Regavolt

The REGAVOLT Autotransformer.

It is a highly efficient device for low-loss AC voltage control and is widely used for regulating parameters such as current, power, temperature, light intensity, and motor speed.

Core Features & Operation

• Continuously Adjustable Output: The output voltage is smoothly varied via a special brushgear that traverses a prepared track on the transformer winding, allowing for on-load voltage adjustments.
• Compact & Efficient: REGAVOLT transformers are much smaller than resistive controllers of the same power rating and do not waste energy as heat, unlike resistive devices.
• Waveform & Power Factor: Unlike solid-state controllers, REGAVOLT transformers maintain waveform purity and do not affect power factor.
• DC Compatibility: While they cannot operate directly on DC, REGAVOLT transformers can provide variable DC voltage and current when used with rectifiers.

Key Advantages

• Good Regulation: Output voltage remains substantially independent of the load.
• Smooth Control: Voltage is continuously adjustable from near zero up to (and sometimes above) the supply voltage.
• High Efficiency: Modern design and advanced materials ensure very low losses under all load conditions.
• Small Size: Much more compact than equivalent resistive controllers.
• Linear Output: Output voltage varies linearly with the angle of the control knob.
• Moderate Temperature Rise: No derating is required for ambient temperatures up to 45°C.
