The Cyrix-ct intelligent battery combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged. 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.
It will analyse 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. Sensing the voltage of both connected batteries, the Cyrix will engage if for example the accessory battery is being charged by a battery charger.
The Cyrix-ct 12/24 also has a dual power supply and will close if the voltage on one battery is too low to operate the Cyrix but will not close if the voltage on one of the two battery connections is lower than 2V (12V battery) or 4V (24V battery).
