  • What three components power the UPS system receives

    What three components power the UPS system receives

    At its core, every UPS contains three main components: a battery (or bank of batteries), a rectifier that converts AC wall power to DC for charging those batteries, and an inverter that converts stored DC power back to AC when your equipment needs it. A UPS (uninterruptible power supply) is a device that sits between your equipment and the wall outlet, providing backup battery power when electricity fails and cleaning up the power your equipment receives the rest of the time. The inverter then converts DC power back into AC to keep your systems working during a power source disturbance. Charger: Often separate in large UPS systems, it charges the battery. Output Distribution Module In process industries, the rectifier is a crucial component within a UPS (Uninterrupted Power Supply) system.
