Unterspannungsschutz zum Vermeiden von Tiefentladungen

Blei-Säurebatterien nehmen irreparablen Schaden, wenn sie unter die Minimalspannung von typischerweise 10,5 Volt entladen werden.

Aber auch weniger tiefe Entladungen sollten wenn möglich vermieden werden. Hier bietet ein Unterspannungsschutz eine gute Möglichkeit, die Bordbatterien vor Schäden zu schützen, wenn man z.B. aus Versehen den Kühlschrank oder eine Lampe angelassen hat.

Dabei wird ein Relais geöffnet wenn die Batteriespannung unter eine bestimmte Schwelle sinkt und so die Batterie vom Verbraucher getrennt.

Phaesun - Battery monitoring Studer MBW 60

The MBW is an important element in a mobile installation. It increases the lifespan of the batteries and protects them against undervoltage, overvoltage and overload. The detection of the undervoltage can be easily set by a rotary knob. In this way, any lead battery can be protected against too deep discharge. The overvoltage protection prevents damage to consumers with excessive tensions. The MBW can also be used as the main switch. The main switch function cannot be used as long as this switch is not connected. In this case, the MBW only works as a battery protection.: Connection and Disconnection Voltage Programmed by Jumpers, Mosfet Switches, Therefore No Sparks, Alarm Output to Indicate Excessive Voltage Drops,60a, 6-35 VDC battery monitoringArticle No.: 303572Manufacturer: StuderProduct weight: 0.15 kgWeight including packaging: 0.20 kgDimensions: 80 x 60 x 80 mm (L x W x H)
