Product Highlights


POWERSTAT® Variable Transformer

Rugged, and designed for heavy-duty use, POWERSTAT® Variable Transformers provide excellent power regulation with negligible variation in output voltage from no-load to full-load current. They provide a simple, rugged method of controlling electrical voltage, current and power. They take in utility line voltage and provide continuously adjustable output voltage. Available in both manual and motor-driven options, they offer high current ratings, long life, superior overload capacity and exception resistance to contaminants such as fungus and salt spray.

STABILINE® Automatic Voltage Regulators

STABILINE® Automatic Voltage Regulators for use on all AC power systems up to 660 volts. The regulator maintains constant voltage to your equipment, even when the input voltage and system load vary widely. The Limited Range coil design allows for substantially higher current and power ratings without increasing unit size or weight.
