Medical Power Supplies Have Class II Input and Level VI Efficiency
TDK Corporation announces the introduction of the TDK-Lambda medically certified DTM65-C8 external power supplies. This series offers a class II input, thus does not require an earth ground connection and meets the stringent Level VI DoE standards for efficiency. The DTM65-C8 is also is certified to the IEC 60601-1 and 60601-1-11 medical standards, making it suitable for a variety of hospital and healthcare applications, including diagnostic and monitoring equipment.
The DTM65-C8 is housed in a rugged, vent-free IP21 rated enclosure, measuring 106 x 60 x 31mm. AC is applied using a standard IEC60320-C8 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 264-Vac input, the 40- to 65-W adapters are available with 5V, 12V, 15V, 19V, 24V, 28V and 48V outputs and can operate in ambient temperatures ranging from 0 to +60 degrees C (with derating). In addition to satisfying DoE requirements with an average efficiency of greater than 88% (12V models or higher), the power supplies have an off-load power draw of less than 0.21W.
The DTM65-C8 also 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 and radiated emissions and EN 60601-1-2 immunity standards.
