conversion for industrial control, automation and machinery applications. Available with configurable primary and secondary voltages (standard: 380V \/ 400V \/ 415V) and rated for 50Hz or 60Hz systems, this transformer is designed for low-voltage networks (&lt;1kV). Its dry, air-cooled construction eliminates oil, reduces fire risk and lowers routine maintenance \u2014 making it a safe, cost-effective choice for motor control centers, CNC systems, PLC cabinets and distribution panels.\t\t\t\t<\/div>\n\t\t\t\t<a href=\"#\" rel=\"nofollow\" class=\"wd-more-desc-btn\" aria-label=\"Read more description\"><span><\/span><\/a>\n\t\t\t<\/div>\n\t\t\t<div class=\"
