This transformer has a bridge rectifier with downstream filtering for 24 VDC / 1 A. The design of the housing is more like a contactor than a classic transformer and thus enhances the control cabinet. The output voltage is not regulated and depends on both the input voltage and the connected load. The input side is connected to a 1-phase network or between 2 phases of a 3-phase network with a nominal voltage of 230 VAC or 400 VAC. In addition, connections are available for adjusting +/-15 VAC. The mains frequency range is 50/60 Hz.
