The CUS350M-18/F is a 350W AC-DC power supply with a 18V output, designed for medical and ITE applications requiring quiet operation. It delivers up to 414W with forced air cooling and includes a 5V 0.5A standby output, a 12V 0.3A fan supply, a Power Good signal, and remote on/off functionality. The unit is certified to IEC/EN60601-1 with 2x MOPP isolation, meets EN55011/EN55032-B conducted EMI limits, and complies with IEC61000-4 and EN60601-1-2:2015 immunity standards. It operates from 85-265V AC input, has an efficiency of 94% at 230V AC, and features a compact 190 x 87 x 40 mm (7.5 x 3.4 x 1.6 in) footprint with screw terminal and JST connectors. Derating applies at low input voltages, and the operating temperature range is -20°C to +70°C with convection or forced air cooling.
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.
Rated at 350W with convection cooling and up to 420W with forced air, the medical and ITE certified CUS350M is ideal for applications where audible noise cannot be tolerated, including hospital, dental, broadcast and professional audio equipment. With efficiencies of up to 94%, the CUS350M meets the ErP Directive and consumes <0.5W in standby mode. The preferred “/F” suffix models have a 5V 0.5A standby output, an auxiliary 12V 0.3A output, remote sense, remote on/off and an isolated DC good signal.
