The RWS1000B-48 is a 1000W single-output AC-DC power supply designed for general-purpose applications, providing a 48V output with a voltage range of 40.8V to 57.6V and a maximum current of 21A. It accepts an input voltage range of 85 to 265Vac and operates at 47 to 63Hz, with a power factor of 0.98 at 100Vac and 0.95 at 200Vac. The unit meets IEC62368-1 and EN62477-1 (OVC III) safety standards and complies with EN55011/EN55032-B, FCC Class B, and VCCI-B EMI limits. It features a compact enclosed design measuring 127 x 63 x 198mm, screw terminal input/output connections, remote sense capability, and optional remote on/off and standby 5V/1A outputs. Efficiency is 85% at 115Vac and 88% at 230Vac. The power supply operates from -20°C to +60°C with derating above 50°C, and includes overcurrent, overvoltage, and overtemperature protection. It carries a 7-year warranty in the Americas and EMEA regions.
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. .
