Online UPS is a type of UPS that supplies power to the AC load through the Rectifier and Inverter Combo in normal operation and uses an inverter to supply AC power during a power failure. Therefore, the output power supply always stays ON and there is no need for switching. It provides isolation between main supply and load. Since inverter is always ON, the quality of load voltage is free from distortion.

Online UPS systems are used in mission critical applications such as for medical equipments – MRI / CT Scan etc, for large networks and for industrial applications such as CNC machines.

Digital Technology: Microprocessor based digital control ensures pure and perfect sinewave output delivering accurate voltage and clean power. It increases speed and efficiency of power conversion and facilitates communication interface between the machine and the user.

Double Conversion Topology (With Galvanic Isolation): This UPS topology provides complete isolation from the incoming distribution system and the load at the UPS output. Continuous protection of load is provided from the Inverter, whether it originates from AC-input supply or the battery. Wide input voltage tolerances, precise regulation of the output voltage and frequency and a no-break transfer to bypass mode are the other main benefits with double conversion.

Active power factor correction: The advanced technology used in the rectifier section with active power factor correction reduces power consumption by 30%. It reduces input current as well as voltage harmonics and helps to considerably downsize the generator or utility power rating. It has a soft-start feature to avoid in rush current.
