ISO 9001:2015 & Level VI Certified Manufacturer

Wall Plug-In Transformers

High-Efficiency External AC/DC Power Adapters, Switch-Mode Power Supplies & Medical-Grade Wall Power Solutions for Global OEM Applications.

High-Efficiency Wall Plug-In Power Supplies & AC Adapters

Many modern commercial, industrial, and medical devices require stabilized low-voltage power directly from standard grid lines. Triad Magnetics engineers and manufactures high-performance wall plug-in transformers—commonly designated as AC adapters, wall power supply units, wall bumps, or external power supplies. Our solutions eliminate internal thermal buildup within target electronics, significantly optimizing casing size, device weight, and long-term operating reliability.

OEM Global Compliance: All standard Triad wall plug-in transformers fully comply with the European Union RoHS 2015/863/EU Directive, US Department of Energy (DOE) Level VI energy efficiency standards, and international UL / cUL / CE safety standards.

Engineering Capabilities: From standard off-the-shelf catalog configurations to fully customized housing geometry, custom cable lengths, output plug polarities (-R models), and custom voltage matching, Triad's application engineers deliver precision power solutions tailored for high-reliability global deployment.
