Frequency Converter

Automatic Servo Voltage Stabilizer/AVR

BWSVC Series ( 1KVA ~ 100KVA )

For Applications

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

Main Features

  • Wide range of permissible input
    voltage windows (±20% to ±40%)
  • Automatic delay output, when the
    AVR Start Up,it will not output
    untill the voltage has been
    stabilized to protect the loads
    from damage.

Blue Whale BWSVC series Servo Voltage Stabilizer is designed to regulate voltage automatically – that is to take a fluctuating voltage level and turn it into a constant voltage level.

“It will also keep the output voltage stable during peak loads, thus helping CNC/PLC/Medical/
Laser/Printing equipment and other voltage-sensitive equipment to operate properly.”

“Inbuilt protection also ensures that the load is continuously protected against harmful mains born high energy surges, spikes and transients.
Intended for indoor use only in dry locations, but can be placed in a rain tight enclosure for use in wet or damp locations.”
