A complete blackout isn’t the only threat to your plant floor. In fact, deep voltage sags, swells, and momentary power dips are far more common and can be just as destructive to your operational uptime. A split-second voltage sag is all it takes to trip a heavy-duty variable frequency drive, reset a critical PLC, or ruin a continuous production batch.
When facility managers look to protect their systems from grid instability, they traditionally default to massive Uninterruptible Power Supply (UPS) systems.
But as highlighted in ABB’s latest overview of the PCS100 AVC-40 (Active Voltage Conditioner), there is a much smarter, leaner way to secure your plant: battery-free protection.
The Battery-Free Advantage
Traditional UPS systems come with a massive hidden cost: the batteries. Battery banks require large, climate-controlled footprints, rigorous routine maintenance, and expensive full-system replacements every few years.
The ABB PCS100 AVC-40 takes a completely different engineering approach. It provides continuous voltage regulation and deep sag mitigation without utilizing a single battery.
Instead of relying on stored energy, the AVC-40 uses an advanced power electronic converter to instantly draw additional current from the existing utility supply. It uses this current to inject the exact missing voltage required to maintain a perfect sine wave for your equipment. If the grid voltage drops, the AVC-40 corrects it in less than two milliseconds—ensuring your automation systems never even notice the dip.

What SEMI F47 Compliance Actually Means
The video specifically notes that the PCS100 AVC-40 is SEMI F47 compliant. For industrial engineers, this is a critical specification.
SEMI F47 is an incredibly strict voltage sag immunity standard originally developed for the semiconductor manufacturing industry—an environment where a microsecond power fluctuation can instantly scrap millions of dollars worth of silicon wafers.
Achieving SEMI F47 compliance means the PCS100 AVC-40 has been independently proven to maintain operational continuity under severe, defined voltage sag conditions. If it can protect highly sensitive microchip fabrication plants, it can easily secure your factory’s pumps, extruders, and packaging lines.
