Victron Energy - 230V/50Hz Filax 2 Automatic Transfer Switch

Victron Filax 2: Ultra-Fast Automatic Transfer Switch for 240V Systems

Seamless Power Continuity for Critical Electronics

The Victron Filax 2 is an advanced automatic transfer switch engineered to provide rapid, reliable changeover between two alternating current (AC) sources. Designed specifically for sensitive electronics, it ensures that computers, industrial control systems, and modern entertainment equipment continue operating without disruption during a power source transition. By monitoring the priority source, which is typically mains power, a generator, or shore power, the unit will seamlessly shift the load to an alternate source, such as a battery inverter, the moment the primary supply fails or fluctuates.

Precision Open Transition Changeover

Operating as an open transition, or "break before make" transfer switch, this unit executes a load transfer in less than 16 milliseconds. This ultra-fast switching time is critical for preventing resets or data loss in sensitive microprocessor-based equipment. The load is normally powered by the priority source. If the priority voltage drops below a specific threshold, or if the frequency deviates outside acceptable high or low limits, the changeover switch immediately activates the alternate source.

To prevent rapid toggling between power supplies during intermittent faults, the system incorporates a smart reverse transfer mechanism. The load will only revert to the priority source once it has operated within safe voltage and frequency limits for a continuous 30 seconds.

Engineered for Caravans, Marine, and Industrial Use

Whether you are configuring a 240V changeover switch for a caravan solar system, managing marine shore power connections, or securing remote industrial controls, this unit delivers exceptional reliability. Its robust ABS enclosure features IP65-rated cable glands to protect internal connections from dust and moisture, making it highly resilient in demanding mobile environments. Clear front-panel LED indicators provide immediate visual feedback regarding the active power source and any detected faults.

Please note that this transfer switch is specifically optimised for critical and sensitive loads. It is not intended to supply high-power household appliances with massive startup surges, such as washing machines or heavy-duty electric motors. Both inputs must be protected by appropriate circuit breakers rated no higher than 16 amps.

Key Features

• Ultra-fast transfer time: Less than 16ms changeover ensures continuous operation of sensitive digital loads.
• Smart reverse transfer: A 30-second delay verifies priority source stability before switching back.
• Selectable frequency: Easily configurable for 50Hz or 60Hz systems via an internal jumper plug.
• Robust environmental protection: Features an IP65-rated cable entry system and durable ABS casing.
• High capacity: Supports up to 16 Amps of current across both priority and alternate inputs.
• Status monitoring: Integrated LEDs for priority source, alternate source, and fault diagnostics.

Secure and Straightforward Integration

Designed for surface mounting, the compact enclosure includes pre-drilled side flanges for a secure fit in tight utility spaces. Dedicated terminal blocks for Phase, Neutral, and Earth connections on all inputs ensure an organised and safe electrical installation. For loads operating below 850 Watts, internal wire bridges can be easily removed to optimise performance.
