Three-phase voltage stabilizer 3 ESTAB 2500

automatic

Three phases automatic AC. voltage stabilizers very efficient also on large instability voltage. There are two families 3ESTAB and BST models Small and middle size 3ESTAB models are full soM state voltage stabilizers; Ihey are operating an independent phase control so that each phase is controlled and system gives perfectly voltage stability also with unbalanced load Built-up from three single monophase stabilizers connected together Htth wtn ng box and assembled each up to the other Optional rack cabinet Big size BST models are operating on phases average with electronic control and electromechanical regulator rugged and very reliable they include storm lightning protection
