What power interference problems does the UPS power supply solve?
1. Power outage protection - In the event of a momentary power outage, UPS will immediately convert the battery's DC power to AC power to continue supplying power.
2. 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. If the voltage is too low or too high to exceed the usable range, the UPS will convert the DC power of the battery into AC power to continue supplying power, in order to protect user equipment.
3. Waveform distortion processing - Due to the transmission of electricity to the client through transmission and distribution lines, the use of various machinery and equipment often causes distortion of the mains voltage waveform. This is because waveform distortion will generate harmonics to interfere with equipment and cause the temperature of power system transformers to rise. Generally, a distortion rate of less than 5% is required, while the distortion rate of general UPS designs is less than 3% to 5%.
4. Frequency stability - The frequency of a power supply is divided into two types: 50Hz/60Hz. The so-called frequency refers to the number of cycles that the power supply sine wave changes per second. 50Hz means it changes 50 times per second. The frequency of Taiwan's electricity is 60Hz, while in mainland China it is 50Hz. During the operation of the generator, sudden changes in the client's electricity consumption can cause fluctuations in speed, resulting in frequency drift of the converted power. The power converted by UPS can provide a stable frequency within a certain range.
5. Voltage Stability - The voltage of a city's power supply is easily affected by the quality of the power transmission line. Users closer to the substation have a higher voltage of about 230-240V, while users farther away have a lower voltage of about 180-210V. If the voltage is too high or too low, it can shorten the life of the user's equipment, and in severe cases, it can burn out the equipment. Using an online UPS power supply can provide stable power supply voltage, with voltage fluctuations of less than 2V, which can extend equipment life and protect equipment.
6. Suppress differential mode noise - Differential mode noise is generated between the live and neutral wires.
7. Suppress common mode noise - Common mode noise is generated between the live/neutral wire and the ground wire.
8. Surge protection - Generally, UPS will be equipped with surge absorbers or tip discharge designs to absorb surges and protect user equipment.
9. Instantaneous response protection - When the mains power is disturbed, it may sometimes cause voltage to bulge or sag or instantaneous voltage drop. The use of online UPS can provide stable voltage, making voltage fluctuations less than 2V, which can extend equipment life and protect equipment.
10. Monitoring power supply - With the intelligent communication interface and monitoring software of UPS, it can record the frequency and duration of power outages of the mains voltage to achieve power supply monitoring, and can arrange the UPS timed on/off schedule to save energy.
