Comutação Digital

- Digital Switching is an innovation that radically simplifies installation, configuration, control and monitoring of onboard electrical systems.

Cos phi or power factor

- Specifies in AC systems the degree to which current is out of phase with voltage: The lower this value, the larger the discrepancy and lower the efficiency. In a heating element, for instance, the current is in phase with the voltage, so the cos phi is 1. In a motor, however, there is a divergence, and cos phi tends to be 0.8 or sometimes 0.6. The lower the cos phi, the more current is required to supply a given amount of power.

Combi

- A device that combines a battery charger, an inverter and a transfer system in one.

Charge Voltage

- Voltage used to charge batteries. On average, it amounts to 14.4 volt or 28.8 volt during the absorption phase and 13.25 volt and 26.5 volt during the float phase, both at 25 °C.

CE marking

- Marking placed on a product by manufacturers or importers to declare that it meets EU safety, health and environmental requirements. These requirements are derived from European product directives, which have been incorporated into the national legislation of most EU member states. The CE mark therefore shows compliance with a law and is not informal advice. It should be visible on the outside of equipment and suppliers have to make available a declaration stating which requirements of the CE marking the equipment meets.

Charge Absorption Phase

- The second stage in a modern 3-step+ charging process. Batteries are charged from around 80% up to 100 % during this stage. Voltage is somewhat lower than the gas voltage of the battery, which is 2.4 volt per cell at 20 °C (or 14.4 volt for a 12-volt and 28.8 volt for a 24-volt battery). The absorption phase follows the bulk phase and is, in turn, followed by the float phase.
