The manual for my #furman #powerconditioner (s) says: "The EXTREME VOLTAGE (EVS) LED ... is normally off,
but illuminates red when ... the PS-8RE III encounters a line voltage above the EVS threshold (275 VAC) ... the SMP will disconnect the power from the rear panel outlets and the EVS LED will activate."
How is this possible when the #usp is supposed to do "Automatic Voltage Regulation"? 🤔
