Oxygen is a SAG compensator, suitable for dealing with sudden, big and short duration voltage drops (commonly known as SAGs).
The use of the double conversion technology guarantees the protection from the disturbances and the distortions of the network and, together with the help provided by the electrolytic capacitors, makes it possible to build products for high power loads.
The voltage compensation on the buck/boost primary winding is performed by IGBT static switches controlled by a microcontroller. The microcontroller system monitors the output voltage and determines the opening or closing of the IGBT contacts ensuring the best regulation.
Oxygen, thanks to a suitable sizing of the power components and a remarkable response speed (<3 msec) is able to confront voltage drop(SAG) with maximum duration one minute.
Current models are able to cover network’s voltage drop to 50% of the nominal value (-50%).This SAG Compensator can operate with a load variation range for each phase from 0 to 100%, it is not affected by the power factor of the load and it can works with or without the neutral wire (on request). Oxygen can operate with different inputs and, consequently, output voltage (380V or 415V) than the nominal one (400V).
