The Victron Cyrix-ct 12/24V-120A battery combiner (MPN CYR010120011R) is a high-performing microprocessing-controlled relay that automatically switches batteries parallely when a certain predefined voltage is reached (which shows that the battery is charged).It separates the batteries when voltage falls below the trickle charge value (which shows that one of the batteries is discharged). Cyrix battery combiners are an ideal replacement for common isolators. Their main characteristic is that there is nearly no voltage loss.That means that the AC-generator's or battery charger's output voltage does not need to be increased. Important details: 120A constant current 180A peak-current (5s) 12V/24V operation voltage (auto-detection) MPN: CYR010120011R Intelligent battery monitoring to prevent unwanted switchingA battery combiner (also called voltage-controlled relay or split-charge relay) disconnect batteries when there is a short but high-ampere load. Sometimes a battery bank is not connected because its DC-voltage instantly falls below the disconnection-threshold. The Cyrix-ct 12/24's software does more than only connecting or disconnecting depending on the battery voltage and with a certain time-delay. It observes the general tendency (voltage goes up or down) and only returns earlier measures if the tendency turns within a certain period of time.Time-delay is depending on how much the voltage deviates from the tendency.

As there is barely any voltage loss an increase of the charging voltage of battery charger or generator is not needed for compensation. Prioritizing of the starter batteryNormally the AC-generator is connected directly to the starter battery. The supply battery or thruster battery on a boat and others are connected via a Cyrix. Only when the starter battery has reached a certain voltage the other batteries are connected for parallel charging. Bidirectional voltage measuring and power supplyThe Cyrix measures the voltage values of connected battery groups. It therefore reacts only if the supply battery is charged via a battery charger.The Cyrix has a double power supply. It also works if one of the batteries does not have enough voltage for Cyrix-operation. To avoid unwanted switching during installation or after unplugging the battery connector it will not switch when one of the battery connection falls under 2V (12V battery) or 4V (24V battery). Parallel connection in case of an emergency (Start Assist)The Cyrix can also be activated via a button (stays activated for 30s). Additionally there's a button for parallel connection of the batteries. This comes in handy when the starter battery is empty or defective.

The Victron Cyrix-i 12/24V-400A (MPN CYR010400000) is an advanced battery combiner the prevents unwanted switching during current distribution. Some battery relays perform separation procedures when there are high currents. It is also possible that a big but empty battery group can't be connected because voltage would fall below the switch-off threshold.The Cyrix-i's software does not work with voltage values or time intervals. Instead it regards the trend (voltage/time) and only reacts when the trend changes within a certain interval. The time delay is proportional to the trend's voltage deviation.Additionally up to 4 different switching/time settings can be adjusted. Important features: constant output: 400A max. peak current (1s): 1000A operation voltage range: 24/48V (auto-adjustment) MPN: CYR010400000 Auto-voltage-range-setting 12/24V and 24/48VThe Cyrix-i recognizes the voltage automatically. No voltage lossThe Cyrix-i battery control is an alternative to isolation diodes. As there is barely any voltage loss an increase of the charging voltage of alternator or generator is not needed for compensation. Prioritizing of the starter batteryNormally the alternator is connected directly to the starter battery. The supply battery or thruster battery and others are connected via a Cyrix-i. Only when the starter battery has reached a certain voltage the other batteries are connected for parallel charging. Bidirectional voltage measurement and power supplyThe Cyrix-i measures the voltage values of connected battery groups. It therefore reacts only if the supply battery is charged via a battery charger.The Cyrix-i has a double power supply. It also works if one of the batteries does not have enough voltage for Cyrix-i operation. To avoid unwanted switching during installation or after unplugging the battery connector it will not switch when one of the battery connection falls under 2V (12V battery), 4V (24V battery) or 8V (48V battery). Parallel connection in case of an emergencyThe Cyrix-i can also be activated via a button (stays activated for 30s). Additionally there's a button for parallel connection of the batteries. This comes in handy when the starter battery is empty or defective. Delivery scope:1x Victron CYR010400000 Cyrix-i 12/24V-400A Battery Combiner1x Manual
