Ultra-compact power adapter utilises GaN technology

TRUMPower has added the new GaN FET TTG160 power adapter series, which is aimed at industrial and ITE applications needing efficient electrical power conversion, to its lineup. The power supply offers an average efficiency of 91-93%, while providing a very low no-load power consumption of 0.21W. The 160W power adapter satisfies the latest global energy efficiency standards for external supplies with its compliance to DoE Level VI.

The series is provided in a compact 6.34” (L) x 2.13” (W) x 1.31” (H) enclosure for Class I models and 5.91” (L) x 2.13” (W) x 1.30” (H) enclosure for Class II models . The power supply gives a broad range of AC inlet options which comprise IEC 320/C6 and IEC 320/C14 for class I models or IEC 320/C8 for class II needs. The power adapter has five standard single output voltages of 12, 19, 24, 48, and 56VDC and delivers thermal shutdown to help protect it from over-temperature conditions. The series operates with a universal input range of 100VAC to 240VAC and operating temperatures between 0C to +70C ambient, while derating linearly from 100% load at +40C to 50% load at +70C (for 19V to 56V models) and from 100% load at +40C to 50% load at +60C (for the 12V model). The device has a high-power density of 10W/in3. The units are dependable with 300,000 hours minimum MTBF at 25C ambient, calculated per Telcordia SR-332.

The series carries the CE marking, is RoHS compliant, and is approved by UL/cUL, PSE and TUV to the latest ITE standards, including IEC/EN/UL 62368-1:2014, CAN/CSA 22.2 No. 62368-1-14 and IEC/EN/UL 60950-1 2nd edition. The power adapter complies with EMC and immunity standards comprising 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. It also meets energy star 2.0, ErP stage 2, CoC tier 2, NRCan & GEMS level VI standards.
