Designed to integrate seamlessly with a \u003cstrong\u003eVE.Bus BMS\u003c\/strong\u003e, this relay acts as a critical second line of defence, automatically disconnecting loads when cell voltages approach unsafe levels. By preventing deep discharge, it helps extend battery cycle life and maintain system reliability in mobile, marine, and off-grid applications.\u003c\/p\u003e\n\u003cp\u003eUnlike generic voltage-sensitive relays, the Cyrix-Li-load responds directly to the BMS control signal, ensuring precise, cell-level protection rather than relying solely on overall battery voltage. This targeted approach reduces the risk of premature cell failure and the associated downtime or replacement costs.\u003c\/p\u003e\n\u003ch3\u003eHow It Works: BMS-Driven Load Management\u003c\/h3\u003e\n\u003cp\u003eThe Cyrix-Li-load engages when its control input receives a high signal (approximately battery voltage) from the VE.Bus BMS, allowing normal load operation. If the BMS detects an imminent cell under-voltage, it releases the control input, causing the relay to disengage and isolate the loads. This immediate response prevents further discharge and protects the cells.\u003c\/p\u003e\n\u003cp\u003eAfter disconnection, battery voltage often recovers slightly. The Cyrix-Li-load will attempt to re-engage after a 30-second delay. If the under-voltage condition persists, it will try up to three times before locking out. To reset, the battery voltage must rise above 13 V (26 V for 24 V systems) for at least 30 seconds, indicating that charging has resumed. This intelligent logic avoids nuisance cycling while ensuring loads are only reconnected when safe.\u003c\/p\u003e\n\u003ch3\u003eKey Features at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e230 A continuous rating\u003c\/strong\u003e at 12 V or 24 V, suitable for high-demand DC loads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect BMS integration\u003c\/strong\u003e via included 1-metre control cable for precise cell-level protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow power consumption\u003c\/strong\u003e (\u0026lt;4 mA when open) to minimise drain on the battery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP54 protection\u003c\/strong\u003e against dust and water spray, ideal for engine rooms and exposed installations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED status indicator\u003c\/strong\u003e for at-a-glance monitoring of relay state and alarm conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact, lightweight design\u003c\/strong\u003e (65 x 100 x 50 mm, 0.27 kg) for flexible mounting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM8 stud terminals\u003c\/strong\u003e (approx. 5\/16\") accept heavy-duty lugs for secure, low-resistance connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBuilt for Demanding Environments\u003c\/h3\u003e\n\u003cp\u003eWith an IP54-rated enclosure, the Cyrix-Li-load resists dust ingress and splashing water, making it suitable for use in marine engine compartments, vehicle under-bonnet installations, and other harsh settings.
