Medical / ITE certified 2×4-in. supplies work up to 85°C

January 31, 2018 By Lee Teschler

The TDK-Lambda brand CUS150M series of ac-dc 150-W rated power supplies operate 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 12 V, 24 V and 48 V outputs, (15 V, 18 V, 28 V and 36 V CUS150M models to follow in Q1 2018), the CUS150M operates from an 85 to 264 Vac input and has operating efficiencies up to 91%. Off-load power consumption is less than 0.5 W and a 10-12 V 0.5 A fan supply is fitted as standard. The product warranty is five years.

The open frame version is in the industry standard 50.8×101.6 mm (2×4 in.) footprint with a height of 31.5 mm. Convection cooled it can deliver 120 W at 40°C, or with forced air cooling 150 W at 50°C, 140 W at 70°C and 75 W at 85°C. With a U-channel construction, measuring 64x116x38.5 mm (WxLxH), the CUS150M can be conduction cooled via a cold plate to deliver 150 W at 50°C, 100 W at 70°C and 50 W at 80°C. Cover or top fan options are also available.

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