1. Power outage maintenance---In the event of a momentary power outage, the UPS power supply immediately converts the battery DC power into AC power to provide continuous power.
2. Voltage Surge Protection---When the mains voltage is too high or too low, the UPS power supply's built-in voltage regulator (AVR) will make appropriate adjustments to keep the mains voltage within a usable range. If the voltage is too low or too high and exceeds the usable range, the UPS will convert the battery's DC power to AC power to continuously supply power in order to protect the user's equipment.
3. Waveform Distortion Processing --- As electricity is transmitted to the customer through transmission and distribution lines, the use of various machines and equipment often causes distortion of the mains voltage waveform. Waveform distortion will generate harmonic interference to the equipment and will cause the temperature of the power system transformer to rise. Generally, the distortion rate is required to be <5%, and the distortion rate of a typical UPS is <3%.
4. Stable Frequency---Main power frequency is divided into two types: 50Hz and 60Hz. The so-called frequency is the cycle of change per second. 50Hz means 50 cycles per second. The frequency of mains power in Taiwan is 60Hz, while that in mainland China is 50Hz. When the generator is running, the sudden changes in the power consumption of the customer will cause the speed of the generator to change, which will cause the frequency of the converted power to drift. The power converted by the UPS can provide a stable frequency.
5. Stable Voltage – Mains voltage is easily affected by the quality of power transmission lines. Users closer to the substation have higher voltages, approximately 130-120V, while users farther from the substation have lower voltages, approximately 100-90V. Voltages that are too high or too low can shorten the lifespan of user equipment and, in severe cases, burn it out. Using an online UPS power supply can provide a stable voltage, with voltage fluctuations of less than 2V, which can extend the lifespan of equipment and facilitate equipment maintenance.
6. Suppress transverse noise---Transverse noise occurs between the front and the neutral line.
7. Suppress common-mode noise --- Total common-mode noise is generated between the front/neutral and ground lines.
8. Surge protection---Generally, UPS systems are equipped with surge absorbers or peak discharge designs to absorb surges and protect user equipment.
9. Instantaneous Response Maintenance---When the mains power is disturbed, voltage spikes, dips, or instantaneous voltage drops may occur. Online UPS power supplies can provide stable voltage, with voltage fluctuations of less than 2V, which can extend the life of equipment and facilitate equipment maintenance.
10. Power Supply Monitoring – The intelligent communication interface and monitoring software of the UPS power supply can record the frequency and timing of mains voltage outages to achieve power supply monitoring, and can also schedule the UPS power supply to turn on and off at set times to save energy.
