Uninterruptible Power Supply Functions and Applications

An uninterruptible power supply, or UPS for short, ensures that computer systems continue to operate for a period of time after a power outage so that users can save information urgently. Users will not lose work or lose data due to power outages. UPS can provide a timely power supply, of course, there are other functions. ATO.com will introduce the functions and applications of UPS.

Functions

• Emergency use: UPS prevents accidental power failure and affects normal work.
• Daily use: Eliminate power supply pollution such as surges on the mains, instantaneous high/low voltage, wire noise and frequency offset, improve power quality, and provide high-quality power.

For these two functions, the following UPS experience is for your reference:

• The too-light load may cause deep discharge of the battery and reduce the service life of the battery.
• Proper discharge helps to activate the battery. If the mains power is not interrupted for a long time, the mains power should be cut off every three months, and the UPS should be used to discharge the load once, which can prolong the service life of the battery.
• Most small UPS should be turned on after work, and avoid starting with the load when starting up. The UPS should be turned off after getting off work. For the UPS in the network room, it can run all day.
• Do not bring inductive loads to avoid damage, such as money counters, fluorescent lamps, air conditioners, etc. It is better to control the output load at about 60%, and the reliability is higher at this time.

Applications

The reason why the UPS can continue to supply power to computers and other equipment after a power failure is because there is a device that stores electrical energy in it, which is the UPS battery.

Nowadays, ATO 300W-8000W uninterruptible power supplies are widely used in mining, aerospace, industry, communications, national defense, hospitals, computer business terminals, network servers, network equipment, data storage equipment, emergency lighting systems, railways, shipping, transportation, power plants, substations, nuclear power plants, fire safety alarm system, wireless communication system, program-controlled switchboard, mobile communication, solar energy storage energy conversion equipment, control equipment and it's emergency protection system, personal computer, etc.

Advantages

Its main advantage is its uninterrupted power supply capability. When the AC input of the commercial power is normal, the UPS rectifies the AC power into DC power and then inverts the DC power into a stable and impurity-free AC power for the subsequent load. Once the AC input of the mains is abnormal, such as under voltage, power failure or abnormal frequency, the UPS will enable the backup energy, and the rectifier circuit of the UPS will be turned off.
