Abstract
An industrial truck is provided with a direct current power supply and at least one electrical user (2), e.g., a lighting device located in a housing, wherein the power supply voltage of the power supply (3) is greater than the nominal voltage of the user (2). To connect the user (2) to the power supply, there is a voltage transformer (4) which is located inside the housing or in the immediate vicinity of the housing. The invention also relates to a voltage transformer which applies a power supply voltage to a user (2) in pulses, so that the power delivered to the user, as an average over time, does not exceed the nominal power of the user (2).
