65W to 80W Adapter Power Supplies Comply With Level VI Efficiency Standards 

San Diego, CA – October 2015 –

TDK Corporation announces the introduction of the TDK-Lambda DT62D and DT80D adapter power supplies compliant with level VI efficiency standards.  Suitable for a variety of test and measurement, communications and industrial applications, the adapters meet the new stringent average efficiency and no-load power regulations, mandated by the US DoE applicable from February 2016.

Accepting a 90 to 264VAC input, the 65 to 80W adapters are available with 12V to 48V outputs and can operate in ambient temperatures up to +70oC for the DT62D and +60oC for the DT80D models (de-rating applies).  In addition to satisfying Energy Efficiency Level VI with an average efficiency of greater than 89% (DT80D) and 88% (DT62D), with an off-load power draw of less than 150mW (DT80D) and 210mW (DT62D), the products also meet CoC V5 Tier 2 requirements.

The series is housed in a rugged, vent-free enclosure, measuring 69 x 132 x 40mm.  AC is applied using a standard IEC 60320-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.

The DT62/80-D series has been certified to UL 60950-1, CSA C22.2-No.60950-1, EN 60950-1, and IEC 60950-1 and carries the CE mark.  All models meet EN 55022-B, FCC Class B conducted & radiated emissions and EN55024 immunity standards.
