Ten basic functions of UPS uninterruptible power supply

1) Voltage stability --- The mains voltage is easily affected by the quality of the power transmission line. The user voltage near the substation is higher by about 130 ~ 120V, and the user voltage farther from the substation is lower by about 100 ~ 90V. If the voltage is too high or too low, the life of the user equipment will be shortened, and the equipment will be burned in severe cases. The use of online UPS can provide a stable voltage power supply, and the voltage change is less than 2V, which can extend the life of the equipment and protect the equipment.

2) Power failure protection --- In case of an instant power failure, the UPS uninterruptible power supply immediately converts the battery DC power into AC power and continues to supply power.

3) High and low voltage protection --- When the mains voltage is too high or too low, the built-in voltage regulator (AVR) of the UPS will make appropriate adjustments to keep the mains voltage within the usable range. Above the usable range, the UPS will convert the battery DC power to AC power and continue to supply power to protect user equipment.

4) Frequency stability --- The mains frequency is divided into two types of 50Hz / 60Hz. The so-called frequency is the period that changes every second. 50Hz is 50 cycles per second. The frequency of Taiwan's mains is 60Hz, and the mainland is 50Hz. When the generator is running, the speed change caused by the sudden change in the power consumption of the client will cause the frequency of the converted power to fluctuate. The power converted by the UPS uninterruptible power supply can provide a stable frequency.

5) Waveform distortion processing-As the power is transmitted to the client via the power transmission and distribution lines, the use of various machinery and equipment often causes the distortion of the mains voltage waveform, because the waveform distortion will generate harmonics * equipment and will cause the power system Transformer temperature rise, generally requires distortion rate <5%, general UPS design distortion rate <3%.

6) Monitoring power supply --- With the intelligent communication interface and monitoring software of UPS, it can record the mains voltage frequency and frequency of power outage time and number to achieve the power supply monitoring, and can arrange the UPS uninterruptible power supply timing switch-on schedule to save energy.

7) Suppress common mode noise-Common mode noise is generated between the hot / neutral and ground lines.

8) Suppression of transverse mode noise-transverse mode noise is generated between the hot and neutral lines.

9) Surge protection --- Generally UPS uninterruptible power supply will install surge absorber or tip discharge design to absorb surge to protect user equipment.

10) Instantaneous response protection --- When the mains power is received, sometimes the voltage may protrude or sag or instantaneous voltage drop. Using an online UPS can provide a stable voltage, so that the voltage change is less than 2V, which can extend the life of the equipment and protect the equipment.
