100W Medical / ITE Certified 2x4” Power Supplies Deliver 50W at 80°C Ambient when Conduction Cooled

San Diego, CA – April 2019 –

TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda brand CUS100ME series of AC-DC 100W rated power supplies, with the capability of delivering 50W in ambient temperatures of 80°C when conduction cooled 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, home healthcare, dental, test and measurement, broadcast and industrial equipment.

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

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

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

All the power supplies 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. The CUS100ME is designed to meet IEC61010-1 and EN 60355-1 compliant versions 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.
