40-65W Medical AC-DC External Power Supplies

TDK Corporation announces the introduction of the TDK-Lambda medical certified DTM65-D external power supplies.  This series meets the stringent DoE Level VI and EU Tier 2 v5 standards for efficiency and off-load power.  The DTM65-D is certified to the medical IEC 60601-1 standards, making it suitable for a variety of hospital, dental and healthcare applications, including diagnostic and monitoring equipment.

The convection-cooled DTM65-D is housed in a rugged, vent-free enclosure, measuring 132mm x 69mm x 40mm (L x W x H).  AC is applied through the standard IEC 60320-C14 (3-prong) socket and the output DC cable is fitted with a 4-pin Power-DIN connector as standard, withother connector types available upon request.  The adapters also feature over-voltage and over-current protection.

Accepting a 90 to 264VAC input, the 40 to 65W adapters are available with 5V, 12V, 15V, 19V, 24V, 28V, 36V and 48V outputs and can operate in ambient temperatures ranging from -20 to +60°C (derating linearly to 50% load from 40 to 60°C).  In addition to satisfying DoE Level VI and EU Tier 2 v5 requirements with an average efficiency of greater than 89% (>87.3% for the 5V model), the power supplies have an off-load power consumption of less than 0.15W.

The DTM65-D series has been certified to ANSI/AAMI ES 60601-1, CAN/CSA-C22.2 No. 60601-1-08, IEC/EN 60601-1, and carries the CE mark for the Low Voltage, EMC and RoHS2 Directives.  All models meet IEC60601-1-2 Ed4:2014, EN55011 Class B, FCC Part 18 Class B emissions and immunity standards.  Input to ground isolation is 1,500Vac (1 x MoPP), input to output 4,000Vac (2 x MoPP), output to ground 1,500Vac (1 x MoPP), with a touch current of <100µA and a leakage current of <300µA.  All models are suitable for BF rated equipment and can be operated up to an altitude of 5,000m.
