The Victron Cyrix-i 12/24V-400A Intelligent Battery Combiner is a microprocessor-controlled heavy-duty relay designed to automatically connect batteries in parallel when one reaches a predefined voltage, indicating charging, and disconnect them when the voltage drops below the float level, indicating discharging. This device serves as an excellent replacement for diode isolators, offering virtually no voltage loss, thereby eliminating the need to adjust the charging voltages of alternators or battery chargers.
- Automatic Voltage Detection: The Cyrix-i automatically detects system voltage, accommodating both 12/24V and 24/48V systems.
- Intelligent Battery Monitoring: The device monitors the voltage of both connected batteries, ensuring optimal charging and discharging cycles.
- No Voltage Loss: Unlike diode isolators, the Cyrix-i ensures virtually no voltage loss, maintaining the efficiency of the charging system.
- Prioritization of Starter Battery: In typical installations, the alternator is directly connected to the starter battery. The Cyrix-i engages when the starter battery reaches the connect voltage, allowing parallel charging of other batteries.
- Bidirectional Voltage Sensing: The Cyrix-i senses the voltage of both connected batteries, engaging when either battery is being charged, such as when the accessory battery is charged by a battery charger.
- Emergency Parallel Connection: The device can be manually engaged via a push button or switch to connect batteries in parallel for 30 seconds, useful in emergencies when the starter battery is discharged or damaged.
