It waits for the BMS signal to return high and verifies that the charger output is above 13.7V (12V system) or 27.4V (24V system). A 3-second delay ensures stability before re-engaging. If repeated faults occur, the delay extends to 10 minutes, preventing rapid cycling that could stress system components. Additionally, if battery voltage drops below 13.5V (27V for 24V) for an hour, the relay disengages to avoid unnecessary drain.\u003c\/p\u003e\n\u003ch3\u003eKey Features at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstant BMS-driven disconnection\u003c\/strong\u003e for overvoltage and over temperature protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e120A continuous rating\u003c\/strong\u003e at 12V\/24V, with 40A breaking capacity at 48V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic reconnection logic\u003c\/strong\u003e with progressive delays to prevent cycling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow power consumption\u003c\/strong\u003e (\u0026lt;4mA when open) ideal for energy-conscious systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact, robust design\u003c\/strong\u003e (46x46x80mm, 0.11kg) with IP54 protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in transient voltage suppression\u003c\/strong\u003e to protect against inductive spikes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClear status LED\u003c\/strong\u003e for quick operational diagnostics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSeamless Integration with Victron Energy Systems\u003c\/h3\u003e\n\u003cp\u003eThe Cyrix-Li-Charge is purpose-built for Victron's ecosystem, connecting directly to the VE.Bus BMS control output.

Ideal for marine vessels, large off-grid power setups, and commercial vehicles, this robust 400A relay automatically connects batteries in parallel when one has reached a preset charge voltage, and disconnects them when the voltage drops below the float level.\u003c\/p\u003e\n\u003cp\u003eUnlike traditional diode isolators, the Cyrix-i introduces virtually no voltage drop. This critical efficiency eliminates the need to increase the output voltage of alternators or battery chargers, ensuring maximum power delivery. The unit automatically detects either 24V or 48V system voltages, making it a highly versatile component for demanding electrical architectures.\u003c\/p\u003e\n\u003ch3\u003eIntelligent Trend-Based Monitoring\u003c\/h3\u003e\n\u003cp\u003eStandard battery combiners often struggle with short, high-current loads, disconnecting batteries prematurely if the system voltage dips temporarily. Conversely, they might fail to connect a heavily discharged battery bank because the sudden inrush current instantly pulls the voltage below the disengage threshold. The Cyrix-i solves these issues using intelligent software that monitors general voltage trends rather than reacting to sudden spikes or drops. It will only reverse a switching action if a voltage trend has reversed over a specified time period, which dynamically adjusts based on the severity of the voltage deviation. Installers can also select from four distinct switch timing profiles to suit specific system parameters.\u003c\/p\u003e\n\u003ch3\u003eBidirectional Sensing and Priority Charging\u003c\/h3\u003e\n\u003cp\u003eIn typical setups, the alternator connects directly to the starter battery. The auxiliary battery, along with heavy loads like bow thrusters, connects to the starter battery via the Cyrix combiner. The system prioritises the starter battery, only engaging parallel charging for auxiliary banks once the primary battery is adequately charged.\u003c\/p\u003e\n\u003cp\u003eFeaturing bidirectional voltage sensing, the unit also engages if the auxiliary battery receives a charge from an independent source, such as a solar array or mains battery charger. A dual power supply ensures the internal relay remains operational even if one battery's voltage drops significantly. To prevent unexpected activation during maintenance, fail-safes prevent engagement if connection voltages fall below critical levels (below 4V for 24V systems, or 8V for 48V systems).\u003c\/p\u003e\n\u003ch3\u003eBuilt for Emergency Preparedness\u003c\/h3\u003e\n\u003cp\u003eFor critical situations where a starter battery is heavily depleted or damaged, the system includes an emergency parallel connection feature. This start assist function can be triggered manually via a push button or remote switch, locking the relay closed for 30 seconds to allow engine starting directly from the house or auxiliary battery bank.\u003c\/p\u003e\n\u003ch3\u003eHardware Built for Professional Installations\u003c\/h3\u003e\n\u003cp\u003eThe physical design features heavy-duty metal studs to securely accommodate large gauge battery cables, sustaining optimal current flow under peak 400A loads.
