Charging Converter VCC IUoU

Fully automatic battery charging converter for special vehicles, motorhomes and boats.

The charging converters (boosters) have been developed according to the latest specifications for charging supply batteries (RV batteries) with lead-acid, lead-gel or lead-AGM technology while travelling.

In contrast to conventional cut-off relays, the charging voltage is increased depending on the charging specification in the case of long supply cables or insufficient cable cross-sections. This compensates for losses.

The charging converter thus provides the well-known high quality of battery charging of the VOTRONIC chargers even while driving. The intelligent microprocessor charging control with "IU1oU2" charging characteristics and dynamic charging time calculation automatically ensures fast and gentle full charging and subsequent 100 % charge retention of the connected batteries from any state of charge. At the same time, it always enables the simultaneous supply of 24 V consumers connected in parallel. Overcharging or excessive gassing of the batteries is prevented even during extremely long driving times.

The charging converters in the "IUoU" series are characterised by their compact design, low weight (high-frequency switch-mode technology), powerfully dimensioned power components and thus full charging power even with long charging cables and strong voltage fluctuations at the starter battery (e.g. in vehicles according to Euro 6 standard).

• Gel, AGM, acid, LiFePO4* (except 24 V)
• Galvanic insulation
• Lead temperature compensation
• Automatic activation D+, ignition
• Sensor cable connections for input/output
• Remote control connections, display
• Temperature sensor 825 included in delivery
• The charging voltage is free of peaks and regulated in such a way that overcharging of the batteries is ruled out.
• Fully automatic operation via switching input (ignition, engine running) and voltage control
• The automatic, adjustable power control enables the starter battery to be charged by the alternator as a priority in the event of an overloaded vehicle network, thus ensuring that the vehicle can be started immediately.
• No discharge (current 0.000 A) of the batteries during standby or when the charging converter is switched off.
• Parallel and buffer operation: The battery continues to be charged or is kept fully charged when the vehicle is being used at the same time. The charging converter automatically calculates and monitors the adjustment of the charging times.
• Monitoring-free charging: protection against overload, overheating, overvoltage, short circuit, reverse polarity at the output, malfunction and battery back-discharge through electronic cut-off up to complete disconnection of the charging converter and battery through built-in safety switches.
• Galvanic insulation between input and output: absolute separation of the battery circuits even in the event of a fault and clean earth conditions even with long supply cables. Particularly important when charging 24 V systems from 12 V system voltage.
• Charging cable compensation: voltage losses on the charging cables are automatically compensated for.
• Charging aid for deeply discharged batteries: gentle charging of the battery from 0 V to 16 V, then powerful support for the battery if consumers are still switched on.
• Built-in on-board filter: problem-free parallel operation with solar systems, wind and petrol generators, mains chargers, etc. on one battery.
• Temperature compensation: automatic adjustment of the charging voltage to the battery temperature using an external temperature sensor (322/898). Improves the full charge of the weaker battery in cold weather and prevents unnecessary battery gassing in summer temperatures. Highly recommended if the battery/batteries is/are exposed to strong temperature fluctuations, e.g. in the engine compartment or storage compartment.
