The Alpha 400W is an AC/DC modular power supply designed for industrial, medical, and instrumentation applications, offering up to 16 outputs with voltages up to 48V and current up to 300A. It features fast-on output terminals and a low-profile design. Input voltage range is 85 to 264Vac, with an input frequency of 47 to 63Hz. It provides 15ms minimum hold-up time, 75% typical efficiency at 230Vac and full load, and <2% ripple and noise with EIAJ measurement method. Overvoltage, overcurrent, and short-circuit protection are standard. It complies with EN 60950-1, UL 60950-1, CSA 22.2 No. 60950-1, and IEC 60601-1 medical safety standards as an option. Operating temperature range is 0°C to 70°C, with derating of 2.5% per °C above 50°C. Leakage current is selectable at 1.1mA, 500µA, 240µA, or 110µA. The unit is housed in a 5-slot chassis with forward 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.
