Unlike other UPS types that are activated only during power outages, online UPSs can operate continuously. It consists of three main components: rectifier, battery and inverter. The rectifier converts the incoming AC power into DC power to charge the battery. The inverter then converts the DC power back to AC power, providing a stable current to connected devices. Therefore, even if the main power supply fails, there is a seamless transition to battery power, preventing operational interruptions.

Why use UPS in industry?
Continuous power supply

Online UPS systems provide continuous, consistent power to connected equipment, regardless of the quality of the utility power. This is accomplished by continuously drawing power from the battery and using it to provide clean, stable power to the load. This prevents downtime, data loss and equipment damage due to power fluctuations.

Zero transfer time
One of the main advantages of an online UPS is zero transfer time during a power outage. When a power failure occurs, the transition from mains power to battery power is instantaneous because the load is always running on the inverter. This is critical in an industry where even the slightest disruption can result in significant losses.

Voltage and frequency regulation

Online UPS systems adjust voltage and frequency. They mitigate voltage sags, surges and frequency changes that can damage sensitive equipment. This feature is critical in industries where electronic components are highly sensitive to such fluctuations.

Isolation from surges

Online UPS systems provide galvanic isolation, which means the load is isolated from the incoming utility power. This isolation prevents surges, spikes, and electrical noise from reaching connected devices, protecting them from potential damage.

Battery management and redundancy

Online UPS systems are equipped with advanced battery management functions. They continuously monitor the health of the battery, recharge it when needed, and provide information about its status. Additionally, many online UPS systems offer scalable redundancy options, where multiple UPS units are connected in parallel to provide increased backup power capacity and system reliability.

Remote monitoring and management

Many modern online UPS systems have built-in communications capabilities that enable remote monitoring and management. This allows IT staff to monitor UPS status, perform diagnostics, and even initiate shutdown procedures if necessary. This feature is especially valuable in industries that require centralized control.
