The main function of Uninterruptible Power Supply is to provide backup power in case of power interruption or voltage abnormality, ensuring the continuous operation of critical equipment and data security. The following is a detailed analysis of its core functions, application scenarios, and working principles:

A.main function:

1.Zero interruption power supply is quickly switched through built-in batteries (mostly maintenance free lead-acid batteries) to avoid equipment shutdown or data loss caused by grid failures.

2.Suitable for scenarios with high requirements for power stability, such as computers, servers, medical equipment, etc.

B.Power protection:

1.Voltage stabilization and filtering functions can isolate power grid pollution (such as voltage fluctuations, surges, harmonics) and extend equipment life.

2.Prevent precision instruments (such as medical imaging equipment, industrial control systems) from being damaged due to power issues.

C.Compliance and Security:

1.Medical, financial, industrial and other fields must comply with regulatory requirements (such as operating rooms must be equipped with UPS).

2.Prevent production accidents or legal disputes caused by power outages.

D.Application scenarios:

1.Specific purpose: To ensure the continuous operation of servers and network equipment in data centers, and to prevent data loss or business interruption.

2.Medical facilities provide 24-hour uninterrupted power supply for life support equipment such as operating room monitors and ventilators.

3.The financial system ensures zero interruptions in trading and clearing systems, avoiding financial losses or regulatory penalties.

4.Industrial control protects automated production lines (such as PLCs and robots) from the impact of circuit breakers.

5.Power continuity for communication and transportation maintenance base stations, signal systems, and security monitoring.

E.Working principle:

1.Normal mode: The mains power is converted into DC power by a rectifier, which charges the battery and outputs pure AC power through an inverter.

2.Battery mode: When the mains power is interrupted, the battery is powered by the inverter, with a switching time of<4ms (online power supply).

3.Bypass mode: When the power supply is overloaded or faulty, it is directly supplied by the mains power (without voltage regulation function).

F.The function of Uninterruptible Power Supply:

1.Uninterruptible Power Supply: is it a backup power supply? 

2.Uninterruptible Power Supply achieves "zero interruption" power supply.

3. Uninterruptible Power Supply is the "power safety cabin" of the digital world.

G.Classification:

1.Online: Dual transformation architecture, optimal power quality (THD<3%), suitable for data centers.

2.Offline: Low cost, long switching time (5-10ms), suitable for personal computers.
