Staco AVRs maintain a constant output voltage within ±1% or better, regardless of input voltage variations from +10% to-20% of the nominal input value in standard models. They are also designed and rated to meet standard industry kVA ratings for maximum application compatibility with both new and existing installations. Their performance is guaranteed under all power factor conditions. It doesn't matter if the connected load is capacitive, resistive or inductive.
Staco Automatic Voltage Regulator features:
continuous voltage regulation - no crude step regulation
1% or better output voltage regulation, high efficiency
single phase up to 500kVA, 3-phase up to 1000kVA
optional individual phase control for 3-phase applications
optional isolation transformer for extra protection against noise and transients
