Filax-2: the ultra-fast transfer switch
Filax has been designed to switch sensitive or critical loads, such as computers, industrial control or modern leisure equipment, from one AC source to another.
The priority source is generally the network, a generator or shore power. The alternative source is usually a converter.
With a switching time of less than 20 milliseconds, the sensitive loads will continue to operate without interruption.
The Filax is not intended to power large household appliances, such as washing machines or electric motors.
Open transition transfer
The Filax is an open transition transfer switch (BBM transfer).
The maximum charge transfer time is 16 ms.
The load is generally supplied by the priority source, and it is transferred to the alternative source, if:
The priority source voltage drops below the threshold value.
The frequency of the priority source drops below the threshold value for the low frequency, or increases above the threshold value for the high frequency.
The inversion of the transfer from the alternative source to the priority source begins when the priority source has operated within the reverse switching limits of voltage and frequency for 30 s.
