TDK has announced the XMS500 series of AC-DC power supplies, rated at 500 W output power, with a Class I and Class II (no earth ground connection) construction. The series conforms to curve B conducted and radiated emissions, with a 6 dB margin and has a low leakage current of less than 150 µA. The high operating efficiency and mechanical design enables the XMS500 to operate at full load with airflow rates of just 1 m/s, reducing audible noise. Applications include home healthcare, hospital, imaging and clinical diagnostic systems in addition to industrial, test and measurement and communications equipment.

The XMS500 accepts a 90 VAC to 264 VAC input, withstanding 300Vac for five seconds and can operate in ambient temperatures of up to +70°C, derating linearly above 50°C by 2.5% per °C. The open frame version measures 102 mm x 180 mm x 37 mm and the U-channel 107 mm x 180 mm x 39.5 mm. The low profile allows installation in systems where space is limited.
All models are certified to IEC/EN/UL/CSA 60601-1 and IEC/EN/UL/CSA 60950-1 with CE marking for the Low Voltage, EMC and RoHS2 Directives. The series is compliant to EN 55011-B, EN 55032-B conducted and radiated emissions (for both Class I and II), EN 61000-3-2 harmonics, IEC 60601-1-2 Edition 4, and IEC 61000-4 immunity standards.
Input to output isolation is 4,000 VAC (2 x MoPP), input to ground isolation 1,500 VAC (1 x MoPP) and output to ground isolation is 1,500 VAC (1 x MoPP) for suitability in B and BF rated equipment.
