Medical 40-65W external power supplies comply with the EU Tier 2 v5 and US DoE Level VI efficiency standards T
DK Corporation (TSE 6762) announces the introduction of the TDK-Lambda brand DTM65-D external power supplies rated at up to 65W output
power. Certified to the IEC 60601-1 medical standard, the series complies with the latest EU CoC (Code of Conduct) Tier 2 v5 and US DoE Level VI efficiency standards. Applications include medical products, industrial computing, life sciences and laboratory equipment. Packaged in a rugged, vent-free enclosure, the DTM65-D measures 132mm x 69mm x 40mm (L x W x H). Eight outputs are available (5V, 12V, 15V, 19V, 24V, 28V, 36V and 48V) with connections made using a standard 4-pin power DIN latching connector, with other types available upon request. The 90 - 264Vac input assures global operation and is applied through a three-pin IEC 320-C14 receptacle. The operating temperature is -20ºC to +60ºC, which derates linearly to 75 per cent load from 51ºC to 60ºC. Average efficiency is greater than 89 per cent (>87.3 per cent for the 5V model) and the off-load power consumption is less than 0.15W. The units are safety certified to ANSI/AAMI ES 60601-1, CAN/CSA-C22.2 No. 60601-1-08, IEC/EN 60601-1, and carry the CE mark for the Low Voltage, EMC and RoHS Directives. The units also comply with IEC 60601-1-2 Edition 4:2015, EN 55011-B EMC and FCC Part 18 Class B emissions and immunity standards. Input to ground isolation is 1,500Vac and input to output 4,000Vac (2 x MoPP), with a touch current of <100µA and a leakage current of <300µA. Operational altitude is 5,000m.

COSEL's configurable power supplies shorten time to market for medical applications
C
osel Co has launched a complete line up of configurable power supplies for medical applications, the AME series. Based on COSEL's digital power expertise and optimised topology for high efficiency, the AME series comprises of four models, AME400F, AME600F, AME800F and the AME1200F, together covering applications from 400W to 1200W. Each version can host independent output modules that can be combined
20 October 2019
and mixed to offer a unique configuration as required by the application. To perfectly optimise configuration to customers’ requirements, two versions of output modules are offered, 120W and 240W. Both modules are available in four output voltages, +5V, +12V, +24V and +48V. Designed for demanding medical applications, the AME series input/output isolation complies with 2MOPP requirements.
Components in Electronics
The AME moular concept is extremely flexible. Each module performs as a standalone power unit, and control and monitoring functions can be accessed via a single connector. The 240W module includes ON/OFF remote control, alarm signals, voltage sensing, output voltage and current control. Output voltage can be adjusted by using the built-in potentiometer or an external voltage. When using external voltage control, the output voltage can be trimmed down to
almost zero volts. By using the current trimming function (ITRM) the module can operate as a constant current source. With its medical focus, AME series' input to output isolation complies with 2MOPP and its input to ground with 1MOPP. AME is approved in accordance with UL62368-1, C-UL (CAN/CSA-C22.2 No.62368-1), EN62368-1, ANSI/AAMI ES60601-1, C-UL (CAN/CSA-C22.2 No.60601-1), EN60601-1 3rd edition, and it complies with IEC60601-1-2 4th Edition.
