Fanless medical and ITE grade power adapters suitable for BF rated applications

Tumbler Technologies + TRUMPower has released its TMA400 desktop power adapter series. The power supplies offer a touch current of less than 100µA at 264VAC and withstand voltages of 4,000VAC from input to output (2MOPP), 1,500VAC from input to ground (1MOPP), and 1,500VAC from output to ground (1MOPP), allowing them to be used for BF rated applications. The series is certified to the latest ITE and medical grade safety standards, making them exceptionally versatile for many applications. Adding to its versatility, the series comes available with five single output voltages of 12V, 19V, 24V, 28V, and 48V.

The power supplies have a profile of 8.74” (L) x 4.41” (W) x 1.77”, are equipped with an IEC 320/C14 AC inlet and have a standard 10-pin Molex Mini-Fit output connector. The series has peak power capabilities of 480W at 115VAC or 520W at 230VAC for three seconds. The power adapters offer a minimum efficiency of 87.5% at full load, 115VAC/230VAC and 92% at 80% of full load, 230VAC. The power adapters support operating altitudes up to 5,000m and operating temperatures between -20C to +60C ambient while derating linearly from 100% load at +40C to 50% load at +60C. It has an MTBF of 230,000 hours-minimum at full load, 25C ambient, calculated per Bellcore TR-332, making it an extremely reliable power supply.

The power supply is certified to the most recent ITE standards of IEC/EN/UL/CSA C22.2 62368-1(3rd Edition). It is also certified to the latest IEC/EN/UL/CSA C22.2 60601-1 (Edition 3.1), ANSI/AAMI ES 60601-1 (Edition 3.1), and IEC/EN 60601-1-2 (4th Edition) medical standards. The power supply complies with EMC and immunity standards, including EN 55011, FCC, VCCI Class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-3-3, EN 61000-4-2 (ESD at ±15kV air and ±8kV contact), EN61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, EN 61000-4-11.
