TRUMPower Releases 2.2x Higher Power Density 330W GaN FET AC/DC Power Adapter Meeting Latest 62368-1 Standards

September 2019 — Santa Clara, California, USA — Tumbler Technologies + TRUMPower introduces its new TGA330 series power adapters which achieves a power density greater than 100W/cubic inch. The new line addresses the need for compact 330W solutions for industrial and ITE applications. Using the power supply allows for early compliance to the new IEC 62368-1 hazard-based, performance-oriented standards, which will be replacing the current IEC 60950-1 safety standards on December 20, 2020.

The new TGA330 series comes in a slim profile of 7.87” (L) by 3.94” (W) by 1.06” (H) and is available with either a 19.5V or 24V output. The power adapter is furnished with an IEC 320/C14 AC inlet and has a standard output connector of a 4 pin DIN plug. Please contact TRUMPower to request additional connector and cable options.

Operating at a 90 to 264 VAC universal input, the series supports operating altitudes up to 5,000 meters and operating temperatures between 0°C to +70°C ambient, while derating linearly from 100% load at +40°C to 60% load at +70°C. The power supply is also equipped with standard over current, over temperature, and over voltage protections. It has 300,000 hours-minimum MTBF at full load, 25°C ambient, calculated per SR332, making it a highly reliable power supply.

The power supply series carries the CE marking, is RoHS compliant, and is approved by UL/cUL and TUV to the latest ITE standards, including UL/EN/IEC 62368-1, CSA 22.2 No. 62368-1. The power adapter complies with EMC and immunity standards including EN 55032, CISPR 32/FCC,VCCI class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-3-3, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, EN 61000-4-11. With a >92% efficiency @ full load, the series meets DoE Level VI and CoC Version 5 Tier 2 standards.
