Functions

• Low-loss serial controller
• PWM-controlled constant-voltage charging
• Battery charging with automatic charging
  mode selection (float, boost, equal)
• Recognizes and carries out a maintenance charge
  (boost charge every 30 days if idle)
• Automatically adjusts to the voltage level 12 V/24 V
• Current-dependent load deactivation
• Automatic load reactivation
• Temperature compensation
• Grounding on the plus side
• Integrated self test (start voltage 17.0 V)
• Made in Germany (development and production)    

Display

• 4 separate LEDs to display the battery charge status
• LEDs (red/green) to display the function status

Electronic protection functions

• Battery-overload protection (HVD)
• Deep-discharge protection (LVD)
• Automatic electronic fuse
• Reverse-polarity protection at module input, of the load and the battery connection
• Reverse-polarity protection of the module
• Short-circuit protection of the load and the module
• Good electromagnetic compatibility
• Idling protection in case no battery is connected
• Prevention of back current into the module
• Integrated temperature compensation of the end-ofcharge voltage (0 °C to +50 °C, factor -4mV/K/cell)
