TDK Corp. has introduced its TDK-Lambda medical-certified DTM165 adapter power supplies.  Suitable for a variety of hospital and healthcare applications, including diagnostic and monitoring equipment, the product also meets the required efficiency level V standards for medical equipment.

The DTM165 is housed in a rugged, vent-free enclosure, measuring 170 x 85 x 44mm.  AC is applied using a standard IEC60320-C13 cable and DC provided through a four pin Power-DIN connector.  Other connectors are available upon request.  The adapters also feature over-voltage and over-current protection.

Accepting a 90 to 264VAC input, the 160 to 165W adapters are available with 12V, 15V, 19V, 24V, 28V, 36V and 48V outputs and can operate in ambient temperatures ranging from 0 to +60oC (with derating).  In addition to satisfying CEC, ERP and EISA requirements with an average efficiency of greater than 87%, the power supplies have an off-load power draw of less than 0.5W.

The DTM165 series conforms to the IEC 60601-1 3rd edition medical standard with 4kVac input to output isolation (2 x MOPPs) and 1.5kVac (1 x MOPP) between input to ground.  Leakage current is less than 300µA.  The series has been certified to ANSI/AAMI    ES 60601-1, CAN/CSA-C22.2 No. 60601-1-08, EN 60601-1 and carries the CE mark.  All models meet EN 55011-B, FCC Class B conducted & radiated emissions and EN 60601-1-2 immunity standards.
