Charger converter

General:
• Multi-functional
The name of Multi comes from the many functions it can offer. It is a powerful sine wave converter, a sophisticated battery charger that features adaptive charging technology and a high-speed AC power transfer switch in one compact package.
Apart from these primary functions, however, the Multi has several advanced features that offer a range of new applications as shown below. • Uninterrupted AC power
In the event of a mains power failure, or if shore power or generator power has been disconnected, the Multi's inverter is activated automatically and it takes over from the connected loads.
This is so fast (less than 20 milliseconds)  computers and other electronic equipment will continue to operate without interruption.
• PowerControl - Lateral wharf or limited generator power processing capability
A maximum shore or generator current can be installed with a Multi Control Panel. The Multi will then take into account other AC loads and it will use all that is extra for charging, preventing the generator or shore power from being overloaded.
• Programmable relay
The Multi is equipped with a programmable relay, which is configured by default as an alarm relay. This relay can be programmed for all types of applications, for example as a starter relay for a generator.
Battery charger:
• Adaptive load characteristics in 4 steps: bulk - absorption - float - standby
The adaptive microprocessor controlled battery management system can be set for various types of batteries. The "adaptive" function automatically adapts the charging process to the use of the battery.
  • The right dose of load: variable absorption time
In the case of a light battery discharge, the absorption is kept reduced in order to prevent overcharging and excessive gas formation. After a large unload, the absorption time is automatically raised to fully charge the  battery.
  • Prevention of gassing damage: BatterySafe mode
If, in order to quickly recharge a battery, a high load power is associated with a high absorption voltage, the deterioration due to excessive gassing will be avoided by automatically limiting the progression of the voltage, as soon as the gassing voltage has been reached. .
  • Less maintenance and aging if the battery is not used: standby mode
Standby mode is triggered when the battery has not been used for 24 hours. In standby mode, the float voltage is reduced to 2.2V / cell (13.2V for a 12V battery) to minimize gassing and corrosion of positive plates. Once a week, the  Voltage is raised at the absorption level to "equalize" the battery. This process prevents stratification of the electrolyte and sulfation, major causes of premature aging of batteries.
  • Two DC outputs for charging two batteries
The main terminal CC can provide the entire output current. The second output, intended for charging a starter battery, is limited to 1A and its output voltage is slightly lower.
  • Increased battery life: temperature compensation
The temperature sensor, which is supplied with the product, serves to reduce the charging voltage as the battery temperature increases. This is especially important for maintenance-free batteries that may dry out due to overload.
