TDK-Lambda's medical certified DTM65-D external power supplies 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 132 mm x 69 mm x 40 mm (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 with other connector types available upon request. The adapters also feature overvoltage and overcurrent protection.

Accepting a 90 V_AC to 264 V_AC input, the 40 W to 65 W adapters are available with 5 V, 12 V, 15 V, 19 V, 24 V, 28 V, 36 V, and 48 V outputs and can operate in ambient temperatures ranging from -20°C to +60°C (derating linearly to 50% load from +40°C 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 5 V model), the power supplies have an off-load power consumption of less than 0.15 W.

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 1,500 V_AC (1 x MoPP), input to output 4,000 V_AC (2 x MoPP), output to ground 1,500 V_AC (1 x MoPP), with a touch current of <100 µA and a leakage current of <300 µA. All models are suitable for BF rated equipment and can be operated up to an altitude of 5,000 m.
