Huawei UPS power supply is a kind of constant voltage and frequency uninterrupted power supply with energy storage device and inverter as the main component. Its main function is to provide uninterrupted power supply for a single computer, computer network system or other power electronic equipment. When the city power input is normal, the UPS uninterruptible power supply stabilizes the city power and provides load use, at this time the UPS power supply is equivalent to an AC city power regulator, and at the same time it charges the battery in the machine; when the city power is interrupted, UPS will immediately put the power of the battery in the machine and continue to supply 220V AC power to the load through the inverter conversion method, so that the load can maintain normal operation and protect the load software and hardware from damage.

Huawei UPS power supply in addition to uninterrupted power supply, in fact, there are 8 major functions, do you know?

1. Power outage protection

In the event of an instantaneous power outage in the municipal power grid, the UPS power system immediately converts the UPS battery DC power into AC power to continue to power the load to avoid the inconvenience and loss caused by the power outage.

2. Voltage stabilizing effect

The municipal power voltage is easily affected by the distance and quality of the power transmission line. The user voltage close to the substation is higher, while the user voltage far away from the substation will be lower and lower. Too high or too low voltage will affect the service quality and service life of the user's instruments and equipment, and when it is more serious, it will damage the equipment and cause great losses to the users. The use of UPS power supply system can provide a stable voltage power supply for user equipment, ensure the normal operation of the equipment and prolong the service life.

3. The protective effect of surge

Usually Huawei UPS power supply system has a cutting-edge discharge design to absorb surge, avoid affecting the efficiency and life of the equipment due to surge problems, and provide protection for the equipment.

4. Protection of high and low voltage.

When the utility voltage is high and sometimes low, the voltage regulator (AVR) in the UP power supply keeps the utility voltage in a safe range that can be used to ensure the normal operation of the equipment. When the high and low voltage exceeds the usable norm, the UPS power supply system will start the battery power supply to ensure the continuous operation of the equipment.

5. Harmonic distortion protection.

When the power is transmitted to the user through the transmission and distribution line, the voltage waveform is distorted and the fundamental current changes to produce harmonics. Harmonics will affect the use of the equipment, through the UPS power supply can provide a stable and high-quality power supply for the equipment, effectively improve the operating efficiency and life of the equipment.

6. Stabilizing frequency action

The frequency is the cycle in which the electricity changes every second, and the 50Hz is 50 cycles per second. The change of rotational speed caused by the sudden change of user power consumption during the operation of municipal power generator will make the converted power frequency uncertain. The power converted by UPS power supply can provide a stable frequency to ensure the normal operation of instruments and equipment.

7. Instant protection

Municipal power sometimes has voltage upwelling and sag or instantaneous voltage drop, which will affect the accuracy of the equipment, and in serious cases, it will damage the precision equipment and cause users to suffer losses. Huawei's UPS power system can provide a stable voltage to protect the equipment.

8. the effect of suppressing transverse mode and common mode noise.

The transverse mode noise is generated between the hot wire and the neutral wire, and the common mode noise is generated between the hot wire, the neutral wire and the ground wire. Invisible power problems are difficult to prevent, endangering instruments and equipment all the time, causing losses to users. UPS power supply escorts the instrument and data to ensure the normal operation of the equipment and prolong the service life of the equipment.
