Isolation relay WT662 120A 12V

Das Relais wird zwischen zwei Batterien verbaut. Sobald die Zündung am Fahrzeug an ist, schaltet dieses die Zusatzbatterie zur Stromversorgung zu. Dadurch ist es auch für längere Standzeiten des Fahrzeuges ideal, denn durch das Relais kann die Hauptbatterie nicht entladen werden. Im Winter bringt dies zusätzlich Vorteile, da man mit zwei Batterien mehr Kaltstartstromstärke zur Verfügung hat.
Endlich Schluß mit dem Thema "Mein Fahrzeug springt nicht an!".

Isolation relay WT662
12 V / 120 A
 

Function

For the use of a secondary battery in a vehicle it is recommended to install an isolation relay. The installation of this relay ensures that the connection between the batteries is cut-off as long as the engine is turned off. Only if the engine is ignited, the secondary battery is connected. Especially if the vehicle is not used for a longer period, this system avoids mutual discharging of the batteries. As soon as the engine is running, both batteries get charged by the alternator.

Applications

  •     CarHifi
  •     Boats
  •     Caravan and Camping
  •     Solar systems
  •     etc.
