1 Device Description

1.1 Area of application

The battery-charger and trickle-charger EL11 serves for the charging and trickle-charging of discharged
partly-discharged and deep-discharged batteries from closed (open) or sealed Lead-Acid-batteries with
24V nominal voltage and nominal capacities between 45Ah and 500Ah. Lead-Acid-batteries with liquid
electrolyte as well as sealed batteries in GEL- or AGM-technology can be charged. Alternatively the 5A-
area or the 10A-area can be used. The device additionally can be used as constant voltage power
supply with up to 10A. Based on the protection level (IP65) the charger can be used in closed shops as
well as under shelters or in open air.

NOTICE
The implemented version works - differently from the German VG requirements - with a temperature
compensation performing the voltage correction parameters advised by the battery producers. This
means even under extreme climatically circumstances optimum charging results are performed. Battery
damages are reliably avoided. The following values of charging voltages are referred to an ambient
temperature of 20°C.
