Cyrix-Li-ct 12/24V-120A combiner

is an advanced contactor designed to optimize energy management in battery systems. It stands out intelligent microprocessor control, which ensures full automation of the process of disconnecting loads from the battery LiFePO4 The device can work with both VE.Bus BMS, What smallBMS, making it an extremely versatile solution in various power system configurations. A key feature of this model is the ability to parallel lead-acid batteries and LiFePO4, which increases the efficiency and stability of the power supply system.
Thanks to the ability to detect voltage at the level 13.4V (or as appropriate 26.8V for 24V systems), the device quickly responds to changes in the system, automatically disconnecting if a cell overvoltage or overheating is detected. Start-up assist function allows the relay to be closed for 30 seconds with a short pulse, which is particularly useful in critical situations. Cyrix-Li-ct It does not require the use of a reverse connection cable, which simplifies installation and use.
