Quick buying guide for Automatic 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
