Victron Cyrix-ct 12/24V 120A Intelligent Battery Combiner

Description

No voltage lossThe Cyrix-ct 120 battery combiner 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 batteryIn 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 sensingThe 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 switchingThe software of the Cyrix-ct 120 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 rangingThe Cyrix-i will automatically adjust to a 12V or 24V system.Model Cyrix-ct 12/24-120Part # CYR10120011Continuous current120 AmpsMax alternator rating150 AmpsCurrent consumption when open4 mAEmergency startYes, 30sAuto ranging12/24 VoltsFor more information, see the Victron Cyrix-i Installation Manual.
