StacoAVR
StacoAVR is an electromechanical voltage regulator for installations that need continuous correction without electronic conversion in the power path. Standard models cover 120 to 600 V and ratings up to 2,000 kVA. A microprocessor controls the series-regulation variable transformer, producing full correction in 3 to 30 seconds and maintaining output within ±1% for standard input variations from +10% to −20%.
