The bulk phase is followed by the absorption phase. n BV approval Bureau Veritas is a French classification society for shipping, passenger vessels and some large yachts. The requirements in terms of safety and functionality are stringent and approval is required by many insurance companies. Most Mastervolt equipment exceeds BV’s rigorous standards. n Cable losses A loss of voltage resulting from the resistance of the cable. The losses also depend on the current flow. n 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. All Mastervolt equipment exceeds these rigorous standards. n 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. n Combi A device that combines a battery charger, an inverter and a transfer system in one. n 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. C 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. n Current The flow of electrons through a circuit. Electric current is measured in amps. n Cycle The theorectical discharging of a battery from 100 % to 0 %, and recharging back from 0 % to 100 % in one cycle. Twice discharging to 50 % and fully recharging is also one cycle, as is four times discharging to 75 % and fully recharging again. This is all theory however: In practice a battery is discharged not more than 50 %. n CZone ® A CZone system decentralises the DC power distribution system, locates circuit control and protection modules closer to loads to shorten cable runs and reduce the size of conductors, significantly decreasing the cost and weight of the electrical wiring harness. The CZone system replaces complex wiring with a single data wire. n Digital Switching Digital Switching is a Mastervolt innovation that radically simplifies installation, configuration, control and monitoring of onboard electrical systems. This CAN-based platform is proven in the automotive industry and is fully compatible with most A-brand navigation systems. It offers you a range of luxurious and comfortable options, including remote control. n DIP switch A tiny switch usually found on a printed circuit board and used to set the various functions of Mastervolt equipment. n Direct current (DC) Current that only flows in one direction, such as that in a battery, solar panel, alternator or battery charger. n DNV-GL approval Det Norske Veritas is a Norwegian classification society for professional shipping and offshore activities. The requirements in term of safety and functionality are very strict, and approval is required by many insurance companies. Most Mastervolt equipment easily satisfies DNV-GL’s stringent standards. Germanischer Lloyd is a German classification society for professional marine vessels. The requirements in terms of safety and functionality are very strict and this approval is often necessary for insurance purposes. n Earth The electric no-load potential, also called reference potential. The negative pole of a battery is often connected to the steel chassis of a vehicle or boat, which then serves as the earth. In US English the term grounding is used. n Earth leakage switch Monitors the onboard supply for electrical leakage, switching it off when leakage exceeds 30 milli-amps. An earth leakage switch protects you against an electric shock in the event of contact with a live component. n Efficiency The efficiency of a power source is expressed in percentage terms (%). A device with an efficiency of 90 %, for instance, has 100 % power at the beginning and 90 % at the end. The 10 % that is lost is primarily transformed into heat. The higher the efficiency of an inverter, the longer the batteries will last. n Electrolyte The liquid in batteries, composed of a mixture of sulphuric acid and water. Its specific gravity is 1.280 in a charged battery and 1.100 in a discharged one. TECHNICAL BACKGROUND D E 146
