Utility feeds are never perfectly reliable. Voltage sags, swells, and full outages happen — from lightning, grid faults, switching transients. The traditional fix, mechanical contactors, takes 200+ milliseconds to swap feeders. That’s an eternity for IT power supplies, motor drives, PLCs, and life-safety equipment.

What the research says:

• 52 % of data centre outages are caused by on-site power issues; 54 % cost more than $1 M. (Uptime Institute, 2023)
• 37 % YoY rise in petrochemical incidents — power loss disables ESD, gas detection, and pressure relief systems. (AOC Corp, 2025)
• Food & beverage manufacturers lose $4 K–$30 K per hour of stoppage; 28 % of unplanned stops are electrical. (Oxmaint, Gitnux 2026)
• In healthcare, hospital power failure is a documented patient-safety hazard — with 233 deaths recorded from power failure in Venezuelan hospitals between 2019–2021. (APSF; etkho)
• 42 % of US manufacturing unplanned downtime traces back to equipment failure — often power-induced. (Gitnux, 2026)

The ASHE SPX-21D Static Power Switching Unit, distributed by Sparktech Automation, transfers between two AC feeders in under 10 milliseconds — less than half a 50 Hz cycle.
