Why online UPS can meet power backup needs
Understanding Online UPS
The critical systems of organizational infrastructure cannot go down. It’s just that simple, the battery backup advantage of UPS systems ensures they won’t do this. When a conventional power supply fails or the voltage drops below a sustainable level, UPS can maintain power flow, ensuring that you can safely maintain important assets. In addition to protecting electronic devices from various AC power fluctuations, online UPS systems can also provide uninterrupted power to loads.
UPS systems are often described as the “heart” of IT organizations and are key applications in many industry sectors. The healthcare, finance, and education industries rely on the accessibility of data and records, and even brief power outages can have significant and expensive impacts on sensitive devices.
In order to cope with the risk of power outages, many enterprise server rooms are almost always equipped with online UPS systems. The duration of additional power supply required in the event of a malfunction determines which battery backup solution is most suitable for the system and data.
The UPS system is divided into three different topology structures, each with different power and characteristics:
Backup power supply
Essentially, it is a power outage/repair type UPS. The backup power supply is the most basic type of UPS topology, and in the event of voltage drops, surges, or power outages, the backup power supply will use a battery backup power supply. If the input mains voltage deviates from the safe voltage level, the UPS will automatically switch to DC battery power and then convert to AC power to operate the connected device. These systems are typically composed of batteries to provide short-term power, rectifiers or chargers to maintain voltage, inverters to provide power during normal load periods, and static switches to automatically transfer loads between mains and inverters. Suitable for consumer electronics, home computers, and security systems.
Online interactive
UPS technology can correct slight power fluctuations without switching to the battery. This type of UPS is equipped with an autotransformer that can regulate low voltage and overvoltage, enabling it to handle voltage drops and voltage surges. The online interactive model is also suitable for consumer electronics, gaming systems, personal computers, and entry-level to mid-range servers. Online interactive UPS systems are an ideal choice for protecting non critical task equipment, typically used in offices and IT cabinets.
Online or dual conversion
The UPS system can provide clean, consistent, and almost perfect performance regardless of the input power condition, thereby minimizing power outages. Dual conversion is the “king” in UPS, which converts input AC power into DC power, and then converts it back into AC power. These systems always operate on fully isolated DC power and have zero conversion time because they never need to switch to this power source.
The advantages of online dual conversion systems
Dual conversion UPS systems are designed to protect critical task IT equipment and are typically used for data center installations, high-end servers, and large-scale telecommunications installations.
Online or dual conversion UPS has advantages over other UPS solutions as it provides always online connectivity and zero transmission time for devices. Internal static bypass ensures that in the event of a major UPS failure, we will retain online functionality and critical loads during downtime caused by maintenance and replacement.
