Intelligent battery monitoring to prevent unwanted switchingSome battery combiners (also called voltage controlled relay, or split charge relay) will disconnect a battery in case of a short but high amperage load. A battery combiner also may fail to connect a large but discharged battery bank because the DC voltage immediately drops below the disengage value once the batteries are connected.The software of the Cyrix-ct 12/24 does more than simply connect and disconnect based on battery voltage and with a fixed time delay. The Cyrix-ct 12/24 looks at the general trend (voltage increasing or decreasing) and reverses a previous action only if the trend has reversed during a certain period of time.The time delay depends on the voltage deviation from the trend. (for Battery Combiners with multiple engage/disengage profiles, please see the Cyrix-i 400).Long bolts to allow connection of more than one power cableCyrix 12/24-120: 13 mm (M6) Cyrix 12/24-230: 16 mm (M8)Protection against overheating (due to a long duration overload e.g.)The Cyrix will disengage in case of excessive contact temperature, and reengage again after it has cooled down.LED status indication (Cyrix 12/24 230 only)LED on: engaged LED 10 s flash: disengagedLED 2 s flash: connecting LED 2 s blink: disconnectingLED 0,25 s blink: alarm (over temperature; voltage > 16 V; both batteriesPropertiesProtection Category: IP54Country of Manufacture: MalaysiaManufacturer Part Number: CYR010120011RWeight (kg): 0.11Dimensions: H46 x W46 x D80mmBrand: Victron EnergyControl Cable Included (Length 1 m): NoLED Status Indication: NoStart Assist: Yes (Cyrix remains engaged during 30 seconds)Cranking Rating (5 seconds): 180AVoltage: 12/24Warranty: 5 Years.
