Siemens 6EP3336-7SC00-3AX0 SITOP PSU6200 Ex 24V/20A Power Supply

The Siemens 6EP3336-7SC00-3AX0 is a SITOP PSU6200 Ex power supply that converts a 120-240 V AC input into a stabilized 24 V DC output rated 20 A, 24 A up to 45 degrees C. Coated circuit boards and ATEX/IECEx Ex ec nC IIC T4 Gc certification qualify it for Zone 2 hazardous areas, and it reaches 95.5% efficiency at 480 W typical supplied power.

Selection Notes

This is the highest-current Ex-rated PSU6200 in the 24 V line, doubling the 6EP3334 Ex variant's 10 A rating to 20 A (24 A up to 45 degrees C) in a wider 70 mm enclosure while keeping the same ATEX/IECEx Zone 2 certification. Use it to consolidate a Zone 2 panel's 24 V loads onto one supply instead of paralleling two smaller Ex units, and drop to the 10 A Ex model when the panel load stays under roughly 12 A to save enclosure width.

Applications

Sized for larger 24 V DC control panels installed in Zone 2 hazardous areas that need more than 10-12 A of continuous DC load on a single certified supply.
