The Victron Cyrix-Li-Charge 12/24V-120A, also known as the CYR010120430, is an advanced battery combiner designed by Victron Energy. This essential component facilitates the efficient connection of a battery charger with your system, ensuring optimal charging performance while safeguarding battery health. With features like delayed engagement and automatic disconnection, this device manages your battery’s charging needs effectively, preventing cell overvoltage and ensuring reliability in different temperature conditions.
The Cyrix-Li-Charge initiates a connection to a battery charger with a three-second delay if specific voltage and BMS conditions are met. This feature maximizes charging efficiency and prevents unnecessary battery strain.
This device disengages the charger instantly when control input indicates a risk, such as cell overvoltage or high temperature, thus protecting the battery’s integrity.
The system will automatically reconnect the charger after a transient voltage alarm resets, ensuring seamless operation without manual intervention. This adaptability helps maintain battery functionality.
The Cyrix-Li-Charge will disconnect after one hour of engagement to test if the battery charger is still functional, adding a layer of protection against potential overcharging.
In cases of minimal or zero discharge current, the device remains engaged, keeping the battery voltage stable and safeguarding against inappropriate disconnection.
The Cyrix-Li-Charge works in conjunction with the VE.Bus BMS, enhancing your electrical system’s safety by managing the charging process. This integration prevents battery damage through automatic control of charger connections based on battery condition.
The device connects to a charger based on input from the BMS, battery voltage levels, and a constant voltage at the charger’s terminal, optimizing energy management.
It has the ability to immediately disconnect when potential risks are detected, safeguarding the battery from excessive voltage and temperature problems.
The Cyrix-Li-Charge incorporates a relay that manages voltage surges, reducing impact on the system when the connection is stopped unexpectedly due to safety alerts.
