Medical and ITE certified external power supplies meet EU CoC Tier 2 efficiency standards

TDK Corporation has introduced the TDK-Lambda brand DTM250-D external power supplies rated at 250W output power. Certified to both 60601-1 (medical) and 60950-1 (ITE) standards, the series also satisfies the latest EU CoC (Code of Conduct) Tier 2 and US DoE Level VI efficiency standards. Applications include B and BF rated medical products, test, measurement and portable communications equipment. The convection cooled device is packaged in a rugged, vent-free, plastic enclosure measuring 45mm high, 90mm wide and 200mm length. As standard, the power supply is fitted with a Molex Mini Fit output connector with other types available upon request. The 90-264VAC input is applied via an IEC 320-C13 line cord. Seven output voltages are available (12V, 19V, 24V, 28V, 36V, 48V and 54V) and can operate in ambient temperatures from -20C to +60C with applicable derating below 0C and above 40C. Average efficiency is greater than 89% and off-load power consumption is less than 0.15W, measured in accordance with the EU and US efficiency regulations. The units are safety certified to IEC/EN/UL 60950-1, IEC/EN/UL 60601-1 with CE marking for the Low Voltage, EMC and RoHS2 Directives. The DTM250-D also complies with IEC 60601-1-2 Edition 4:2014, EN 55011-B, EN 55032-B EMC and immunity standards. Operational altitude is 5,000m.
