Voltage Stabilisers

The Claude Lyons electromechanical and electronic voltage stabilisers represent cutting-edge solutions for managing power fluctuations and ensuring stable electricity supply for your equipment. Each variant offers distinct features and benefits, catering to different requirements and environments.

The electromechanical voltage stabilisers from Claude Lyons utilise advanced electromechanical technology to regulate voltage effectively. With a capacity of up to 4000 kVA, these stabilisers provide independent phase control and can correct input voltages within a range of +/- 25%. They are particularly suited for scenarios where the main power supply voltage significantly exceeds the appliance requirements. By reducing voltage levels by up to 12%, these stabilisers not only prolong the lifespan of your equipment but also offer energy savings of up to 20%, making them indispensable for efficient power management.

The electronic voltage stabilisers boast a maintenance-free design and robust construction, making them ideal for tough environments and remote locations. Ranging from 500VA to over 3000kVA, these stabilisers offer single and three-phase options with input swing options of up to +/- 30%. Equipped with sophisticated electronic control systems, they provide seamless voltage regulation, ensuring uninterrupted performance over their lifespan. Customisable precision allows users to tailor voltage control according to their specific needs, ensuring consistent and reliable power supply for various applications.

Both variants excel in delivering stable voltage output, safeguarding your equipment from fluctuations and ensuring smooth operation. Whether you require electromechanical stabilisers for energy conservation and extended equipment lifespan or electronic stabilisers for maintenance-free operation and precision control in challenging environments, Claude Lyons offers solutions tailored to your requirements. Trusted across diverse industries including medical, broadcasting, communications, engineering, production, railways, and calibration laboratories, Claude Lyons stabilisers provide reliability, precision, and efficiency, making them essential assets for power management in any setting.

Electromechanical Voltage Stabilisers

Electromechanical voltage stabilisers offer dual benefits of optimising voltage regulation and conserving energy. By reducing voltage by up to 12%, they extend equipment lifespan and can save up to 20% energy, especially when power supply voltage exceeds appliance requirements. This makes them crucial for efficient power management.
