What are the interference factors of UPS power supply

1. Voltage sag: refers to one or more cycles where the voltage is below 80% to 85% of the effective value of the rated voltage. Mainly caused by the start-up of nearby heavy equipment or the start-up of electric machinery.

2. Frequency offset: refers to a change in the mains frequency exceeding 3Hz. This is mainly caused by the unstable operation of emergency generators or power supply from sources with unstable frequencies.

3. Power interruption: A power interruption is a state of no power for more than one cycle. The causes include circuit breaker tripping on the line, interruption of mains power supply, and power grid failure.

In summary, in order to ensure the correct operation of computers, prevent the loss of real-time control signals, and ensure the safe operation of equipment, people have put forward increasingly strict requirements for the quality of power supply. The main purpose of developing UPS technology is to improve the dynamic response to output load faster and better. Obviously, adopting advanced high-frequency technology results in the fastest dynamic response speed and better performance. Some high-frequency machines have poor quality due to cost savings, outdated production conditions, and design. In order to keep up with market trends, improve efficiency, and be more environmentally friendly and energy-efficient, it is very necessary to choose a well-known and trustworthy modular UPS brand.
