120A 12V-24V Cyrix-CT intelligent battery combiner - Victron Energy

Description

Intelligent battery control to prevent unwanted switching.

The Cyrix-ct 12/24 is a battery coupler that goes beyond simply connecting and disconnecting based on battery voltage and a set time delay. It also takes into account the general voltage trend (rising or falling) and only reverses a previous action if the trend has reversed for a certain period of time. This prevents unwanted switching due to excessive loads or sudden voltage drops.

Long bolts allowing connection of more than one power cable

The Cyrix-ct 12/24-120 features 13 mm bolts, allowing more than one power cable to be connected at the same time for more convenient installation.

Overheat protection (due to prolonged overload, for example)

The Cyrix-ct 12/24 is designed to shut down in case of overheating due to prolonged overload, and it will automatically restart after cooling down, thus ensuring protection against thermal runaway risks.

12/24 V auto sensing

The Cyrix-ct 12/24 is capable of automatically detecting the system voltage, whether it is a 12 V or 24 V system, making it versatile and easy to use in different battery configurations.

No voltage loss

Cyrix battery couplers are an excellent alternative to diode splitters, as they have very little voltage loss, thus eliminating the need to correct alternator or battery charger output voltages.

Starting battery priority

When you have an electrical system installed in your vehicle or boat, the alternator is directly connected to the starter battery. This battery is also used to power other batteries, such as the service battery and possibly other batteries, using Cyrix battery couplers.

When the Cyrix detects that the starter battery reaches a certain 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. Thus, it can also close when the service battery is charged by a battery charger, for example. The Cyrix-ct 12/24 has a dual power supply and will also close if the voltage on one of the batteries is too low to operate the Cyrix. To prevent unwanted operation during installation or if a battery has been disconnected, the Cyrix-ct 12/24 will not close if the voltage on either of the two battery connections is below 2 V (for a 12 V battery) or 4 V (for a 24 V battery)

Emergency parallel connection (StartAssist)

The Cyrix can also be engaged manually by pressing a push button (the Cyrix remains engaged for 30 seconds) or by using a switch to connect the batteries in parallel. This can be very useful in emergency situations when the starter battery is discharged or damaged, thus allowing you to continue using other batteries to power your electrical devices.
