Uninterruptible power supply is a constant voltage and constant frequency uninterruptible power supply with energy storage device and inverter as the main components. The main function is to provide uninterrupted power supply for a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS uninterruptible power supply stabilizes the mains and provides load use. At this time, the UPS power supply is equivalent to an AC mains voltage stabilizer, and also charges the internal battery; when the power supply is interrupted, the UPS will immediately provide 220V AC power to the load through inverter conversion, so that the load can maintain normal operation and protect the load. Hardware and software are not damaged.
In addition to uninterruptible
power supply, uninterruptible
power supply actually has 8
major functions, did you know?
Power Failure Protection
When the utility grid suddenly loses power, the UPS power supply system will immediately convert the DC power of the UPS battery into AC power to continue to supply power to the load, avoiding the inconvenience and loss caused by the power failure.
Voltage Stabilization
Mains voltage is easily affected by the distance and quality of transmission lines. The voltage of the user closer to the substation is higher, and the voltage of the user farther away from the substation is lower. Too high or too low voltage will affect the quality and service life of the user's equipment, and in severe cases will damage the equipment and cause heavy losses to the user. The use of UPS power supply system can provide stable voltage power supply for user equipment, ensure the normal operation of equipment, and prolong its service life.
Power-off Protection
Usually, the UPS power system will have a cutting-edge discharge design to absorb the surge, so as to avoid the impact of the surge problem on the efficiency and life of the equipment, and provide protection for the equipment.
High And Low Voltage Protection
When the mains voltage is high or low, the voltage regulator (AVR) in the UP power supply keeps the mains voltage within a usable safe range to ensure that the equipment can operate normally. When the high and low voltage exceeds the available range, the UPS power supply system will start the battery power supply to ensure the continuous operation of the equipment.
Harmonic Distortion Protection
When the power is delivered to the end of use through the transmission and distribution lines, the voltage waveform is distorted, the fundamental current changes, and harmonics are generated. Harmonics will affect the use of equipment, UPS power supply can provide stable and high-quality power supply for equipment, effectively improving the operating efficiency and life of equipment
Stable Frequency Action
The frequency is the cycle of the mains change per second, and 50Hz is 50 cycles per second. The change of rotation speed caused by the sudden change of the power consumption of the user terminal during the operation of the mains generator will make the frequency of the converted power unstable. The power converted by the UPS power supply can provide a stable frequency to ensure the normal operation of the equipment.
Instant Protection
Power supplies sometimes experience voltage surges, dips, or momentary voltage dips. Such problems can affect the accuracy of the device. In serious cases, it will damage the precision equipment and bring losses to the user. UPS systems can provide stable voltage to protect equipment.
The Effect Of Suppressing Transverse
Mode And Common Mode Noise
The transverse mode noise is generated between the live wire and the neutral wire; the common mode noise is generated between the live wire, the neutral wire and the ground wire. Invisible power problems are unavoidable, endangering instruments and equipment all the time and causing losses to users. The UPS power supply escorts the instruments and data, ensures the normal operation of the equipment and prolongs the service life of the equipment.
