In case of over temperature due to high ambient temperature and/or due to excessive current, the Cyrix-ct will open. It will resume normal operation after cooling down.
Prioritising the starter battery
In a typical setup the alternator is directly connected to the starter battery. The accessory battery, and possibly also a bow thruster and other batteries are each connected to the starter battery by Cyrix battery combiners. When a Cyrix senses that the starter battery has reached its connect voltage it will engage, to allow for parallel charging of the other batteries.
Bidirectional voltage sensing
The Cyrix senses the voltage of both connected batteries. It will therefore also engage if for example the accessory battery is being charged by a battery charger.
Intelligent battery monitoring to prevent repeated switching
The software of the Cyrix-ct 120 does more than simply connect and disconnect based on battery voltage and with a fixed time delay. The Cyrix-ct 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.
12/24 and 24/48 Volt auto ranging
The Cyrix-ct will automatically adjust to a 12V, 24V, 48V system.
