Battery Chargers - IVO Smart / Mass Series

• IVO Smart

For professional and recreational use

Mastervolt introduces two new battery chargers: the IVO Compact 12/25-3 and 24/10-2. The models are fitted in a robust aluminum/Valox enclosure, suitable for marine, mobile and industrial use! Introduction to the market is expected for September 2004. Principal innovations:

• The powerful microprocessor, similar to the one used in the Mass range, can be programmed to any relevant protocol, utilizing the IVO Smart Wizard software, obtainable from the Mastervolt website. All models can be adjusted for use with gel, AGM or wet batteries by removing a jumper. This will also prepare the units for ‘forced float’ operation.
• New is the ‘memory function’, which prevents the charger starting a new 3-stage charge cycle if the supply voltage is interrupted. As a consequence, battery gassing will be eliminated.
• All models are equipped with a DC high/ low voltage and AC status alarm as standard, which can be programmed using the IVO Smart Wizard software.

12/25-3: ideal for marine and mobile systems

The 12/25-3 is fitted with a temperature controlled fan and is able to charge three batteries simultaneously with a maximum charge rate of 25 amps to two batteries. A third 3A output has to be connected to the starter battery. All types of batteries can be charged: gel cells, AGM or wet batteries; even a combination of both will charge correctly. Another important feature is the automatic compensation for low incoming shore power. Even at 180V AC, the charge current will be at maximum. All models are equipped with a LED status indicator displaying the stage of the charge cycle: bulk-absorption-float (battery fully charged). The 12/25-3 is also fitted with the ‘memory’ function, Mass temperature sensor, alarm functions, automatic voltage compensation and accessible via the IVO Smart Wizard software. Quality guaranteed Like all Mastervolt power electronic products the IVO Compact range is manufactured to ISO 9000-2001 standards and complies with CE, ABYC, E4 and Kema (similar to Tüv) and all relevant national standards. See our website for more details. All models are attractively packaged with a 4-language manual, an AC cable including plug, battery cables and two year unlimited world wide guarantee.

Communication: IVO Compact Data Control

The IVO Compact battery charger is delivered with an integrated communication interface as standard. This makes the system interactive with the option of reading the most essential information using your PC or laptop. All that is required to connect the IVO Compact with your computer is a communication cable and PC Link (adapter plug).

Suitable for global use

Smart battery chargers have a built-in autoranging function which allows connection to any electricity system in the world. The electricity grid in the Caribbean is usually 110V/60Hz, which is also the standard voltage used in the United States. Countries like Japan have a different grid voltage (100V/50Hz). Smart chargers, which can be connected to any voltage ranging between 90V and 265V and can operate at 50 as well as 60Hz, are ideal for a round-the-world cruise. See page 104 for a few practical tips on 110 to 230V and 50 to 60Hz conversion.

High Power Switch Mode Battery Chargers

Mastervolt’s range of battery chargers comprises more than 20 different models. The IVO Smart series has been developed for the smaller sized service batteries and can be fixed in place or used mobile. Mass battery chargers have been developed especially for larger installations. Both charger types operate according to the so-called high frequency technique, in which advanced microprocessors combine a myriad of functions. All our battery chargers have a similar effect on the batteries they recharge, whether service, starter or bowthruster batteries. As a result, the batteries generate more power, recharge more quickly and have a longer life.

The high frequency technique and why it works so well

Until recently people didn’t take much notice of the type of battery charger they were using or its so-called charge characteristic. You bought a battery charger and that was that. In general you ended up with a half automatic battery charger operating with a resistance characteristic, meaning that your batteries were never fully recharged. Mastervolt introduced the first high frequency or switch mode battery charger in the early 1990s. The main differences between these new models and the more conventional types is that they are light, ultra compact, have an extremely accurate charge characteristic and, as they don’t require humming transformers, produce much less noise. The Mastervolt battery charger shortens the repeat time to factor 10 with the application of microprocessor-guided 3-stage charge technology. The high frequency battery chargers are fitted with precise DC filtering for suppressing interference pulses, which lengthens the battery’s life-span and cuts out all or almost all noise in the electrical system.

Four reasons why a Mastervolt battery charger is your best buy

1. Complete and fully automatic recharging up to 100%

Batteries are vulnerable and, if used incorrectly, will gradually start generating less power. A fully automatic Mastervolt battery charger recharges batteries to 100% with an accurate voltage/current regulation (see below). Automatic temperature compensation and pole sense guarantee a super fast and safe charging process at any temperature.

2. Simultaneous recharging and supplying

Gone are the days when the lights went dim every time the fridge switched on. The charger not only functions as a battery charger but also as a supply unit that automatically makes up the full capacity in the 12/24V circuit when the input voltage is low. The DC outlet of the charger is so ‘clean’ that the appliance can even be used without a battery, as a direct power source. Standard chargers often cause interference in navigation and sound equipment, but Mastervolt’s battery charger generates a minimum ripple on the outlet, leaving the radio and communication equipment free of interference. Mastervolt battery chargers conform to the EMC norms in accordance with CE regulations.

3. Reliable 'filling stations'

Mastervolt battery chargers automatically adjust to the prevailing conditions: in winter the charger will switch itself to the float charge mode, keeping the batteries in top condition. When there is little time available for recharging, the Mastervolt charger quickly switches itself to the BULK stage, using full current; even when there is growing resistance in the battery the charge current remains constantly high. Result: a fully charged battery in the shortest possible time!

4. Longer life for batteries

With a Mastervolt battery charger you won’t need to keep replacing old batteries with new ones. The Mastervolt charge system guarantees a longer life for maintenance-free sealed batteries as well as the open lead type. The battery’s capacity is used much more efficiently as sulphation (i.e. hardening) of the battery plates, which causes capacity loss, is kept to a minimum. Your battery will just keep on going.

Automatic Temperature compensation

Mastervolt’s Smart and Mass battery chargers are standard fitted with automatic temperature compensation to eliminate any danger of explosive oxyhydrogen formation. If the batteries are placed in a hot engine room, for example, and the temperature starts rising around them, the charge voltage is automatically reduced. If the batteries’ temperature remains permanently high, for example in the engine room, the charger automatically switches to a nominal voltage. The temperature sensor, which is supplied as standard with all Mastervolt chargers, has to be attached to the top or side of the main (=hottest) battery. See picture

All Mass battery chargers are delivered as standard with  a temperature sensor with 6 meter cable and telejack plug.

Charging level indicator Model C4-RB basic	In most cases the charger is installed in the engine compartment. We recommend the installation of a small monitoring panel which indicates if the charger is on and shows the different stages of the charging process. This panel is easy to install: we provide additional connection cables to plug&play telejacks.
