Medical power supplies offer Class I or Class II inputs

The DTM300 series from TDK is a family of level VI medical 300W external power supplies. Certified to the latest IEC 60601-1 and 60601-1-2 medical standards, the products have 4000V AC isolation from input to output and are offered with either a Class I or Class II input.

The series is intended to power a range of hospital, dental and healthcare products for monitoring, imaging and diagnostic applications. ITE safety certifications are also included for industrial, test and measurement equipment.

The modules are available with six output voltages; 12, 19, 24, 28, 48 and 54V DC and can operate from a 90 to 264V AC input via a standard IEC 60320-C14 or 60320-C18 connector. The output cable is terminated with a 10pin Molex Mini-Fit connector, with other connector types available on request.

All models are said to have an average efficiency level of more than 88% and an off-load power consumption of less than 0.5W, enabling the series to meet the DOE Efficiency Level VI requirements. The adapter enclosure is vent free and measures 222mm in length, 112mm in width and 45mm in height.

The DTM300 has been certified to IEC/ES/CSA/EN 60601-1, IEC/UL/CSA/EN 60950-1 and carries the CE mark for the low voltage, EMC and RoHS2 directives. Medical safety compliance extends to provide 2 x MoPPs input to output.

Touch current is less than 100µA and Class I models are suitable for BF rated equipment. All models comply with EN 55011-B, EN 55022-B, EN 55024-B, FCC-B and EN 60601-1-2 Ed4:2014 EMC standards.
