TDK Corporation announces the introduction of the DTM300 series of medically certified 300W external power supplies. Certified to the latest IEC 60601-1 & 60601-1-2 medical standards, the products have 4,000Vac 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.

LA008115 - DTM300

The series is available with six commonly used output voltages; 12, 19, 24, 28, 48 and 54Vdc and can operate from a 90 to 264Vac input via a standard IEC 60320-C14 (3-prong) or 60320-C18 (2-prong) connector. The output cable is terminated with a 10-pin Molex Mini-Fit® connector, with other connector types available on request.

All models have an average efficiency level of >88% and an off-load power consumption of less than < 0.5W, enabling the series to fully meet the DOE Efficiency Level VI requirements. The adapter enclosure is vent-free (no cooling fan) 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. TDK-Lambda’s medical safety compliance extends to providing 2 x MoPPs (Means of Patient Protection) input to output. Touch current is <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.
