UPS Uninterruptible Power Supply Applications and Principles
UPS power solutions include models ranging from backup UPS, online UPS, online interactive UPS, modular UPS, and other monitoring products.
The company enjoys a high level of recognition and acceptance within the industry.
Application Scope
Primarily applied in industries such as government, finance, telecommunications, electricity, transportation, manufacturing, and more.
The operational model of the Beijing agent for online UPS systems (On-Line UPS), which provide uninterrupted power supply, is that "mains power and electrical equipment are isolated; the mains power does not supply electricity directly to the electrical equipment."
Instead, upon reaching UPS, it is converted to direct current, which then splits into two paths—one for charging the battery.
Another path converts the current back to alternating current, powering the electrical equipment. In the event of unstable municipal power supply or power outages, the battery switches from charging to supplying power until the municipal power supply returns to normal, at which point it resumes charging.
UPS is fully involved throughout the entire process of electricity consumption.
Its advantages include the output waveform, which is identical to the utility power and is a sine wave, as well as its purity with no noise and immunity to fluctuations in utility power.
Powerful for "inductive loads," such as electric fans.
Under the condition that UPS output power is sufficient, it can power any device that uses municipal electricity.
Backup and Working Principle
Backup UPS, also known as Off-Line UPS, is a "backup" type of UPS that supplies power directly from the main power supply to the electrical equipment.
Battery Charging (Normal Mode): In the event of unstable utility power quality or a power outage, the utility circuit will automatically disconnect.
The direct current from the battery will be converted to alternating current to handle the power supply task (Battery Mode).
"UPS will only step in to provide power during power outages until the municipal power is restored. However, the alternating current from the DC-to-AC conversion is a square wave."
Limited to supplying power to capacitive loads, such as computers and monitors.
