Multi chemistry platform charger

ML334-SerienThe 4-channel ML334 charger is designed for demanding Ground Mobile use. The charger is used by several national Defence Forces in extremely severe military applications during all type of weather conditions. Due to the wide AC supply range the charger can be used worldwide. The charger can easily be used in vehicles by using a vehicle tray from Natek. The charger is very easy to operate; it has no switches nor are other adjustments necessary for the charging process. The charging process is fully automatic. Connected batteries are charged independently of each other. The battery adapter fitted on top of the charger contains data about battery chemistry, charging voltage, charging current, timer etc. The charger adjusts the charging parameters to fit exactly the battery types the battery adapter is designed for. By replacing the battery adapter, other types of batteries can be charged. The adapter can be configured for connecting the charging outputs in parallel, making it possible to charge batteries with increased charge current.
