Control transformer Isolation transformer UL/CSA recognized 500V primary, 230V secondary Screw/flat terminal connections Meets EN 61558 standards

Product description

The Siemens 4AM4842-5FT10-0FA0 is a 1-phase SITAS control and isolation transformer designed for reliable power conversion in industrial applications. It features a primary voltage of 500V with a +/-5% adjustment range and a secondary voltage of 230V, delivering a power rating of 0.5 kVA (or 2 kVA for S6 duty). The transformer operates efficiently across a frequency range of 50 to 60 Hz and has a temperature rise of 40°C with an insulation class of B.

This transformer is built to meet stringent safety standards, including EN 61558-2-1, -2-2, and -2-4, and is UL/CSA-recognized. It comes with an IP00 protection rating, indicating it requires enclosure within a control cabinet. Connections are made via screw or flat-type terminals, and mounting is secured by screws. Its vector group is II0 with no shielding winding.
