Cyrix-Li-load 24 / 48V-230A

presents a high-quality contactor Cyrix-Li-load 24/48V-230A, the ideal solution for load management in battery systems LiFePo4 This intelligent, microprocessor-controlled component is designed to automatically disconnect loads when battery voltage drops, thereby protecting battery life. It can be controlled either by VE.Bus BMS, What smallBMS, which makes it extremely versatile and compatible with various energy management systems.
Cyrix-Li-load 24/48V-230A acts as a third line of protection for batteries LiFePo4 When the battery voltage drops below a critical level, the device disconnects the load to prevent further discharge. If the voltage returns to normal, Cyrix-Li-load will automatically turn on the load after 30 seconds. This mechanism can make up to three attempts to reconnect. In the event of a further voltage drop, the device remains off until the battery reaches a charge level above 13 V, 26 V or 52 V (depending on the system) for at least 30 seconds, which signals the resumption of the charging process. It is also worth mentioning that alternatively, you can use BatteryProtect, which is characterized by extremely low energy consumption, which is an important advantage in power management.
Thanks to advanced protection functions, Cyrix-Li-load protects batteries against excessive discharge and overheating. This device is designed to operate with DC loads with voltages 12V and 24V and intensity 230 A, ensuring reliability in demanding conditions. Control is carried out using a system VE.Bus BMS or smallBMS, which enables flexible management of the device's operation. Additionally, built-in LEDs indicate the contactor's operating status, making monitoring and diagnostics easier.

Three levels of protection for your system

First line of battery protection LiFePo4 is a cell balancing system that prevents undervoltage, overvoltage, and overheating of cells. All batteries Victron LiFePo4 have integrated balancing mechanisms, which guarantees long-term and safe operation. The second line of defense includes automatic load shutdown when the voltage approaches a critical level and reduction of the charging current in the event of cell overvoltage or extreme temperatures. In a situation where the system VE.Bus BMS cannot directly control some loads, Cyrix acts as an additional safety switch, providing full control over the energy system.
