Dometic Büttner MT NU 2300 Mains Priority Switch for Inverters, 2300 VA
Automatic Switching Between Inverter and Shore Power
The Dometic Büttner MT NU 2300 mains priority switch automatically switches the 230 V power supply between a sine wave inverter and an external shore power supply. It is particularly suitable for motorhomes and caravans with an inverter that does not have an integrated mains priority or transfer switch.
As soon as an external 230 V mains supply is available, it automatically takes priority over the voltage supplied by the inverter. The connected 230 V appliances and onboard sockets are then supplied by the external mains connection. When external mains power is no longer available, the power supply switches back to the inverter.
This eliminates the need to switch manually between inverter and shore power operation and prevents the onboard battery from being unnecessarily used to provide 230 V power via the inverter when shore power is available.
Mains Priority Switch for Sine Wave Inverters Without an Integrated Transfer Switch
The Dometic Büttner MT NU 2300 is designed as an addition to sine wave inverters without their own integrated mains priority switch. Its use is not limited to Dometic or Büttner inverters.
The mains priority switch features one input for the external 230 V mains or shore power supply, one input for the AC voltage supplied by the inverter and one output for supplying the connected 230 V appliances.
Up to 2300 VA Output Power and 10 A
The transfer switch is designed for a maximum load of 2300 VA and 10 A, making it suitable for appropriately rated 230 V electrical systems in recreational vehicles.
The automatic priority switching ensures that the external mains supply is used whenever both mains and inverter voltage are available. Only when the external mains supply is no longer available is power supplied via the inverter connected to the onboard battery.
For Motorhomes and Caravans
The automatic transfer switch allows an existing inverter installation to be conveniently integrated into the 230 V electrical system of a motorhome or caravan. The connected sockets can be used both when an external mains supply is available and when operating from the inverter.
The Dometic Büttner MT NU 2300 automatically switches between the two available power sources. Installation and cable sizing must comply with the specifications in the installation manual.
