VGL Equipment

Product information

• Battery charger with the option to preselect capacity for all types of starter battery
• For charging or charge conservation of conventional lead acid, lead calcium/silver batteries, or those of the sealant type (AGM, MF), as well as maintenance-free lead GEL batteries, without disconnecting from the vehicle power supply.
• All functions (battery capacity, nominal voltage, service function, FSV/buffering function) can be clearly viewed and set on the display
  All present charging data (charging current, charging voltage, Ah charged
  so far) are shown on the display
  Based on Active Inverter Technology
  Integral USB port

• Diagnosis and charging mode: Supplies parallel loads during diagnosis. The charger offers maximum safety during this process, with a current of 70 A for Diagnosis mode .
• External power supply without battery, e.g. during battery change, in showrooms or at trade fairs
• Refresh mode: Low-power batteries can be recharged in this mode (desulphating). This process takes place via a microprocessor-controlled IUIoU characteristic.
• Rapid charging thanks to Active Inverter Technology

 Protective features

• Electronic reverse polarity protection
• Thermal overload protection
• Safety cut-out
• Electronically safe

Technology

The innovative concept underlying Active Inverter Technology is based on the combination of a digital control circuit, dU/dt cut-off and an active-rectifi cation inverter. The digital control circuit keeps the charging current and charging voltage constant throughout the charging operation, compensating for any fl uctuations in the mains voltage so that the battery is charged gently and carefully.

The technology behind the dU/dt cut-off stands out for its pro-active responsiveness. The special thing about this is the way in which it takes account of each battery’s age and state of charge and actively fine-tunes the programmed charging characteristic to match. The charging operation is fi nished at the ideal point in time - that is, when the voltage has reached its maximum. This prevents overcharging, reducing water consumption and prolonging battery life by as much as 50 %.
