Uninterruptible Power Supply: What It Is and How It Works
What Are Main Types of Uninterruptible Power Supply? Typically, according to different working principles, UPS power supply covers standby (offline) UPS, line-interactive
An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
Uninterrupted power supply batteries are an essential part of a UPS system. They are the stopgap measure designed to briefly supplement power when the main power source fails. UPS batteries are a key feature in the instantaneous response to power outages and are critical to the protection of sensitive electronics and devices.
Typically, according to different working principles, UPS power supply covers standby (offline) UPS, line-interactive UPS, online (double-conversion) UPS. The standby UPS system offers only the most basic features, providing surge protection and battery backup. Thus, its power supply quality is not good enough and the cost is much lower.
Uninterruptible power supply systems are important tools that guarantee reliability and the protection of essential electronics. The ultimate goal of UPSs is the protection of all forms of electrical devices against any form of power supply anomalies.
