The new TTM305 series of AC/DC switching power supplies from TRUMPower is suitable for medical and industrial applications thanks to its latest medical IEC 60601-1 Edition 3.1 and industrial IEC 60950-1 2nd Edition compliance.
The power supplies are available with 12V, 24V, and 48V outputs and are operating at a range from 90 to 264 VAC universal input. They can deliver 305W of continuous output power at 11 CFM forced air or up to 255W at convection cooling. They also have a low earth leakage current measuring 100µA and can withstand a voltage of 4000VAC from input to output (2 MOPP), 1500 VAC from input to ground and 1500VAC from output to ground.
They are protected from overvoltage, overcurrent and short circuits and can operate in ambient temperatures from 0°C to +70°C. Their active efficiency is at 90% minimum at full load with 300,000 hours-minimum MTBF.
