Votronic 3075 Battery Protector 40 Motor 40A 12V Battery Monitor

The VOTRONIC Battery Protector 40 Motor is connected between the supply battery and the consumer and is suitable for all types (acid, gel, AGM) and brands of lead-acid batteries. It protects the battery from dangerous deep discharge and protects consumers and equipment from under- and overvoltage. Controlled by an external switch, it can also serve as a remote-controlled battery main switch.

Compared to the "normal" Battery Protector 40, the Motor version switches to undervoltage at 11.8V.

The device automatically resets to normal operation as soon as the voltage has risen to 12.5 V, for example, due to battery recovery or a short charging period. The shutdown can also be manually overridden using the "EMERGENCY ON" function. The Battery Protector 40 can be remotely controlled via the "Sensor +" terminal with a simple switch (1-pole ON/OFF). This turns it into a powerful main battery switch. The EMERGENCY ON function can also be remotely controlled

important product features

• Switching current 40 A, can be overloaded to 60 A for a short time, externally visible switching status indicator
• EMERGENCY ON function via switch on the device, can also be remotely controlled 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 power consumption when switched 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 starting capability in emergency vehicles with only one battery circuit in accordance with DIN EN 1789
