SBW Three-Phase Industrial Automatic Voltage Stabilizer | 30-1000kVA

Heavy-duty servo regulator, output 380V ±2%, for factory & plant mains

HK$1800.00

Overview

The SBW is a heavy-duty three-phase servo voltage stabilizer for industrial mains, independently regulating each phase to hold a precise 380 V output for production lines, CNC machines and plant equipment exposed to severe grid fluctuation.

Key Features

  • Independent per-phase regulation, balanced 3-phase output

  • High efficiency ≥98%, step response within 0.5 s

  • Over/under-voltage, overload, phase-loss, short-circuit and bypass protection

  • Adjustable output band (±1-5%), digital controller optional

  • Large capacity range up to 1000 kVA, cabinet floor mounting
