SBW-F three phase split-adjustable full automatic compensated power voltage regulator

1. Product Features:

SBW –F series three phase split-adjustable full automatic compensated power voltage regulator, this products is three sets of single phase voltage stabilizer composed, and base on SBW series products improvement of voltage stabilizer, applicant to when input three phase voltage unbalance or power network fluctuation and unbalance load current fluctuation, it can keep output three phase voltage in steady state automatically balance, also can keep stable voltage adjustment, output-keep high precision ect virtue, therefore, it has more power and more reliability.

2. Application Scope:

It’s widely used in post and telecommunications, department stores, elevators, hospitals, schools, printing, securities and other occasions where all needs normal voltage to ensure, such as workshop, mines, medium enterprises, some of the important equipment and computer power and support.

3. Technical Parameters:
