Original Press Release:

Medical / ITE 305 Watt Open Frame Power Supplies with Compact Size of 5” x 3” x 1.5”

March 2019 — Santa Clara, California, USA — Tumbler Technologies, Inc. + TRUMPower announces the release of the TTM305 series to its AC/DC switching power supply line-up. The TTM305 series is certified to the latest medical IEC 60601-1 Edition 3.1 and industrial IEC 60950-1 2nd Edition standards, making it suitable for both medical and industrial applications.

The TTM305 series is able to deliver 305W of continuous output power at 11 CFM forced air or up to 255W at convection cooling. It comes as an open frame PCB in a low profile of 5” (L) by 3” (W) by 1.5” (H) and is equipped with overvoltage, overcurrent, and short circuit protections. The TTM305 also has a low earth leakage current measuring 100µA and provides 5V/1A of standby power along with fan power of 12V/0.3A for the 12/48V models and 24V/0.2A maximum for the 24V output model. It can withstand a voltage of 4000VAC from input to output (2 MOPP), 1500VAC from input to ground and 1500VAC from output to ground.

Operating at a 90 to 264 VAC universal input, the 305W rated power supplies are available with 12V, 24V, and 48V outputs and can operate in ambient temperatures ranging from 0°C to +70°C (derating linearly to 50% load from 50°C to 70°C). The power supply’s active efficiency is 90% minimum at full load and has a no load input power consumption of 0.5W maximum when utilizing the remote off feature. Its 300,000 hours-minimum MTBF at full load at 25°C ambient per Telcodia SR-332 makes it a highly reliable power supply.

The TTM305 is approved to the latest medical standards, including IEC/EN 60601-1 Edition 3.1, ANSI/AAMI ES 60601-1: 2012, CSA C22.2 No. 60601-1: 2014 and the IEC/EN/UL 60950-1 2nd edition ITE standards. The power supply complies with IEC/EN 60601-1-2 4th edition medical EMC and immunity standards including EN 55011/FCC/CISPR11 class B (conducted and radiated emissions), EN 61000-3-2, EN 61000-4-2, EN61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6, EN 61000-4-8, EN 61000-4-11.
