100W Medical / ITE Certified 2in x 4in Power Supplies

May 01, 2019 by Scott McMahan

TDK Corporation introduced the TDK-Lambda brand CUS100ME series of ac-dc 100W rated power supplies. When conduction cooled, the CUS100ME series can deliver 50W without the need for forced air cooling. Certified to medical and ITE standards for Class I and II (no earth ground connection) operation, the series meets both class B radiated and conducted emissions.

CUS100ME target applications include medical, dental, home healthcare, broadcast, test and measurement, LED lighting, and industrial equipment.

Available with 12V, 15V, 18V, 24V, 28V, 36V, and 48V outputs, the CUS100ME operates from an 85Vac to 264Vac input. It has operating efficiencies of up to 94%. Off-load power consumption is below 0.5W

The open-frame version is in the industry standard 50.8mm x 101.6mm (2in x 4in) footprint with a height of 31.5mm. Convection cooled, it can deliver 100W at 50°C and 60W at 70°C. With forced air cooling, it can provide 100W at 70°C and 75W at 85°C. With a U-channel construction, CUS100ME measures 64mm x 116mm x 38.5mm (WxLxH). A cold plate enables conduction cooling to provide 100W at 70°C and 50W at 80°C. Top fan or cover options are also available.

Input to output isolation is 4kVac (2 x MoPP), input to ground is 1.5kVac (1 x MoPP), and output to ground is 1.5kVac (1 x MoPP), making the power supply series suitable for B and BF rated medical equipment. Touch current is a maximum of 100µA, and leakage current is less than 250µA. 5,000m is the maximum operating, storage, and transportation altitude.

All the power supplies in the series are certified to IEC/EN/ES/CSA 60601-1, IEC/EN/UL/CSA 62368-1, and IEC/EN/UL/CSA 60950-1 with CE marking for the Low Voltage, EMC and RoHS Directives. TDK designed the CUS100ME to meet IEC61010-1, and EN 60355-1 compliant versions are also available. Both Class I and Class II versions are compliant to EN 55011-B and EN 55032-B (radiated and conducted), and meet the EN 61000-3-2 harmonics, IEC 60601-1-2 Edition 4 and IEC 61000-4 immunity standards.

TDK backs the power supplies with a five-year product warranty.
