Medical 40-65W external power supplies

TDK Corporation has introduced TDK-Lambda brand DTM65-D external power supplies rated at up to 65W output power.

Certified to the IEC 60601-1 medical standard, the series complies with the latest EU CoC (Code of Conduct) Tier 2 v5 and US DoE Level VI efficiency standards. Applications include medical products, industrial computing, life sciences and laboratory equipment.

Packaged in a rugged, vent-free enclosure, the DTM65-D measures 132mm x 69mm x 40mm (L x W x H). Eight outputs are available (5V, 12V, 15V, 19V, 24V, 28V, 36V and 48V) with connections made using a standard 4-pin power DIN latching connector, with other types available upon request. The 90 - 264Vac input assures global operation and is applied through a three-pin IEC 320-C14 receptacle.

The operating temperature is -20ºC to +60ºC, which de-rates linearly to 75% load from 51ºC to 60ºC. Average efficiency is greater than 89% (>87.3% for the 5V model) and the off-load power consumption is less than 0.15W.

The units are safety certified to ANSI/AAMI ES 60601-1, CAN/CSA-C22.2 No. 60601-1-08, IEC/EN 60601-1, and carry the CE mark for the Low Voltage, EMC and RoHS Directives. The units also comply with IEC 60601-1-2 Edition 4:2015, EN 55011-B EMC and FCC Part 18 Class B emissions and immunity standards. Input to ground isolation is 1,500Vac and input to output 4,000Vac (2 x MoPP), with a touch current of <100µA and a leakage current of <300µA. Operational altitude is 5,000m.
