Medical / ITE Certified 2x4” Power Supplies Provide Optimum Performance up to 85°C Ambient Temperatures

San Diego, CA – January 2018 –

TDK Corporation announces the introduction of the TDK-Lambda brand CUS150M series of AC-DC 150W rated power supplies, with the capability of operating in ambient temperatures of up to 85°C without the need for forced air cooling.  Certified to medical and ITE standards for Class I and II (no earth ground connection) operation, the product meets both curve B radiated and conducted emissions.  CUS150M target applications include medical, home healthcare, dental, test and measurement, broadcast and industrial equipment.

Initially available with 12V, 24V and 48V outputs, (15V, 18V, 28V and 36V models to follow in Q1 2018), the CUS150M operates from an 85 to 264Vac input and has operating efficiencies up to 91%.  Off-load power consumption is less than 0.5W and a 10-12V 0.5A fan supply is fitted as standard.  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 120W at 40°C, or with forced air cooling 150W at 50°C, 140W at 70°C and 75W at 85°C.  With a U-channel construction, measuring 64 x 116 x 38.5mm (WxLxH), the CUS150M can be conduction cooled via a cold plate to deliver 150W at 50°C, 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 and IEC/EN/UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.  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.
