Filax 2: the ultra-fast transfer switch
The Filax has been designed to switch critical or sensitive loads, such as
computers, industrial controls or modern entertainment equipment from one AC
source to another. The priority source typically is the mains, a generator or
shore power. The alternate source typically is an inverter. With its switching
time of less than 20 milliseconds sensitive loads will continue to operate
without disruption. The Filax is not intended to supply high power household
equipment like washing machines, or electric motors.
Open transition transfer
The Filax is an open transition (break before make) transfer switch. The
maximum load transfer time is 16ms. The load is normally supplied by the
priority source, and is transferred to the alternate source if:
- The voltage of the priority source drops below the threshold value.
- The frequency of the priority source drops below the low frequency threshold value, or increases beyond the high frequency threshold value.
Reverse transfer from the alternate source to the priority source is initiated
when the priority source has operated within the voltage and frequency reverse
switching limits during 30s.
Installation
• Install the Filax in a dry, well-ventilated area.
• The input cables from the generator/mains, the inverter and the output
cables to the appliances should be
connected according to the wiring diagram.
• If a load of less than 850 Watts is connected, then the wire bridges should
be removed.
• The frequency (50Hz or 60Hz) is set with a jumper. 50Hz no jumper placed.
60Hz jumper placed (see photo)
If the jumper is not set for the frequency the voltage switching threshold
levels will be incorrect.
• Both inputs must be protected against current levels higher than 16 amps.
• The front of the casing is attached using the four supplied screws.
• The Filax is now ready for use.
