An Online Uninterruptible Power Supply (Online UPS) is a type of power protection device that provides continuous, high-quality electrical power to connected devices, ensuring that they remain operational even in the event of power disruptions or outages. Here are the key features and functionalities of an Online UPS:
Double Conversion Technology:Online UPS systems use a double conversion process. Incoming AC power is first converted to DC power, and then an inverter converts it back to AC power with a consistent voltage and frequency. This ensures a clean and stable power supply to connected equipment.
Constant Battery Charging:The UPS continuously charges its internal batteries, ensuring they are ready to provide power instantaneously in the event of a power outage.
Zero Transfer Time:In the event of a power interruption, an Online UPS seamlessly switches to battery power without any transfer time. This instantaneous transition prevents connected devices from experiencing any disruption.
Online UPS systems isolate connected equipment from power fluctuations, spikes, and surges. The double conversion process filters out any irregularities in the incoming power, providing a stable output.
Voltage Regulation:Online UPS systems regulate both voltage and frequency, ensuring that connected devices receive a constant and optimal power supply.
Battery Backup:Online UPS units include a battery backup system that provides power during outages. The size of the battery bank and the runtime it can offer depend on the UPS capacity and the power requirements of connected devices.
Parallel Redundancy (Optional):Some high-end Online UPS systems offer parallel redundancy, allowing multiple UPS units to operate in parallel. This provides additional reliability and load-sharing capabilities.
LCD/LED Display:Many Online UPS models include a display panel (LCD or LED) that provides real-time information about the UPS status, battery level, input/output voltage, and load.
Communication and Monitoring:Online UPS units often come equipped with communication ports (such as USB, RS-232, or SNMP) for connecting to computers or network management systems. This enables remote monitoring, configuration, and management of the UPS.
Scalability:Online UPS systems are scalable, allowing users to add additional battery packs or UPS units to increase the backup runtime or overall capacity.
Applications:Online UPS systems are commonly used to protect critical equipment such as servers, data centers, medical devices, telecommunications equipment, and other sensitive electronics.
