Why Similar (Selected Alternates)
- 6EP13315BA10 — same 86% efficiency, IP20, adjustable output, and universal AC input range (85
264 V); differs in lower current (1.3 A vs 2.1 A) and supports DC input (110300 V); belongs to the SITOP PSU100C series. - 6EP13321LB00 — same IP20, adjustable output, and 85% efficiency; operates at a narrower 93
132 / 187264 V input range without universal input support; rated 2.5 A / 60 W in SITOP family. - 6EP13331LB00 — same IP20, adjustable output, and 86% efficiency; rated 5 A / 120 W at a narrower input range (93
132 / 187264 V); the highest current option in this comparison set. - 6EP13322BA20 — SITOP PSU100S series; same 2.5 A, 85% efficiency, IP20, and adjustable output; narrower input band (85
132 / 170264 V); operating temperature 25~70 °C with derating.
Input Flexibility and Mounting Notes for 6EP13311LD00
The 6EP13311LD00 accepts a universal AC input (100240 V nominal, 85264 V operating), making it suitable for installations with unstable mains or multi-region deployments without reconfiguration. DC input is not supported on this model. The unit ships as bulk packaging; DIN rail attachment uses standard snap-fit mounting per IEC 60715. Operating temperature range is 10°C to 70°C with output derating above 50°C; panel builders should confirm thermal margin when mounting multiple units in enclosed cabinets. The IP20 rating confirms this unit is intended for indoor, pollution-degree 2 environments.
