The VOTRONIC Battery Protector 40 and Battery Protector 100 devices are connected between the supply battery and the consumer and are suitable for all lead battery types (acid, gel, AGM) and brands. They protect the battery from dangerous total discharge and consumers and equipment from under and overvoltage and, controlled by an external switch, can also be used as a remote-controlled main battery switch.

Operation as Battery Protector:

  • Optical display of the operating status by two LEDs
  • Acoustic alarm can be activated (sounds when the pre-warning threshold is reached or when the device is switched off)
  • Output for external alarm display (max. 0.3 A, short-circuit proof)
  • Suitable for all common lead battery types with 12 V or 24 V nominal voltage (acid, gel, AGM,...)
  • Suitable for lithium batteries (LiFePO4)
  • Can also be used as a powerful battery main switch with protective function
  • Various switching thresholds can be configured
  • The shutdown can be canceled manually at any time using the EMERGENCY ON function

Operation as a switch unit:

  • Can be used as a battery main switch
  • Electronic delay prevents too rapid a reaction, eg in the event of voltage dips caused by switching on heavy consumers.
  • Optical display of the operating status by two LEDs
  • Alternatively, it can be used as a remote-controlled power relay (“Switch Unit”), eg on the LCD Battery Computer S.
