Global Leader in Industrial Power Supplies

Thanks to our investments in research & development, PSTEK is now manufacturing and providing hundreds to thousands of kW induction heating systems annually in various fields, and holds an unparalleled position in the field of induction heating in Korea.

Before 2007, the production of GA heaters — which alloy coated zinc and steel sheets in the continuous galvanizing line (CGL) designed to produce galvanized steel sheets for automobiles — was monopolized by induction heating companies in advanced countries. In 2007, PSTEK became the first Korean company to successfully develop GA heaters with its own independently developed technology. In the heat treatment sector, PSTEK has also developed ultra-large heat treatment equipment for automotive components, oversized gears, ball races, large rolling rolls, and ship screw shafts, now in operation at leading Korean companies.

Based on our outstanding power supply technology, PSTEK also provides customized special power supplies. We have developed stable high-capacity and high-efficiency power supplies tailored to customer requirements, satisfying their expectations in terms of product quality and convenience. Representative products include boost converters for military defense equipment and power supplies for the implant extractor (Smilekey).
