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 doesnt 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.FeaturesAutomatic switchingOne outlet to AC power groupTwo AC inputs, for example grid power and generatorPower transfer up to 25 kW, input/output from 20 to 125 AThe Masterswitch Fuses version includes circuit breakers.General SpecificationsNominal input voltage: 120 V (50/60 Hz)Input voltage range: 100-125 VNumber of inputs: 2Number of outputs: 1Dimensions (H x W x D): 200 mm (7.9″) x 110 mm (4.3″) x 115 mm (4.5″)Weight: 1.2 kgTechnical SpecificationsConnection for remote control: NoLED indication on enclosure: NoNominal input current generator: 25 ANominal input current grid: 25 AGenerator input switch: NoTime delay generator input: 0-10 sec.
