VICTRON ENERGY – Cyrix-Li-Charge 24/48V-120A

R 1,221,00

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

The Cyrix-Li-Charge will connect a battery charger with 3 seconds delay:
– if the charge disconnect output of the VE.Bus BMS is high, and
– if it senses 13,7 V (resp. 27,4 V or 54,8 V) or more on its battery charger connection terminal, and
– if it senses 2 V or more on its battery terminal (the Cyrix will remain open if not connect to the battery).
The Cyrix-Li-Charge will disengage immediately whenever its control input becomes free floating, signalling cell over voltage or cell over temperature.

VICTRON ENERGY – Cyrix-Li-Charge 24/48V-120A

The Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.

The LiFePO4 battery: preventing cell under voltage, overvoltage and over temperature

The first line of protection is cell balancing. All Victron LiFePO4 batteries have integrated cell balancing.
The second line of protection consists of:
– shut down of the load in case of imminent cell under voltage, and
– shut down or reduction of the charging current in case of imminent cell over voltage, high temperature (>50°C) or low temperature (<0°C).
The VE.Bus BMS is the core of the second protection line.However, not all loads or chargers can be controlled directly by the VE.Bus BMS. In order to shut down such loads or chargers several VE.Bus BMS controllable Cyrix switches are available.
