TDK-Lambda has introduced the CUS30M and CUS60M Series of AC-DC power supplies, rated at 30 W and 60 W output power. Certified to medical and ITE standards for Class I and II operation, the products meet both curve B radiated and conducted emissions without the need for additional filtering or shielding. The CUS30M and CUS60M target applications include medical, home healthcare, test and measurement, broadcast, industrial controls, and household appliances. Available in the industry-standard 2" x 3" footprint, these power supplies can accept an 85 to 265 VAC input and have operating efficiencies up to 90%. Off-load power consumption is <0.3 W for the CUS30M and <0.5 W for the CUS60M. The operating ambient temperature range is -20°C to +70°C (-30°C start-up), derating to 50% load at 70°C.
All CUS30M and CUS60M 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, EMC, and RoHS2 Directives. All models have also been evaluated for Class 2 limits in accordance with UL 1310 and standard IEC 60335-1 for household and similar electrical appliances. These series are compliant to EN 55011-B and EN 55032-B (radiated and conducted) and meet the EN 61000-3-2 harmonics and IEC 60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
