WHR Series STABILINE® Automatic Voltage Regulators maintain constant voltage to your equipment, even when the input voltage and system load vary widely.

    The post Superior Electric WHR – STABILINE Automatic Voltage Regulator appeared first on Electro-Meters.

    ]]>     Lightning strikes, line disturbances and uneven loads cause disabling transients, spikes, sags and surges. Left unregulated, these conditions will degrade- even destroy sensitive broadcast electronics in receiving stations, studios, mobile production vehicles and transmitter sites. Avoid catastrophic equipment failure, software damage, reduced power tube life and poor signal quality with WHR Voltage Regulators.

    STABILINE Automatic Voltage Regulators are designed for use on all AC power systems, up to 660 volts. WHR Series STABILINE Voltage Regulators use standardized control modules, power modules, enclosures, and other options. Control module options include single phase and individual phase control, power circuit options include narrow or wide correction ranges, and enclosure options include floor and rack mount housings. All STABILINE Voltage Regulators are designed and built specifically for regulator use and are currently in operating internationally.

    All WHR voltage regulator models utilize our core product technology of special POWERSTAT® Variable Transformers, also uniquely designed for regulator use. POWERSTAT® offers a Limited Range coil design allows for substantially higher current and power ratings without increasing unit size or weight. This is accomplished by utilizing a “limited” portion of the coil windings to provide regulation. The design allows for direct control of the output voltage without the need of secondary devices such as buck/boost transformers and tap switching semiconductors.

    STABILINE WHR’s, rated from 2 kVA to 1680 kVA, offer exceptional protection to help broadcast facilities maintain output voltage to ±1% with 99% efficiency. STABILINE regulators automatically feed voltage sensitive equipment a constant voltage level with no waveform distortion, and they have a high overload capacity. Innovative modular construction is key to our ability to offer such a wide variety of regulators with excellent quality, fast delivery and competitive pricing
