| Sag Correction/Regulation |
| Sag Correction |
1 or 2 phase sags - to 30% remaining voltage (-70% sag) corrected to 95% of nominal
3 phase sags - to 60% remaining voltage (-40% sag) corrected to 95% of nominal |
| Output Regulation |
±5% [Note: unit normally operates in bypass mode until voltage drops to a trigger point of 90% of nominal voltage, at which time correction is initiated] |
