Oxygen, thanks to a suitable sizing of the power components and a remarkable response speed (
The energy required is taken directly from the network.
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.
The use of the double conversion technology guarantees the insulation from the disturbances and the distortions of the network and, together with the help provided by the electrolytic capacitors, makes it possible to build machines for high power loads.
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 they can work with or without the neutral wire.
Oxygen can operate with different input and, consequently, output voltage (380V or 415V) from the nominal one (400V).
The main components are:
The user interface is created using a multilingual «touch panel» (10″); through the selection menu, it is possible to display electrical values and set the operating parameters of the stabilizer.
It is also possible to communicate with the electronic component via the RS485 serial bus using the Modbus RTU protocol.
The standard cabinet is metallic with RAL9005 color and IP21 protection degree.
