Cyrix-Li-load 12 / 24V-230A

is a modern contactor that ensures optimal load management of the LiFePO4 battery. Thanks to an advanced microprocessor, the device automatically disconnects loads, protecting the battery from excessive discharge. A key element of this solution is the ability to control it using systems VE.Bus BMS or smallBMS, making the Cyrix-Li-Load not only versatile but also a safe choice for users requiring precise control over their energy system.
One of the most important features of the Cyrix-Li-Load is its ability to disconnect a load when the battery voltage drops below a specified level. This process occurs automatically when the battery voltage becomes floating, meaning that no other load is connected. After disconnection, if the battery voltage rises to a suitable level, the Cyrix makes three attempts to reconnect the load. If these attempts are unsuccessful, the device remains off until the voltage rises to at least 13V (for 12V systems) or 26V (for 24V systems) and remains there for 30 seconds, indicating that the battery is being charged. This functionality minimizes the risk of battery damage and ensures longer system life.
High quality and reliability devices make Cyrix-Li-Load 12/24-230 is an excellent choice for installations using LiFePO4 batteries, including photovoltaic systems, campers and yachts. The device can alternatively be used with BatteryProtect, offering exceptionally low power consumption. When the Cyrix is off, current consumption is less than 4 mA, further enhancing its efficiency. Combined with its compact dimensions (65 x 100 x 50 mm) and low weight (0.27 kg), this contactor is ideal for applications where space saving and reliability are key.

Multi-Stage LiFePO4 Battery Protection

is the third line of defense in protecting LiFePO4 batteries. The first line is integrated cell balancing system in Victron LiFePO4 batteries, which prevents overvoltage, undervoltage and cell overheating. The second line of protection is VE.Bus BMS, which automatically disconnects loads when the cell voltage drops to a dangerously low level, or reduces the charging current in the event of overvoltages. Cyrix-Li-Load 12/24V-230A It acts as an additional guard, ensuring that loads are immediately disconnected when the voltage drops below a safe level. This allows users to be confident that their energy system is operating safely.
For complete protection, the Cyrix contactor works with VE.Bus BMS systems, a key element of energy management. In the event that the VE.Bus BMS is unable to control all loads or chargers, Cyrix-Li-Load steps into action, automatically disconnecting loads not directly supported by the BMS. This versatility makes this product an ideal choice for complex installations where full load control is a priority.
