Booth N3432 Superior Electric’s Power- Stat variable transformers take in utility line voltage and provide continuously adjustable output voltage. They feature rugged construction, high overload capacity, low-resistance, high-efficiency coils and no waveform distortion. A wide range of sizes, drives, enclosures and controls are offered.
The Stabiline WHR series of voltage regulators includes units for use on all AC power systems, up to 660 volts. They hold output voltage within ±1 percent and are available with power ratings from 2 to 1680 kVA. Two input voltage ranges are available and the input ranges are shifted to provide greater low voltage protection. The regulators offer high-overload capacity, low impedance and fast response time with no waveform distortion.
