Undervoltage protection for on-board and starter battery

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-acid battery types (acid, gel, AGM) and makes. They protect the battery from dangerous deep discharging and the consumers and equipment from undervoltage and overvoltage and, controlled by an external switch, can also be used as a remote-controlled battery main switch.

• EMERGENCY-ON function via switch on the device, can also be operated remotely via external switch
• Automatic reset as soon as the battery voltage returns to the normal range (charging)
• Separate sensor cable and switching thresholds with hysteresis and timer functions for trouble-free operation
• Bistable power relay, very low power consumption, less than 3 mA (according to EN 13976)
• No self-consumption when switching off via external switch, e.g. remote control as battery main switch
• Solid screw terminals for battery and load cable cross-sections up to 10 mm²
• "Motor" version with higher switch-off thresholds maintains the starting capability of emergency vehicles with only one battery circuit in accordance with DIN EN 1789
