The RTW48-1R1L is a 50W AC-DC power supply in the RTW series, designed for industrial applications with a universal input range of 85-265VAC and 120-375VDC. It provides a 48V DC output with adjustable range of 38.4-52.8V and a maximum output current of 1.1A. The unit features remote on/off control, overcurrent and overvoltage protection, and meets EN61000-3-2 for power factor. It has an efficiency of 82% at 100VAC and 85% at 200VAC, with a maximum ripple and noise of 300mV. The package measures 22 x 82 x 124mm and is mounted via a vertical terminal block (suffix L). It complies with UL60950-1, CSA60950-1, EN60950-1, and CE Mark safety standards, and is SEMI F47 compliant. Operating temperature ranges from -10°C to +71°C with derating, and humidity tolerance is 10-95% RH non-condensing. The unit has a 5-year warranty and operates via convection 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.
Having an ultra-low profile, the enclosed RTW series of 50 to 300W power supplies provide solutions where space is extremely limited. The height of the 300W RTW is just 40mm with the 50W model measuring 22mm. Output voltages of 3.3, 5, 12, 15, 24, 28 and 48V cover the most popular applications. All models are convection cooled.
