Cyrix-Li-load 24 / 48V-120A

is a technologically advanced contactor from a renowned brand Victron Energy, designed to protect LiFePo4 batteries. Its main task is automatic load disconnection from the battery to protect against excessive discharge. The contactor operates under the control of a microprocessor that ensures precise management of the load disconnection and reconnection process. Thanks to its compatibility with energy management systems such as VE.Bus BMS and smallBMS The Cyrix-Li-Load 24/48V-120A provides reliable and stable operation in any installation. This product can be used to disconnect 12V, 24V, and 48V DC loads, making it an extremely versatile tool for a variety of applications. The contactor is optimized for use with batteries that require high level of protection against damage, ensuring longer battery life and system security.
A unique feature of this device is its third line of defense for LiFePO4 batteries. If the battery voltage drops to a critical level, the Cyrix-Li-Load will disconnect the loads, thus protecting the cells from further discharge. When the battery voltage returns to an appropriate level, the device will automatically attempt to reconnect the loads, which can happen up to three times in one minute. However, if the voltage does not increase, the Cyrix will remain off until the battery reaches the minimum required voltage, indicating that the charging process has begun. intelligent load management not only protects batteries, but also optimizes their performance.
Safety and reliability These are the priorities that underlie the Cyrix-Li-Load. In addition to standard protective functions, such as over-discharge prevention, the device protects batteries against overheating, low temperatures, and overvoltage. It can also be combined with additional protection modules, such as BatteryProtect, which further increases the level of safety in high-demand installations. The contactor also features low current consumption, making it extremely energy-efficient.
