Xishun TNS/SBW Series Three-Phase High Power Compensated Regulators Voltage Regulator

✅ Three sets of independent pure copper voltage-regulating windings, with separate adjustment for each phase, to address three-phase voltage imbalance in the power grid
✅ Servo motor-driven carbon brush voltage regulation mechanism ensures smooth voltage adjustment, preventing surge damage to downstream precision equipment
✅ Compact, vertical sheet-metal enclosure equipped with casters at the base, allowing for flexible and convenient relocation and on-site setup
✅ Control panel features independent three-phase voltage meters for real-time, intuitive monitoring of the power supply status for each phase
✅ Comprehensive multi-level electrical protection system that rapidly safeguards core components—such as lasers and servo motors—in the event of power grid abnormalities
