500W Configurable AC-DC Power Supplies
TDK Corporation announces the introduction of the XMS500 series of AC-DC power supplies, rated at 500W 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 6dB margin and has a low leakage current of less than 150µA. The high operating efficiency and mechanical design enables the XMS500 to operate at full load with airflow rates of just 1m/s, reducing audible noise. Applications include home healthcare, hospital, imaging and clinical diagnostic systems in addition to industrial, test and measurement and communications equipment.
Designed as a configurable product, engineers can select from multiple standard options, to optimize both system performance and cost, without incurring development charges or minimum purchase quantities. The options include case styles (including an internal low speed fan), a choice of standby voltage, a 12V fixed or variable speed fan supply, remote on/off, AC fail and single or dual input fuses. 12V, 24V, 36V or 48V nominal outputs are offered, with other voltages upon request. The product has a five year warranty.
The XMS500 accepts a 90 to 264Vac 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 x 180 x 37mm and the U-channel 107 x 180 x 39.5mm. 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 4,000Vac (2 x MoPP), input to ground isolation 1,500Vac (1 x MoPP) and output to ground isolation is 1,500Vac (1 x MoPP) for suitability in B and BF rated equipment.
