Siemens 4AM4842-8DD40-0FB0 SITAS Isolation Transformer - 0.5kVA
Siemens SITAS 1-phase isolation transformer 4AM4842-8DD40-0FB0.
The Siemens 4AM4842-8DD40-0FB0 is a single-phase SITAS isolation transformer, part of the same series as the 4AM4842-8DD40-0FA0, likely differing in a minor specification or marking not detailed in the basic description. It is rated for 0.5 kVA (S6 rating of 2 kVA) with a wide primary voltage range from 550V down to 208V, providing dual 115V secondary outputs. The secondary current is rated at 2x2.17A. Operating at 50-60 Hz, it features a vector group of II0/0 and shielding winding, with a 40°C temperature rise and insulation class B, and IP00 protection.
This transformer is designed for industrial control applications demanding electrical isolation and stable dual 115V power. It is built to the same high standards as other SITAS transformers, complying with EN 61558-2-1, -2-2, and -2-4, and is UL/CSA recognized.
