  • Overview

    Voltage regulation problems account for more than 90% of the power quality problems seen at most sites. PRAG Voltage Stabilizers provide protection against mains power sags, surges and brownouts.
    PRAG stabilizer has a wide input voltage tolerance, and has been designed to provide the ultimate reliability in hostile environments, where the quality of the mains supply cannot be guaranteed.
    • Wide voltage regulation range
    • Maintenance free roller type carbon brush
    • Individual regulation with unique small dimension
    • High Mean time Between Failure (MTBF)
    • Reliable and quiet servo motors
    • Wheels mounted for easy installation
    • Start up delay to prevent over current in-rush
    • Isolation transformer on request
    • Indoor or outdoor version on request
    HOUSEHOLD: Flats, Houses, Apartments, etc
    BROADCAST: Regulation for broadcast transmitter sites and studios
    COMMERCIAL: High-rise building, elevator control, large A/C chillers, lighting, other  sensitive critical systems.
