Siemens 4AM4842-5AT10-0FA0 SITAS Control Transformer - 0.5kVA
Siemens SITAS 1-phase control transformer 4AM4842-5AT10-0FA0.
The Siemens 4AM4842-5AT10-0FA0 is a single-phase SITAS control transformer rated at 0.5 kVA (S6 rating of 2 kVA). It features a primary voltage of 400V (with +/-5% tolerance) and a secondary voltage of 230V, delivering a secondary current of 2.17A. This transformer operates efficiently at 50-60 Hz and has a vector group of II0/0 with shielding winding. It is designed for a 40°C temperature rise and insulation class B, with an IP00 enclosure rating. Connection is facilitated by screw/flat-type terminals, and it is mounted using screws.
This transformer is well-suited for control applications where a 230V supply is needed from a 400V source, common in European industrial settings and specific machinery. It complies with EN 61558-2-1, -2-2, and -2-4 standards, making it an isolation transformer and recognized by UL/CSA.
