The CUS500M1-48 is a 500W AC-DC power supply for medical and ITE use, offering 48V output at 10.5A under forced air cooling or 6.3A convection cooled with 504W peak power. The open-frame model measures 127 x 76.2 x 37 mm and uses JST VHR-5N input and M4 screw outputs. It meets IEC/EN/UL62368-1 and 60601-1 with 2x MOPP isolation, complies with EN55032/EN55011 Class B EMI, and IEC61000-3-2 Class A harmonics. Efficiency reaches 96%, with 14ms hold-up time at 115Vac full load. Operating temperature ranges from -20°C to +70°C with derating, supporting convection or forced air cooling up to 2.7m/s. Overcurrent and overtemperature protection are latching, reset by AC cycle. Warranty is five years.
AC-DC converters have the functionality to extract a stable DC power supply by rectifying and controlling commercial power supplies. TDK offers an abundant lineup of TDK-Lambda brand AC-DC switching power supplies that adopt the "switching method" for the industrial equipment market. These power supplies are available in unit types, PC board types, power module types, on-board types, and DIN rail mount types, with a wide-ranging product lineup from models with a small capacity of several W to models with a large capacity exceeding 2 kW. TDK-Lambda offers "standard power supplies" that meet the various needs of its customers for keeping up with the changing times, including miniaturization and efficiency enhancement, compliance with safety standards, support for wide input, compliance with EMI (electromagnetic interference) standards and higher harmonic current regulation, compliance with the RoHS directive, and the adoption of digital control technologies.
The compact CUS500M1 series of single output AC-DC power supplies are available with 12V, 19V, 24V, 28V, 32V, 36V and 48V outputs in an industry standard 3 x 5 inch package and can deliver 500W with forced air cooling or 300W with 500W peak power when convection cooled.
CUS500M1 can be used in both Class I and Class II (no earth wire) applications and offers efficiencies of up to 96%. A cover with integral end mounted fan option is available.
Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with UKCA and CE marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions, and meet the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
Typical applications include medical (B and BF type), home healthcare, dental, test and measurement, broadcast, professional audio and industrial equipment.
