Victron Energy CYR010120011R Cyrix-ct 12/24V-120A intelligent battery combiner Retail

The Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage, and disconnects when the voltage decreases below float level. Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased. Read Full Description

Temperature protected

In case of over temperature due to high ambient temperature and/or due to excessive current, the Cyrix-ct will open. It will resume normal operation after cooling down.

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 Cyrix-ct 120 does more than simply connect and disconnect based on battery voltage and with a fixed time delay. The Cyrix-ct 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 and 24/48 Volt auto ranging

The Cyrix-ct will automatically adjust to a 12V, 24V, 48V system.
