All mains-powered equipment requires a supply which is maintained within certain limits. A low supply voltage will cause malfunction, whilst a high supply voltage will cause serious damage.

Users of electronic and other sensitive equipment need a steady and reliable flow of voltage free of transient spikes and electrical noise. No longer exclusively a problem for developing countries, the ever increasing demand for electrical power is now felt globally. Demand is now surpassing supply capacity and distribution, resulting in significant voltage fluctuations, power surges, and brownouts in the national power supply.

Claude Lyons has long been a trusted brand when it comes to voltage stabilisation.  Using the appropriate Claude Lyons AC voltage stabiliser or power conditioner helps overcome these problems, safeguarding vital communication networks and other safety-critical control applications.

A voltage stabiliser, also known as a voltage regulator, is a device that is designed to stabilise the incoming mains supply voltage before feeding it to the connected equipment. The stabiliser monitors the input voltage level and compares it to a pre-set value. If the incoming voltage level deviates from the pre-set value by more than the stabiliser’s output tolerance, it will adjust the voltage supply to ensure that it remains stable.

The voltage stabiliser adjusts the incoming supply voltage to ensure that the output voltage is within the tolerance range of the pre-set value. If the incoming voltage is higher than the pre-set value, it reduces the voltage. Conversely, if the incoming voltage is lower, it increases the voltage.

Some equipment can be permanently damaged by operating outside of its designed supply range. Some other types of equipment require a controlled supply voltage to ensure accuracy, consistency or repeatability of operation.

Voltage stabilisers serve as a protective barrier between your equipment and the mains supply. They continuously monitor and stabilise voltage fluctuations that occur in the incoming mains supply. This ensures that your valuable appliances receive a consistent and stabilised voltage input that is in line with the applicable equipment design voltage. As a result, your appliances will operate trouble-free, reliably, and enjoy a long operational life.

Claude Lyons TS and MS/MSB voltage stabilisers work by adjusting the voltage through the application of an in-phase or out-of-phase voltage of variable magnitude on the primary winding of a buck-and-boost transformer. This adjustment helps control the
voltage in the secondary winding, which is connected in series between the supply and the load.

As this operating system only supplies the buck-and-boost transformer with the corrective voltage necessary to restore the output within tolerance, the variable power is only a fraction of the total system power.

The current supplied by the voltage stabiliser is totally dependent upon the load applied. Provided the voltage stabiliser is operated within its specified limits, the output voltage delivered to the load will be maintained within the voltage stabiliser’s tolerance of the pre-set output voltage level. The voltage stabiliser automatically controls adjustments to the output voltage to counter voltage variations due to supply or load variations.

Claude Lyons SVR voltage stabilisers function similarly to other stabilisers, but instead of providing variable power to the buck-boost transformers, they utilise multiple buck-boost transformers that are switched in-phase or out-of-phase, thereby providing a highly efficient way of regulating the voltage output delivered to the load. By using a Claude Lyons SVR stabiliser, you can be assured that your output voltage will remain stable within the pre-set tolerance. The amount of current supplied.
