It disconnects non-essential loads when the battery reaches a low-voltage threshold, protecting the battery from deep discharge. Rated at 120A continuous, it suits a wide range of off-grid and marine DC load circuits.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRated at 120A continuous current, suitable for substantial DC load circuits at 24V or 48V.\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled switching logic monitors battery voltage and disconnects loads at a programmable low-voltage threshold.\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for lithium battery chemistries, where accurate low-voltage disconnect is critical to cell longevity.\u003c\/li\u003e\n  \u003cli\u003eAutomatic reconnection when battery voltage recovers to the set reconnect threshold, requiring no manual intervention.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.12 kg, allowing installation in tight battery enclosures or distribution panels.\u003c\/li\u003e\n  \u003cli\u003eCompatible with 24V and 48V DC systems, covering a broad range of off-grid, marine and vehicle installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Cyrix-Li-load operates by continuously monitoring the battery terminal voltage. When voltage drops to the low-voltage disconnect threshold, the relay opens and isolates the connected loads from the battery. This prevents the battery from being discharged beyond safe limits, which is particularly important for lithium chemistries where over-discharge can cause permanent cell damage or trigger battery management system shutdowns.\u003c\/p\u003e\n\n\u003cp\u003eUnlike a simple fuse or manual isolator, the Cyrix-Li-load responds automatically to battery state without any user input. When the battery recovers, the relay closes again and restores power to the loads. This makes it well suited to unattended installations where manual intervention is not practical, such as remote off-grid cabins, liveaboard vessels or vehicle auxiliary systems.\u003c\/p\u003e\n\n\u003cp\u003eThe 24\/48V dual-voltage compatibility means a single unit covers both common off-grid system voltages. At 120A, it handles high-current load circuits including inverters, pumps and lighting banks without requiring an additional contactor or relay.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CYR020120450\u003c\/li\u003e\n  \u003cli\u003eContinuous current rating: 120A\u003c\/li\u003e\n  \u003cli\u003eSystem voltage: 24V or 48V DC\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.12 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076022275\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-voltage load disconnect in lithium battery off-grid systems at 24V or 48V.\u003c\/li\u003e\n  \u003cli\u003eMarine auxiliary load protection on liveaboard or commercial vessels with lithium house banks.\u003c\/li\u003e\n  \u003cli\u003eVehicle and motorhome auxiliary circuits where battery protection is required without manual switching.\u003c\/li\u003e\n  \u003cli\u003eRemote off-grid cabins and telecoms installations where unattended operation is essential.\u003c\/li\u003e\n  \u003cli\u003eLoad shedding in solar storage systems to protect the battery during periods of low charge.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Cyrix-Li-load 24\/48V-120A intelligent load relay\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstallation should be carried out by a qualified electrician or experienced systems integrator familiar with DC battery systems. Ensure the unit is correctly rated for the total connected load current and that appropriate fusing is installed on all battery connections.
