FAQ

Question?

Can the output voltage of the 6EP1 333-2AA01 be adjusted?

Answer:

Yes, the output voltage is adjustable via a potentiometer, typically in a range from 22.8V to 28V DC, allowing for compensation of voltage drops in long cables.

Question?

What is the difference between this SITOP smart (PSU100S) and the SITOP modular series?

Answer:

The SITOP smart series is a line of compact, standard power supplies for basic industrial requirements. The SITOP modular series offers higher functionality, such as enhanced diagnostics, signaling contacts, and the ability to be combined with buffer, redundancy, and selectivity modules for more complex and critical applications.

Question?

Is the 6EP1 333-2AA01 capable of parallel operation to increase power output?

Answer:

Yes, these units can be connected in parallel to increase the total current output. When doing so, it is crucial to ensure both power supplies are set to the exact same output voltage to enable proper load sharing.
