400A 12V-24V Cyrix-i-intelligent Battery Combiner Victron Energy

Description

New: an intelligent battery control to prevent unwanted switching.
Some battery combiners disconnect the battery in case of short but high voltage charging. A battery combiner may also fail to connect a large discharged battery bank because the DC voltage immediately drops below the release value once the battery is disconnected.
The Cyrix-i program does more than simply connect and disconnect based on battery voltage and a set delay time. The Cyrix-i takes into account the general trend (voltage increase and decrease) and reverses a previous action only if the trend has reversed for a certain period of time. The delay time depends on the voltage deviation from the trend. In addition, 4 engagement time profiles can be selected (see back of page)

Automatic 12/24 V and 24/48 V Range

The Cyrix-i automatically detects the system voltage.

No Voltage Drop

Cyrix battery combiners are an excellent replacement for diode splitters. Its main feature is the absence of voltage drop, thus avoiding the need to correct alternator or battery charger voltages.

Starting Battery Priority

In a typical installation, the alternator is directly connected to the starting battery. The service battery, and possibly a bow thruster and other batteries are all connected to the starting battery via Cyrix battery combiners. When a Cyrix detects that the starting battery has reached its engagement voltage, it closes to allow parallel charging of the other batteries.

Bidirectional Voltage Sensing and Power Supply from Both Batteries

The Cyrix monitors the voltage of both connected batteries. Therefore, it will also engage when, for example, the service battery is charged by a battery charger.
The Cyrix-i has a dual power supply. It will also close if the voltage on one of the batteries is too low to run the Cyrix.
In order to avoid unwanted operation during installation or if a battery has been disconnected, the Cyrix-i 12/24 - 100 will not close if the voltage on one of the connections of these two batteries is below 2 V (12 V battery), 4 V (24 V battery) or 8 V (48 V battery).

Emergency Parallel Connection

The Cyrix can also be engaged with a push button (the Cyrix remains engaged for 30 s) or with a switch to connect the batteries in parallel manually.
This can be very useful in an emergency when the starting battery is discharged or damaged.
