Our Rotavolt variable autotransformers provide a continuous linear regulation of AC voltage, with high efficiency, without distorting waveforms significantly.
The Watford Control Rotavolt provides a precise and effective way of controlling current, light, heat, motor speed or any other type of output that has a voltage factor.
Our Rotavolt autotransformers are the backbone of our EM Voltage Stabilisers, renowned for their unrivalled accuracy and reliability, with tens of thousands of systems in operation around the world.
We offer a range of specifications depending on your needs. Here are some key features to help you choose the best option:
Our range of Servo Controlled and Solid State AC voltage stabilisers, offer a solution to meet the most exacting requirements, from 1kVA right up to 4mVA across single or 3 phase applications...LEARN MORE
Power Conditioners are used to keep voltage spikes and interference at harmless levels, whilst maintaining a stable voltage supply. There will always be some transient noise in any mains...LEARN MORE
