Combination of isolator switches and relay in the same housing. The diode distributor works as an isolator. Two additional lines from battery MINUS and D+ of the alternator (or ignition lock PLUS) activate the integrated charging relay. From a control voltage of approx. 10.5 V DC on the "D+" terminal, all inputs and outputs are directly connected to one another and the usual diode voltage loss of 0.5 to 0.7 volts is completely eliminated. With the NAUTIC POWER diodes distributor, almost 100% battery charge is reached in 12 or 24 volt systems. Capacity: 90 A continuous operation, short-term max. 200 A. M8 connecting bolt and two 6.3 mm flat plugs (D+ / MINUS).
