450W GaN AC

TRUMPower has integrated gallium nitride (GaN) transistors from Transphorm into a 450W AC-DC power adapter series for medical and enterprise applications.

The TGM450 AC-DC power supplies have an average efficiency of up to 95% and address the need for compact and fan-less power adapters to be used in both industrial and medical applications with compliance to the latest medical 60601-1 and ITE 62368-1 approvals.

The power supplies from this series have a touch current of less than 100µA and withstand voltages of 4,000 VAC from input to output (2 MOPP), 1,500 VAC from input to ground (1 MOPP), and 1,500 VAC from output to ground (1 MOPP), making them suitable for BF rated applications.

The power adapters are available with 4 standard single output voltages of 12V (400W), 24V, 48V, and 56V. The supplies have operating temperatures between -20°C to +60°C ambient, while derating linearly from 100% load at +40°C to 50% load at +60°C and operate at altitudes up to 5,000 meters. The power adapters are also extremely reliable with an MTBF of 300,000 hours minimum at full load, 25°C ambient, calculated per Telecordia SR-332.

The units come in a compact 10” x 4.57” x 1.85” (254 x 116 x 47mm) enclosure and are equipped with class I IEC 320/C14 AC inlet. The standard output connector for the 12V model is a Molex Mini-Fit receptacle P/N: 39-01-2125 with Molex terminal P/N: 45750-3111 with a cable length of 800mm. The standard output connector for the 24V-56V output models is a Molex Mini-Fit receptacle P/N: 39-01-2065 with Molex terminal P/N: 45750-3111 with a cable length of 1,200mm. The standard TGM450 series has separated AC ground and DC return, but it is available to be connected upon request.
