Low-cost AC/DC medical and ITE power supplies in a compact size

TRUMPower and Tumbler Technologies has introduced a new addition to its AC/DC switching power supply line-up with the TTM210 series, which is comprehensively approved to industrial and medical standards. The series is able to deliver 210W of continuous output power at 11CFM forced air or 160W at convection cooling. It comes as an open frame PCB in a low profile 5" (L) x 3" (W) x 1.5" (H) package and has an active efficiency of 88% typically at full load. The power supply offers 2 MOPP between input and output and 1 MOPP between input and ground. The series can withstand voltages of 4,000VAC from input to output, 1,500VAC from input to ground, and 1,500VAC from output to ground. The series includes three standard models of single 12V, 24V, or 48V power supplies each with an actual earth leakage current measuring 100µA maximum at 264VAC, 63Hz. Operating at a 90 to 264VAC universal input, the series provides 5V/2A of standby power along with fan power of 12V @ 1A or 24V @ 1A maximum. The unit is equipped with overvoltage, overcurrent, and short circuit protections. It operates at 0C to +40C ambient, with derating of 100% load at 0C to 40C, 75% load at 60C and 50% load at 70C, which is relevant to convection and forced-air cooling conditions. Its 300,000 hours-minimum MTBF at full load at 25C ambient per Telcodia SR-332 makes it a highly reliable power supply. Attachments area
