The RWS50B-48 is a 50W single-output AC-DC power supply with a 48V output, designed for general-purpose industrial applications. It is housed in a metal case measuring 81.5 x 82 x 34 mm and operates from 85 to 265 Vac input with an efficiency of 87% at 115 Vac and 88% at 230 Vac. It meets IEC62368-1 safety standards and Class B EMI compliance per EN55011/EN55032-B, FCC Class B, and VCCI-B. The unit features a 7-year warranty, convection cooling, and supports an operating temperature range of -20°C to +70°C with derating above 45°C. It has a hold-up time of 20 ms, a leakage current of less than 750 μA, and a 500V output-to-ground withstand voltage.
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.
Offering solid performance at a reasonable price, the RWS-B series of 50 to 1500W power supplies feature 10 year electrolytic capacitor lifetimes, ensuring long field life. The products are backed by a seven year warranty and are available with output voltages from 5 to 48V. In addition to IEC/EN/UL 60950-1 certification, medically certified RWS1000B/ME and RWS1500B/ME models to IEC 60601-1 are also available. All RWS-B models operate from a universal AC input of 85 - 265V to meet a wide range of applications, including industrial, medical, test & measurement, broadcast, communications and LED signage. .
