In modern electrical installations in vehicles, personal safety is important. This safety is achieved with the US-TSFI transfer switch with 4-wire 30mA fault current protection. The various UltraSine inverters from 150W to 1600W are available for the 230V power supply. In addition, a land connection is increasingly being used via the external supply in order to feed all 230V consumers in the vehicle when the mains supply is present and, at the same time, to charge the battery (s) when the charger is installed. The US TSFI automatically takes over all the switching functions and guarantees the best possible protection with the 4-wire FI switch. The IBS Transfer switch offers the best possible protection against unwanted electric shock even in the case of insufficient fault current protection of the shore connection.
