SBW / DBW Automatic Voltage Regulator

   SBW/DBW series automatic voltage regulator is designed to stabilize the AC voltage.By using the superposition principle,
compensation method to make the system output from the power grid stably.It can automatically maintain the stability of
voltage output When the fluctuation or load changed.

1. Pure copper coils with excellent electrical conductivity.
2. Good adapbility with wide loads,  compact size and light weight.
3. Protection system: Over load, over voltage, short circuit protection.
4. Higher precision,longer cycle life,more stable voltage.
