The AC power supply from shore generator or inverter has to be perfectly managed for safety and to ensure your valuable equipment remains undamaged.
Mastervolt gives you the option to switch automatically between available power sources. The Masterswitch will connect the output to the highest priority input if available. Combinating power sources becomes possible for high power consumption situations such as when you want to do the laundry and cook at the same time with a limited shore or generator power supply.
This lightweight Masterswitch with two inputs and one output functions as junction in your 120 & 230 V onboard system. The Masterswitch offers the comfort and safety you need. The simple and effective solution!
