Mastervolt Masterswitch - 3kW (120V)

The Mastervolt Masterswitch is the heart of the AC installation. It is designed to take over manual switching between two different power sources, automatically transferring the available AC power source to the output. Automatic switching between the power sources doesn’t only offer you more comfort, it also improves the safety on board. The switching between the power sources which is done by means of a relay, assures that no short-circuiting will occur. The Masterswitch has two inputs and one output.

• Automatic switching
• One outlet to AC power group
• Two AC inputs, for example grid power and generator
• Power transfer up to 25 kW, input/output from 20 to 125 A
