What is the use of uninterruptible power supply reddit? UPS, which means "uninterruptible power supply reddit" in Chinese, is the abbreviation of "uninterruptible power supply" in English. It can protect the computer system to continue to work after a power failure for a period of time, enabling users to emergency inventory, so that you do not affect the work or data loss due to power failure. It in the computer system and network applications, there are two major roles: one is emergency use, prevent the sudden power failure and affect the normal work, damage to the computer; It is to eliminate the surge, the instantaneous high voltage, instantaneous low voltage, electrical, noise and frequency offset and other "power pollution", improve the quality of power, to provide high quality power for the computer system.
Line while the power UPS keeps the computer working? Yes, because when the UPS is powered on, it will start immediately (generally no more than 10ms), and its battery power inverter will convert alternating current to the load and power supply, so that the computer can work and prevent some important information from being lost.
What is overload protection? Answer: Under the inverter's working condition, when overloaded, the output voltage is relatively low, the load back to the rated power, the output voltage back to the specified value, to avoid the computer operation due to open the surge current of other equipment instantaneous overload and shut it down. Automatic in case of severe overload power off.
What is short circuit protection? A: It means that some devices can monitor the abnormality of the working circuit (such as short circuit). When the abnormality occurs, the alarm will sound and cut off the circuit to prevent further damage. Typical short circuit protection is the fuse, short circuit, the current is very large, fuse blown, short circuit power supply.
