The function and function of UPS uninterruptible power supply

Ups Power Supply Introduction UPS is the abbreviation of the English name of Uninterruptible Power System. It is accompanied by the birth of computer and is one of the commonly used peripheral devices of computers. In fact, the UPS is a constant voltage and constant uninterruptible power supply that contains an energy storage device and is mainly composed of an inverter. In the early days of its development, UPS was only considered a backup power source. Later, due to voltage surges such as voltage surges, voltage spikes, voltage transients, voltage drops, continuous overvoltages, undervoltages, and even voltage interruptions, the electronic systems of computers and other devices were disturbed, resulting in damage to sensitive components and loss of information. The serious consequences of disk programs being washed away, causing huge economic losses. Therefore, UPS has received increasing attention and has gradually developed into a power protection system with functions of voltage regulation, frequency stabilization, filtering, anti-electromagnetic and radio frequency interference, and voltage surge prevention.
A wide variety of UPS power supplies are currently available on the market, with output power ranging from 500VA to 3000kVA. When there is a mains supply to the UPS, the UPS supplies power to the computer after regulating the mains (220VÂ±5%). At this time, the UPS is an AC mains voltage regulator, and it also charges the internal battery. Due to the difference in UPS design, the range of UPS adaptation is also different. The change of UPS output voltage within Â±10-15% is generally a normal computer use voltage. When the utility power is abnormal or interrupted, the UPS immediately converts the power of the battery in the machine to the computer system through inverter conversion to maintain the normal operation of the computer system and protect the software and hardware of the computer from loss.
