Off-Line Technology • Voltage & frequency dependant (VFD)

Passive standby topology (off-line) is a frequently used UPS topology for protecting against blackout. In normal mode, the UPS supplies power to the application directly from the mains, filtered but without active conversion. The battery is charged from the mains. In the event of a power cut or fluctuation, the UPS delivers stable power from the battery. The advantages of this topology are low cost and adequacy for office environments. Passive standby topology is not suitable if the power supply is of lower quality (industrial sites). Due to the lower protection level, this type of technology is not recommended/produced by Vision UPS.

Average switching time to battery mode : 10ms

Line-interactive Technology • Voltage independant (VI)

Line interactive topology is mostly used for enterprise networks and IT applications. It protects from blackout, undervoltage and overvoltage. In normal mode, the device is controlled by a microprocessor that monitors the quality of the supply and reacts to fluctuations. A voltage stabilizer (AVR) is enabled to boost or reduce the supply voltage to compensate the input voltage fluctuations. The main advantage of this topology is that it enables compensation of under- and overvoltage without using the batteries.

Average switching time to battery mode : 4-10ms

On-Line Technology • Voltage & frequency independant (VFI)

Double conversion topology (on-line) is a basis for UPS designed for continuous power protection from all eight power problems: power failure, undervoltage, overvoltage, frequency variation, voltage harmonics, voltage distortion, high-frequency transient, (power surge with galvanic isolation). It ensures a consistent quality of power supply regardless of disturbances in the incoming mains. The output voltage is entirely regenerated by a sequence of AC to DC conversion followed by DC to AC conversion in order to create a 100% clean power. Double conversion UPSs can be used with any type of equipment as there is no switching when changing over to battery power.

Switching time to battery mode : 0ms
