Description (from PDP, plain text)
Victron Energy ● Cyrix Series Victron Cyrix-ct 12/24V-120A Intelligent Battery Combiner Automatic Battery Parallel Charging & Protection | 12V/24V Auto-Ranging | 120A Continuous The Victron Cyrix-ct 12/24V-120A Intelligent Battery Combiner is a microprocessor-controlled heavy-duty relay designed for efficient battery management in 12V and 24V systems. It automatically connects batteries in parallel when one reaches a pre-set voltage, indicating it's being charged, and disconnects them when the voltage drops below float level, preventing discharge. This intelligent battery combiner offers a superior alternative to traditional diode isolators by ensuring virtually no voltage loss, eliminating the need to increase the output voltage of alternators or battery chargers. Its advanced software monitors voltage trends to prevent unwanted switching, even with large or discharged battery banks. KEY FUNCTIONALITY: Microprocessor-controlled heavy-duty relay for efficient, zero-loss automatic battery parallel charging. Key Features ▶ Microprocessor Controlled — Ensures precise and reliable automatic battery management. ▶ Zero Voltage Loss — Replaces diode isolators, delivering full charging voltage without efficiency loss. ▶ Intelligent Battery Monitoring — Advanced software prevents unwanted switching and handles large, discharged battery banks. ▶ 12/24V Auto Ranging — Automatically detects and adapts to either 12V or 24V system voltages. ▶ Bidirectional Voltage Sensing — Senses voltage from both connected batteries, allowing charging from either source. ▶ Overheating Protection — Disengages automatically in case of excessive contact temperature for enhanced safety. ▶ Start Assist Function — Allows manual parallel connection of batteries for 30 seconds in emergency situations. Technical Specifications Parameter Value Model Cyrix-ct 12/24V-120A Manufacturer Part Number (MPN) CYR010120011 SKU 792-CYR010120011 System Voltage 12V / 24V Auto-ranging Continuous Current Rating 120A Cranking Rating (5 seconds) 180A Current Consumption (Open) <4 mA Current Consumption (Closed, 12V) 220 mA Current Consumption (Closed, 24V) 120 mA Power Cable Bolt Size M6 (13 mm) Protection Category IP54 Dimensions (H x W x D) 46 x 46 x 80 mm Weight 0.11 kg Operating & Power Guidance Intelligent Software Logic The Cyrix-ct analyses voltage trends (increasing or decreasing) and only reverses a previous action if the trend has genuinely reversed over a period, preventing nuisance switching from short, high-amperage loads. Prioritising the Starter Battery In typical setups, the alternator charges the starter battery first. The Cyrix-ct engages to allow parallel charging of auxiliary batteries once the starter battery reaches its connect voltage. Dual Power Supply & Low Voltage Lockout The unit can operate even if one battery voltage is low. However, to prevent unexpected operation during installation or with deeply discharged batteries, it will not close if the voltage on either connection is below 2V (12V system) or 4V (24V system). Typical Applications Application Description Marine Vessels Efficiently manages charging of starter and service batteries from a single alternator. RVs & Campervans Ensures auxiliary leisure batteries are charged while the vehicle engine is running. Off-Grid Systems Connects multiple battery banks for charging from various sources. Commercial Vehicles Manages auxiliary power systems for equipment and accessories. Built-In Protection Functions The Victron Cyrix-ct 12/24V-120A incorporates several safety features for reliable operation: ▶ Overheating Protection: The unit will disengage if contact temperature becomes excessive due to prolonged overload and re-engage once cooled. ▶ Intelligent Switching Logic: Prevents unwanted disconnections caused by short but high-amperage loads, ensuring stable operation. ▶ Low Voltage Lockout: Prevents engagement if the voltage on either battery connection is below 2V (12V system) or 4V (24V system), safeguarding against unexpected operation. ▶ IP54 Protection: Offers protection against dust ingress and splashing water, suitable for various environments. Common Questions What is the primary function of the Victron Cyrix-ct 12/24V-120A Combiner? It automatically connects two battery banks in parallel for charging when a charge source is active and disconnects them when discharging, ensuring efficient power management without voltage loss. How does the Cyrix-ct differ from a standard diode isolator? Unlike diode isolators, the Cyrix-ct has virtually no voltage loss, meaning alternators or chargers do not need to compensate for voltage drop, leading to more efficient charging and faster battery replenishment. Can the Cyrix-ct be used for emergency starting? Yes, it features a 'Start Assist' function, allowing manual parallel connection of batteries via a push button or switch for 30 seconds, which is useful in emergency starting situations. Does the Cyrix-ct 12/24V-120A work with both 12V and 24V systems? Yes, this model is auto-ranging and automatically detects the system voltage, making it compatible with both 12V and 24V battery systems. Installation Notes Ensure the Cyrix-ct is mounted in a dry, well-ventilated area, away from flammable materials. Use appropriately sized cables and fuses for the 120A continuous current rating to prevent overheating and ensure safety. Always disconnect battery negative terminals before beginning installation to avoid short circuits. Follow Victron Energy's official wiring diagrams and safety guidelines provided in the product manual for correct connection. Professional installation is recommended for optimal performance and safety, especially in complex systems. Before You Buy Verify your battery bank voltages (12V or 24V) are compatible with the Cyrix-ct's auto-ranging capability. Confirm the 120A continuous current rating is sufficient for your charging sources (e.g., alternator) and the total current draw of your auxiliary battery bank. Consider the physical dimensions (46 x 46 x 80 mm) and mounting requirements for your specific installation space. Ensure you have all necessary cabling, terminals, and fusing to complete a safe and compliant installation. Specifications are based on manufacturer data and are subject to change. Always verify compatibility and installation requirements before purchase.
