Mastervolt DC-DC Converters - DC Master, Mac & Magic For 12V, 24V & 48V The voltage required for direct current (DC) can vary considerably onboard a yacht. A bowthruster or a winch often works at 24V, while navigation and communication equipment mostly requires 12V. By using a DC-DC converter, other voltages than applied in your basic system can be reached. They also ensure that all your onboard equipment has a stable power supply with the right voltage. DC Master series - Recreational and semi-professional use - Easy to install using included mounting bracket - Excellent price/performance ratio - More power available for two minute intervals, ideal for active marine telephone use - Supplied with mounting bracket, screws and fasteners Mac & Magic series - Professional use - Battery charger and dimmer function - Parallel connection - Adjustable output voltage - Voltage stabilisation for a longer lifespan of halogen lights, etc. The Magic models can regulate the voltage both up and down to ensure an optimal voltage stabilisation, even when the battery voltage fluctuates due to heavy loads. The galvanic isolation between input and output prevents disruptions to, for instance, communication equipment. Programmable via a desktop or laptop PC Remote control the Mac or Magic via your laptop or PC or configure your personal preferences. The device has a communication port and easy installation with a PC-Link and MasterAdjust software. 3-Step battery charger Connected to the 24V main battery, the converter can also be used as advanced 3-step chargers for 12/24V gel, AGM, wet or Lithium Ion batteries (Mac and Magic models only). Masterstrokes - No unnecessary heat development due to the use of smart electronics - Continuous output voltage - Easy to install Please note: - Choose the right input/output voltage - Do you require galvanic isolation? - Desired capacity Energy-saving dimmer function Many standard light dimmers convert part of the energy to heat and also lose unnecessary energy. The Mastervolt Mac and Magic converters regulate the power supply efficiently and without excessive heat build-up, up to 250 Watt for optimal safety (multiple Mac or Magic converters can be used for multiple lamps). Over 90% efficiency Advanced high-frequency technology with modern microprocessors ensures minimum power loss when switching from 24 to 12V and vice versa. If you have many power consuming devices on-board, the parallel use of several units allows capacities of 40, 60 or more amps. Solid connections Chrome plated brass connection block with screw terminal or chrome plated fast-on for DC in/out. Complete package DC Master All DC Master converters are supplied with mounting bracket, screws and fasteners. Mastervolt Mac Plus series Charging the service batteries on board of a vehicle or vessel can be challenging. Recharging tends to take a long time and batteries may not receive a full charge. This is a common problem found in boats, service vans, campers and trucks. Smart alternators and start/stop systems make the problem even worse. Traditionally, a service battery is linked to the starter battery by means of a charge relay. The starter battery is located close to the alternator and receives most of the charge current. However, the service battery is usually further away. Long cables cause voltage drop, leading to slow charging, resulting in failing appliances and premature failure of the battery. Modern, fuel efficient engines are equipped with smart alternators, following regulations such as Euro 5 and Euro 6. Instead of a constant output, smart alternators provide a variable voltage; after a brief charging period, voltage is reduced and the charging stops. Furthermore, the energy produced by regenerative braking leads to voltage peaks. Service batteries coupled in the traditional way will receive hardly any charge and may be damaged by these peak voltages. The Mac Plus is your battery?s best friend. It monitors your service battery and makes sure it?s always fully charged, maximising the lifetime of your battery. Features - Fast and safe charging during short trips. - Fanless design for silent operation. - Suitable for flooded, Gel, AGM and Li-Ion batteries (incl. LiFePO4). - Charges even fully depleted batteries. - Engine run detection protects starter battery. - Adjustable current limits to meet Euro 5/6 requirements. - Voltage stabilisation protects sensitive equipment, lights and loads. - Parallel operation to obtain charging capacities well over 100 Amps. - MasterBus for intelligent system monitoring and automation. - Temperature compensation and voltage sense for an optimal charging result. - E-mark certification for mobile applications. - Power supply mode. - Heavy duty connections for easy installation and quick set up via DIP switches. Applications - Boost charge voltage when service battery is located further from charging source or in systems with a smart alternator. When a stable power supply or different system voltage is needed.
