Victron Energy Cyrix CT Intelligent Leisure Battery Combiner - 12/24V - 120A

Victron Cyrix-ct: Smart Battery Combiner for Reliable Power Management

The Victron Cyrix-ct 12/24 is an intelligent battery combiner that goes beyond basic voltage-controlled relays. It prevents unwanted battery disconnection and ensures optimal charging for your various electrical systems in campervans, caravans, motorhomes, and boats.

Overcoming Limitations of Traditional Battery Combiners

• Prevents Disconnect from Short, High-Current Loads: Unlike some basic combiners, the Cyrix-ct won't disconnect your batteries due to temporary high current spikes, ensuring uninterrupted power supply.
• Connects Even Deeply Discharged Batteries: The Cyrix-ct factors in voltage trends, not just instantaneous voltage. This allows it to connect even heavily discharged batteries that might cause a brief voltage drop upon connection in a standard system.

Intelligent Voltage Monitoring and Connection

• Trend-Based Decision Making: The Cyrix-ct analyzes the overall voltage trend (increasing or decreasing) before taking action. It only reverses a previous action (connect/disconnect) if the trend changes significantly within a specific timeframe.
• Time Delay Based on Voltage Deviation: The delay before reconnection after disconnection is adjusted based on the severity of the voltage deviation from the trend. This ensures the system stabilizes before reconnection.

Additional Features:

• 12/24V Auto Ranging: Automatically adapts to your system voltage (12V or 24V).
• Minimal Voltage Loss: Virtually no voltage drop compared to diode isolators, maintaining optimal charging efficiency.
• Prioritizes Starter Battery: Connects the starter battery first, ensuring it's fully charged before supplying auxiliary batteries.
• Bidirectional Voltage Sensing: Senses voltage of both batteries, allowing connection if the auxiliary battery is being charged by a separate source.
• Dual Power Supply: Operates even if one battery voltage is low.
• Safety Measures: Prevents accidental operation during installation or with a disconnected battery (voltage threshold below 2V or 4V).
• Emergency Start Assist: Manual button or switch allows for parallel connection of batteries for jump-starting in case of a dead starter battery.

By eliminating the shortcomings of traditional battery combiners, the Victron Cyrix-ct offers a smarter and more reliable solution for managing your multi-battery system.
