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

is an advanced contactor created by Victron Energy, which provides exceptional precision in managing the charge of LiFePO4 batteries. This contactor operates thanks to a microprocessor that automatically disconnects the charger from the battery when necessary, protecting the system from damage and excessive load. Thanks to the possibility of control via Ve.Bus BMS or smallBMS, the user has complete control over the charging process. Its versatility makes it ideal for installations where precise charging control is crucial. Cyrix-Li-Charge ensures smooth switching between battery charge states, which increases its efficiency and extends battery life.
The operation of this device is simple but effective. Cyrix-Li-Charge The charger will connect to the battery with a 3-second delay if certain conditions are met, such as the voltage at the charger terminal exceeding 13.0V (for 12V systems). In the event of an overvoltage or excessive cell temperature, the device will immediately disconnect, protecting the system from damage. Once conditions stabilize, the Cyrix will reconnect the charger, continuing charging safely. Additionally, the device is equipped with LEDs that visually indicate its operating status, making it easy to monitor the charging process.
