Krykard servo-controlled voltage stabilisers from alacrity electronics provides multiple solutions for industrial needs. They are also complete protection systems with electronic cutoff for under/over-voltage, overload, short circuit, surges and spikes, single-phasing and service bypass. These servo voltage stabilisers are energy savers for lighting loads particularly in industrial environment. They provide voltage specifically chosen to optimise functioning of fluorescent [mv/sv/mh] lighting systems, reducing energy consumption by up to 25 per cent, with marginal reduction in illumination levels. The servo voltage stabilisers also enhance life of lighting systems. In addition they help users protect and increase productivity of equipment used in production of cnc machine tools; textile spinning/weaving/knitting/proc machines; garment/offset printing/leather machines; medical/analytical equipment, etc. The patented aluminium foil technology based buck-boost transformers, duplicated protection circuit and appropriate component selection ensures high reliability. Models for various input voltage ranges, continuous duty full-load operation and efficiency >97 per cent are available which ensure low cost of ownership. The product range is available from 1 kv a to 1000 kv a in 1-, 2-, and 3-phase and in air/oil cooled models.
