Cyrix-Li-ct 12/24V-230A combiner

is an innovative and extremely reliable brand contactor Victron Energy, designed to safely and automatically disconnect loads from a LiFePO4 battery. Thanks to the use of an advanced microprocessor, this device operates automatically, minimizing the risk of battery damage and ensuring longer system life. Furthermore, Cyrix-Li-ct can be controlled using Ve.Bus BMS or smallBMS, which allows for optimal energy management in more complex installations.
The device operates by automatically connecting and disconnecting lead-acid batteries and LiFePO4, ensuring their cooperation in 12V and 24V systems. This contactor switches on when it detects a voltage of 13.4V (or 26.8V in the case of 24V) at one of the terminals, which means the battery is ready for connection. Cyrix-Li-ct disconnects immediately in potentially dangerous situations, such as overvoltage or cell overheating. Furthermore, the device offers a jump-start function that activates the relay for 30 seconds with a short pulse.
Cyrix-Li-ct 12/24-230A does not require the use of a reverse connection cable, which makes its installation simpler and more intuitive. Victron Energy made sure that the user could rely on the device in all conditions by equipping it with class protection IP54, which ensures resistance to dust and moisture. The device is also extremely lightweight – it weighs only 0.27 kg, and its compact dimensions of 65x100x50 mm mean it fits in any installation space.
