Quick buying guide for Static Voltage Stabilizer

Here are the key factors to select suitable voltage stabilizer for you

  • Number of phases
    • Single phase load, choose single phase voltage stabilizer
    • Three phase load, choose three phase voltage stabilizer
  • Rated voltage and frequency
    • Norminal voltage 380V, 400V, 415V, 440V, 480V etc.
    • Frequency 50Hz or 60Hz
    • Neutral line availability(3 phase 3 wire or 3 phase 4 wire)
  • Input voltage range
    • Symmetrical: ±15%, ±20%, ±25%, ±30% (Other on request)
    • Asymmetrical: +15%/-25%, +15%/-30%, +15%/-40% (Other on request)
  • Power
    • kVA(single phase) = load voltage * load current
    • kVA(three phase) = √3 * phase to phase load voltage * load current
    • Consider at least 30% extra safty margin for possible future expansions
  • Installation
    • IP protection
    • Indoor or outdoor
