Mastervolt Powerbook 2023 EN

n E-Mark This regulation is the type-approval test for European automotive electronics. It includes a variety of testing including RF immunity and emissions, transient immunity and emissions. It now includes a requirement for burst, surge, harmonics & flicker and provides advice and requirements for electrical vehicles. Most Mastervolt battery chargers, inverters and Lithium Ion batteries comply with these requirements. n EMC Short for Electro-Magnetic Compatibility, EMC indicates how much, if any, electromagnetic interference a device may produce and whether it is sensitive to electromagnetic interference from the outside. A good example is that of a battery charger and a microwave oven. The microwave is not allowed to produce more interference than determined by the EMC standard, and the battery charger may not be affected by the interference generated by the microwave. Naturally, the opposite also holds true. Requirements in terms of EMC are established within the CE framework. Mastervolt equipment exceeds these strict requirements. n E-Propulsion Electrical propulsion is growing in popularity and is compulsory in an increasing number of sailing and nature areas. A hybrid version is also available, allowing you to choose whether to sail using a diesel engine or electric motor. n Float phase The final step in a modern 3-step+ charging process. Although the batteries are fully charged during this phase, they receive a maintenance charge, while the onboard DC circuit is supplied with power. Charge voltage is 2.25 volt per cell or 13.25 volt for 12-volt batteries and 26.5 volt for 24-volt ones at an ambient temperature of 25 °C. n Forced inverter A function on the Mass Systemswitch. At the push of a button, a part of the onboard consumers are powered from the batteries via the inverter, while the battery charger stays connected to power. The power intake of the battery charger can be regulated via the system panel, up to the point where the maximum for the AC fuse has been reached. The advantage of this system is that heavy-duty consumers such as hair dryers are powered via the inverter and cannot therefore overload the AC fuse. When such consumers are connected to the inverter, consumption from the batteries is usually higher than the battery charger can supply. This is rarely a problem as major consumers are usually used for a short time and the consumption measured in Ah tends to be low. After the consumer has been switched off the battery charger will recharge the battery automatically. n Frequency The number of times per second that alternating current changes direction, expressed in hertz (Hz). n Galvanic isolation A situation where two circuits are electrically connected without their grounding or earth coming in contact. Galvanic isolation is best achieved by means of a transformer. n Gas voltage The voltage level at which a battery starts producing gas. At at an ambient temperature of 20 ºC, the gas voltage is 2.4 V per cell or 14.4 V for a 12 V battery and 28.8 V for a 24 V one. n Gel battery Batteries where the electrolyte (mix of water and sulphuric acid) is absorbed in a gel. As they are entirely maintenance- free and rarely produce gas, Gel batteries can be fitted anywhere. Extra gas extraction is not necessary. Gel batteries are highly suitable for lighting and as onboard service batteries, and can be charged very quickly thanks to their special construction. With normal use the lifespan of a 12-volt Gel battery is between six and seven years. For the 2 volt traction Gel version, 15 years is not uncommon. A Gel battery is very suitable for (deep) cycle usage. n Hertz (Hz) Unit that measures frequency, i.e. the number of times per second that an alternating current (AC) changes direction. In Europe this is 50 Hz, and in the USA 60 Hz. F G H TECHNICAL TERMS n 3-Step+ charging A modern charging technology that has been extended with an extra step in Mastervolt equipment, the Plus phase. The three steps are: n Bulk, where the charger supplies maximum power. n Absorption, during which the charger delivers maximum charge voltage and the battery is charged from around 80 % to 100 %. n Float, used for battery maintenance and delivering power to connected equipment. The ‘plus’ phase is an automatic one-hour bulk phase once every 12 days when the battery is not being used. 147
