For most applications, servo-electronic (also known as electromechanical) -based AC power conditioners and voltage stabilizers have proven to be a very reliable and cost-effective voltage stabilization solution, with models available to accommodate a variation input voltage of over 40% while still delivering 1% accuracy on the output.
Composed of a transformer that has its secondary winding connected between the mains supply and the load, the primary voltage is controlled automatically through a motor-driven variable transformer, which guarantees a continuous, smooth and very stable output voltage.
High voltage / transient spikes are normally limited by the inclusion of ‘Spike Clippers’. These clippers typically limit transients to twice the maximum supply voltage. However, buyers should note that to reduce spikes to totally harmless levels, it is often necessary to request additional spike attenuation protection from your supplier.
While electronic servo stabilizers contain some moving parts, the experience of the last 25 years in some of the most demanding power conditions has shown that design is a very reliable method of delivering voltage regulation with only a low level of maintenance. continuous required. by universally available skill sets.
Long service life, compact size, and low cost of ownership make servo-electromechanical stabilizers economical solutions for a wide variety of applications in industry, commerce, mining, aerospace, computing and telecommunications, and typically it is the recommended design solution for most applications.
