SBW F Three Phase Split Phase Voltage Stabilizer
The SBW-F series three-phase stepped full-automatic compensation type voltage stabilizer is an optimized and improved stabilizer based on the technology of the SBW series products. It is suitable for power grid conditions where the three-phase input voltage imbalance exceeds 5%. When there is a phase voltage difference caused by three-phase fluctuations or unbalanced load current in the power grid, the three-phase output can automatically balance the voltage while maintaining stable voltage regulation.
