At input voltages below 100 VAC (or below 200 VAC on the high range), output current drops to 80% of the 10 A rating. That means a 10 A load at 90 VAC input delivers only 8 A — plan the branch circuit accordingly. MTBF at 40 °C is 1,292,102 hours — that's over 147 years of continuous operation at that temperature, which keeps the line running without unexpected power-supply failures on the takt cycle. IP20 protection means it's safe for dry indoor panels but not washdown zones. Fastens onto standard DIN rail EN 60715 35x7.5/15 — snaps on without drilling. UL and CSA listed under UL 508 and CSA C22.2 No. 107.1 (File E197259), plus cCSAus to CSA C22.2 No. 60950-1 and UL 60950-1. CE marked, EAC approved. No ATEX, no IECEx, no FM, no UL hazloc — keep it out of hazardous areas.","metaTitle":"Siemens 6EP3334-8SB00-0AY0 Power Supply, 10 A, 120/230 VAC","metaDescription":"Siemens 6EP3334-8SB00-0AY0 power supply, 10 A rated output, dual AC input 85-132/170-264 VAC, UL/CSA/EAC approved, active production, DIN rail mount.
