Why These Parts Are Catalog-Similar
6EP33337SC000AX0 shares the same Siemens series (6EP33337) and matches the primary part's output rating (5 A, 120 W), AC input band, DC input window, and efficiency. It is listed as a SITOP PSU6200 variant and shares the adjustable-output and IP20 feature set. The distinction lies in agency coverage: the primary lists cCSAus and cULus, while this alternate lists only CE, CSA, and UL.
6EP33337LB000AX0 also shares the Siemens 6EP33337 series prefix, the same universal AC input range, DC input limits, adjustable output, and IP20 rating. Rated current is 3.7 A (89 W), and efficiency is 89.3 %.
6EP34347SB003AX0 shares the Siemens DIN rail supply family, adjustable output, IP20, and agency certifications. However, the AC input band is shifted to three-phase 400–500 VAC (323–576 VAC extended range), the DC input window is higher (450–600 VDC), and output doubles to 10 A / 240 W with higher efficiency of 95.4 %.
