Cyrix-CT 12/24V 230A - Intelligent battery coupler - VICTRON ENERGY

Intelligent battery coupler Victron Energy Cyrix-CT 12/24V-230A

A robust relay between batteries connected in parallel, the Cyrix-CT (formerly Cyrix-i), a top-of-the-range separator coupler from Victron Energy, lets you recharge a 12V auxiliary battery using the energy produced by the alternator when your vehicle is started.

No voltage drop: a major advantage for the Cyrix-CT 230A

The Cyrix-CT battery coupler is distinguished by its almost total absence of voltage drop. This means you won't need to adjust the charging voltages of alternators or battery chargers, simplifying its use.

Intelligent control to prevent unwanted switching

The Cyrix CT 230A monitors the voltage levels of the two connected batteries while giving priority to the engine battery, ensuring that the vehicle can always be started. It will switch off if the voltage of one of the batteries is too low, thus decoupling the batteries and preventing the more charged battery from unintentionally discharging the other.

Thanks to its bi-directional current detection, the Cyrix-ct 12/24V will activate when the auxiliary battery is recharged by an external battery charger.

Overheating protection and LED indicators

Equipped with overheating protection, the Cyrix-CT deactivates in the event of excessive temperature and reactivates once it has cooled down. A series of LEDs clearly indicate the status of the device:

• LED on: activated
• LED on for 10 seconds: deactivated
• LED flashes every 0.25 seconds: alert
• LED flashes every 2 seconds: disconnected

Installation and compatibility

Self-adapting 12/24V system

The Cyrix-CT 230A automatically adapts to 12V or 24V systems, eliminating the need for complex manual settings. It is essential that your installation is in negative common to ensure optimal operation.

Extensive compatibility

This coupler is ideal for a variety of vehicles with :

• A vehicle complying with EURO 3 or EURO 4 standards
• An alternator of less than 230A

Emergency use (STARTASSIST)

In an emergency, the Cyrix-CT can be manually activated via a push button or switch to connect the batteries in parallel, which is very useful when the starter battery is discharged or damaged.

Recommendations for optimum installation

Connection instructions

Connect the negative pole of the Cyrix battery coupler to each battery. Make sure that the fuse is sized according to the cross-section of the cable used, never exceeding 230 A.
