The ultra-fast Filax transfer switch from Victron Energy (MPN SDFI0000000) was developed to switch important or sensitive loads such as computers, industrial control devices or modern consumer electronics from one AC power source to another. The main power source is typically the mains, a generator or a shore connection. An inverter is usually used as an alternative source. With its switching time of less than 20 milliseconds, even sensitive loads continue to operate without interruption.
The Filax is not designed to supply household appliances with high power consumption, such as washing machines or electric motors.

Gap switching function

The Filax is a transfer switch with a bridging (non-bridging) switching function. The maximum time for switching loads is 16 ms. The load is normally supplied via the main power source and is switched to the alternative source in the following cases:

• The voltage of the main power source falls below the threshold value.
• The frequency of the main power source falls below the low frequency threshold or exceeds the high frequency threshold.

Switching back from the alternative power source to the main power source takes place as soon as the voltage and frequency values of the main power source are within the limit values specified for switching back for 30 seconds.

Technical data

• Max. Current: 16A
• Max. Max. time for switching: 16 ms
• Switching delay for switching back: 30 seconds
• Operating temperature range: -20°C - +50°C
• Humidity (non-condensing): Max. 95%
• Protection class: IP65
• Weight: 0.8 kg
• Dimensions: 120 x 255 x 75 mm

Installation

• Install the Filax in a dry and well-ventilated environment.
• The input cables from the generator / main power supply and the output cables to the devices must be connected in accordance with the wiring diagram.
• If a load of less than 850 watts is connected, the wire jumpers must be removed.
• The frequency (50 Hz or 60 Hz) is set by means of a jumper. If the jumper is not set for the frequency, the switching threshold values for the voltage are incorrect.
• Both inputs must be protected against current values of over 16 amperes.
• The front cover of the housing is attached using the four screws supplied.
• The Filax is now ready for use.
