When it comes to protecting your valuable electronics from power surges and spikes, a surge protector is an essential tool in your arsenal. But have you ever wondered what that blue light on your surge protector means? Is it just a fancy LED indicator or does it serve a more significant purpose? In this article, we’ll delve into the world of surge protectors and explore the significance of the blue light that often accompanies them.
What is a Surge Protector?
Before we dive into the meaning of the blue light, let’s take a step back and understand what a surge protector is and how it works. A surge protector, also known as a surge suppressor or surge diverter, is a device designed to protect electronic equipment from voltage spikes, surges, and other forms of electrical interference. These devices are typically plugged into a wall outlet and then have multiple outlets to connect your electronics, such as computers, televisions, and gaming consoles.
Surge protectors work by absorbing or diverting electrical surges, thereby preventing them from reaching your connected devices. This is achieved through the use of specialized components such as metal oxide varistors (MOVs), thermally protected metal oxide varistors (TPMOVs), and surge-rated TVS diodes. These components are designed to detect and respond to voltage surges, clamping or diverting the excess energy away from your devices.
