Siemens 6EP3334-7SC00-3AX0 SITOP PSU6200 Ex 24V/10A Power Supply

The Siemens 6EP3334-7SC00-3AX0 is a SITOP PSU6200 Ex power supply that converts a 120-240 V AC input into a stabilized 24 V DC output rated 10 A, 12 A up to 45 degrees C. Coated circuit boards and ATEX/IECEx Ex ec nC IIC T3 Gc certification qualify it for Zone 2 hazardous areas, and it reaches 92.8% efficiency at 240 W typical supplied power.

Selection Notes

Coated circuit boards plus ATEX/IECEx Ex ec nC IIC T3 Gc certification set this PSU6200 Ex variant apart from the standard PSU6200 24 V/10 A model: it is rated for Zone 2 gas-hazardous areas where the uncoated version is not. At 10 A (12 A up to 45 degrees C) it matches the standard 10 A PSU6200 on output capacity, so the choice between them comes down to whether the installation area is classified; use the non-Ex PSU6200 in unclassified panels to avoid paying for certification headroom that is not needed.

Applications

Sized for 24 V DC control panels installed in Zone 2 hazardous areas — process, oil and gas, or chemical plants — where a 10 A DIN-rail supply must carry ATEX/IECEx certification.
