1). Voltage stability-the voltage of a mains is easily affected by the quality of the power transmission line. The voltage of users closer to the substation is about 130~120V higher, and the voltage of users farther away from the substation is about 100 lower ~90V, if the voltage is too high or too low, it will shorten the service life of the user's equipment, and it will burn the equipment when it is serious. Using an online UPS can provide a stable voltage power supply with a voltage change of less than 2V, which can extend the life of the equipment and protect the equipment.
2). Power outage protection---The UPS uninterruptible power supply will immediately convert the battery DC power supply into AC power and continue to supply power in the event of an instant power outage.
3). High and low voltage protection---When the mains voltage is too high or too low, the UPS built-in voltage regulator (AVR) will make appropriate adjustments to keep the mains voltage within the usable range, if the voltage is too low Or too high to exceed the usable range, the UPS converts the battery DC power supply to AC power to continue power supply to protect user equipment.
4). Frequency stability ---One mains frequency is divided into 50Hz/60Hz, the so-called frequency is the cycle of every second change, 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 sudden change of the power consumption of the client will cause the fluctuation of the rotation speed to make the frequency of the converted power drift. The power converted by the UPS uninterruptible power supply can provide a stable frequency.
5). Waveform distortion processing --- Because power is transmitted to the client via transmission and distribution lines, the use of various machinery and equipment often causes distortion of the mains voltage waveform, because the waveform distortion will generate harmonics* equipment and will cause When the temperature of the power system transformer is increased, the distortion rate is generally required to be <5%, and the distortion rate of the general UPS design is <3%. 6).Monitoring power supply---Cooperating with the intelligent communication interface and monitoring software of UPS can record the mains voltage frequency frequency outage time and times to achieve power supply monitoring, and can arrange the schedule of UPS uninterruptible power supply timing switch to save energy . 7). Suppression of common mode noise-a common mode noise is generated between the live wire/neutral wire and the ground wire. 8). Suppression of transverse mode noise-a transverse mode noise is generated between the live and neutral lines. 9). Surge protection---General UPS uninterruptible power supply will be installed with surge absorber or cutting-edge discharge design to absorb surge to protect user equipment. 10). Instantaneous response protection --- when the mains power is received, sometimes it will cause the voltage to protrude or sag or instantaneous voltage drop. Using an online UPS can provide a stable voltage, making the voltage change less than 2V, which can extend the life of the equipment and protect the equipment. Power inverter
