Victron Energy - Cyrix-ct 12/24V-120A intelligent battery combiner Retail - CYR010120011R
Intelligent battery monitoring to prevent unwanted switching
Some 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 cable
Cyrix 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.
