🔄 SITOP Classic vs SITOP Advanced: key differences

The transition from the Classic to the Advanced range provides:

• Higher energy efficiency

• Greater voltage stability in the presence of variable loads

• More advanced protection features

• Better adaptability to modern installations

This transition is often adopted to upgrade existing plants without radically altering their architecture.

🔧 Maintenance and production continuity

Over time, SITOP Advanced power supplies may also be subject to electronic wear.
A proper maintenance approach makes it possible to:

• Prevent unplanned downtime

• Ensure power supply stability

• Extend the service life of automation systems

• Reduce retrofit costs

Advanced maintenance, repair, and remanufacturing activities represent a valid alternative to immediate replacement.
