Detailed description
Detailed description
The Victron Energy Cyrix-ct 12/24V-120A intelligent battery combiner is a microprocessor-controlled relay designed to automatically connect batteries in parallel. It closes the connection when one battery reaches a preset voltage, indicating it is charging, and disconnects the batteries when the voltage drops below the float level, indicating discharge. This system is an alternative to diode isolators, offering the advantage of no voltage drop, preventing the need to increase alternator or charger output voltages. It automatically adapts to 12V and 24V systems.
Features and performance
The Cyrix-ct 12/24V-120A includes temperature protection. If overheating occurs due to high ambient temperature or excessive current, it will open and resume normal operation after cooling. In a standard setup, the alternator is connected to the starter battery. The Cyrix-ct allows the service battery—and potentially other batteries such as a bow thruster battery—to be connected to the starter battery. Once the starter battery reaches its closing voltage, the Cyrix-ct closes to enable parallel charging of the other batteries.
Intelligent and bidirectional monitoring
The Cyrix-ct combiner measures the voltage of both connected batteries. It will close if the service battery is charged by an external battery charger. The Cyrix-ct 12/24V-120A provides a continuous current of 120 A. Its current draw is less than 4 mA when open. It has an IP54 protection rating.
