Above +60°C, derate by 3% per Kelvin up to +70°C — so at +65°C you're looking at roughly 10.2 A available. It accepts 85-275 VDC input, making it usable on DC bus systems or battery-backed installations without an AC feed. The 12 A headline number is the short-term peak at moderate ambient — the real continuous rating is 10 A unless you keep the cabinet below 45°C. That derating curve matters for an enclosed panel with other heat sources. The 85-275 VDC input range means this unit can sit on a 110 VDC or 220 VDC plant battery bank without an intermediate converter. Galvanic isolation is SELV per EN 60950-1, so the output is safe to touch and suitable for feeding control circuits directly. Mounting is snap-on DIN rail — no screws, no bracket. The input side uses PushIn terminals accepting 0.5-4 mm² single-core or finely stranded wire. Output side uses PushIn for 0.5-2.5 mm². That means no tool needed for termination, just strip and push. The recommended upstream protection is a circuit breaker 4 A char C / 6 A char B up to 10 A char C, or a 3RV2011-1EA10 set at 4 A.","metaTitle":"Siemens 6EP3334-7SB00-3AX0 Power Supply, 12 A, 85-275 VDC In","metaDescription":"Siemens SITOP PSU6200 power supply, 12 A output, 85-275 VDC input, UL/CSA listed, IP20, current production.
