Votronic Battery Protector 300

Undervoltage protection for on-board and starting battery

The VOTRONIC Battery Protector 40 and Battery Protector 100 are connected between the supply battery and the consumer and are suitable for all lead-acid battery types (acid, gel, AGM) and makes. They protect the battery against dangerous deep discharge as well as the consumers and equipment against undervoltage and overvoltage and, controlled by an external switch, can also serve as a remote-controlled battery master switch.

Operation as Battery Protector:

• Visual indication of operating status by means of two LEDs
• Acoustic alarm can be activated (sounds when the prewarning threshold is reached or when the unit is switched off)
• Output for external alarm display (max. 0.3 A, short-circuit proof)
• Suitable for all common lead-acid 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 EMERGENCY ON function can be used to manually cancel the switch-off at any time

Operation as a switch unit:

• Can be used as a main battery switch
• Electronic delay prevents too fast a reaction, e.g. in the event of voltage dips caused by switching on heavy consumers.
• Optical indication of the operating status by two LEDs
• Alternatively, it can be used as a remote-controlled power relay ("switch unit"), e.g. on the LCD battery computer S.
