Medical external power supplies comply with DoE level VI and EU Tier 2 v5 efficiency standards
TDK Corp. has announced 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.
Accepting a 90 to 264 VAC input, the 40- 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 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% (greater than 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, and IEC/EN 60601-1, and it carries the CE mark for the Low Voltage, EMC and RoHS2 directives. All models meet IEC 60601-1-2 Ed4:2014, EN 55011 Class B, and FCC Part 18 Class B emissions and immunity standards. Input to ground isolation is 1,500 VAC (1 x MoPP), input to output is 4,000 VAC (2 x MoPP), and output to ground is 1,500 VAC (1 x MoPP), with a touch current of less than 100 µA and a leakage current of less than 300 µA. All models are suitable for BF-rated equipment and can be operated up to an altitude of 5,000 m.
