An uninterruptible power supply (also called UPS) is a very complex unit that is used for protecting certain devices from power spikes, power outages, while also offering backup capabilities, a backup battery in our case. The backup battery can keep supplying any device connected to the UPS with constant 220V for about 15 \u2013 20 minutes, depending on the battery amper capacity or UPS power. You can think of UPS as being the \u201cguardian angel\u201d of the electrical devices.<\/p>\n\n\n\n
Line-interactive UPS have an AVR function that helps regulates electricity, bringing it to a constant voltage that the electrical devices require. I will talk more about that further in the article.<\/p>\n\n\n\n
Do you want to know more about why it\u2019s critical to have every electronic device connected to an uninterruptible power supply? Read on.<\/p>\n\n\n\n
As a security system installer, I learned that it\u2019s critical to install uninterruptible power supply unit for every surveillance system or alarm system. Most security systems internal circuits work with small currents such as 12V or 24V. Because the systems themselves use 220V input to power up, if the current isn\u2019t regulated properly, a small spike could eventually burn the internal circuits from all the electrical power excess. HDD\u2019s are also incredibly sensible! Why do you think PC\u2019s have always been so sensitive to power spikes\/outages?<\/p>\n\n\n\n
My boss doesn\u2019t even give a warranty for any part of a security system the client might buy. Because he knows that, in the case of a malfunction, the main reason would be improperly usage of the devices.<\/p>\n\n\n\n
Most uninterruptible power supplies are not recommended for weld equipment or air conditioners unless you are using over 2 \u2013 3 kVA dynamic UPS units. I literally saw one UPS burn in front of my eyes because of this.<\/p>\n\n\n\n
