Frequency Converter

Static Voltage Stabilizer/AVR

BWSVS Series( 10KVA ~ 2000KVA )

For Applications

  • CNC/Medical equipment
  • Electrical Discharge Machining
  • Plastic Injection Machine
  • PCB Drilling Machine
  • Printing Press
  • Embroidery equipment
    Frequency Converter Static Voltage Stabilizer

    Main Features

    • No moving parts,no carbon brushes
    • Maintenance Free
    • Fast response
    • Automatic delay output,
      when the AVR Start Up,
      the voltage will be stabilized
      and then output to protect
      the loads from damage.
    • Inbuilt Automatically Bypass

    Blue Whale BWSVS series Static Voltage Stabilisers are micro-processor based electronic digital regulators and represent the latest in voltage stabiliser design evolution.

    Static Voltage Regulators utilise SCRs (Silicon Controlled Rectifiers) instead of Variable Transformers, to control the voltage on the primary winding to deliver a highly stable output voltage.

    “Compatible with all load types and offering independent phase control, they deliver ultra-fast response times in correcting under / over voltages, sags and surges – making them ideal for highly sensitive / mission critical loads and applications.
    Intended for indoor use only in dry locations, but can be placed in a rain tight enclosure for use in wet or damp locations.”
