TDK-Lambda's 2" x 4" power supplies are suitable for operation in high ambient temperatures
The TDK-Lambda brand CUS150M series of 150 W rated AC-DC power supplies from TDK Corporation have 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 12 V, 24 V, and 48 V outputs, the CUS150M operates from an 85 VAC to 264 VAC input and has operating efficiencies up to 91%. Off-load power consumption is less than 0.5 W and a 10 V to 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 mm x 101.6 mm (2” x 4”) footprint with a height of 31.5 mm. Convection-cooled it can deliver 120 W at 40°C, or 150 W at 50°C, 140 W at 70°C, and 75 W at 85°C with forced air cooling. With a U-channel construction, measuring 64 mm x 116 mm x 38.5 mm (W x L x H), 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 250 µA. The maximum operating, transportation, and storage altitude is 5,000 m.
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.
