No voltage loss

The Victron Cyrix-ct 12/24V-230A Intelligent Battery Combiner - Isolator is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one battery has reached a preset voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or both batteries are being discharged). Cyrix battery combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.

Prioritising the starter battery

In a typical setup the alternator is directly connected to the starter battery. The accessory battery, and possibly also a bow thruster and other batteries are each connected to the starter battery by Cyrix battery combiners. When a Cyrix senses that the starter battery has reached its connect voltage it will engage, to allow for parallel charging of the other batteries.

Bidirectional voltage sensing

The Cyrix senses the voltage of both connected batteries. It will therefore also engage if for example the accessory battery is being charged by a battery charger.

Intelligent battery monitoring to prevent repeated switching

The software of the Victron Cyrix-ct 12/24V-230A Intelligent Battery Combiner - Isolator does more than simply connect and disconnect based on battery voltage and with a fixed time delay. The Cyrix-i looks at the general trend (voltage increasing or decreasing) and reverses a previous action only if the trend has reversed during a certain period of time. The time delay depends on the voltage deviation from the trend.

12/24 Volt auto ranging

The Cyrix-i will automatically adjust to a 12V or 24V system.
