mostly stable in terms of power outages, but you want to protect your devices from power surges and lightning strikes, a surge protector should suffice. A surge protector will protect your devices from any excess power reaching them, keeping them safe during electrical events.
It's important to note that having a UPS doesn't mean not needing a surge protector. They serve different purposes, and it's recommended to use them together to ensure maximum protection for your devices.
