APPLICATION SBW-F series avr automatic voltage regulator three-phase sub-regulation full automatic compensation power voltage regulator is a new voltage regulator improved based at SBW series products, which is suitable for unbalanced three-phase input voltage grid. When the load current changes or fluctuations in power grids, three-phase output automatically balance, and keep the merits of a steady voltage regulator USE SITUATION 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. SPECIFICATIONS Input voltage Single phases: 175V-265V Three phases four-line 175V-265V(phases voltage)300V-456V(Linevoltage) 260V-500V, 270V-490V Output voltage Single phases: 220V Three phases: 380V Output deviance: 1-5%Adjustabl Frequency: 50Hz/60Hz Efficiency: ≥95% (Power>50kVA) Response time: ≤1.5S Ambient temperature: -10ºC--+40ºC Insulation resistance: ≥2MΩ Electrical intensity: Without breakdown and flashover phenomena at power frequency Sine voltage: 2000V for 1 min Overload: Double rated current, one min. Waveform distortion: Non-lack fidelity wareform Protect: Overvoltage, overcurrent, feed phases
